What is dust? DDT returns What is the dangerous smell of dust.

And many other countries. However, recently there have been a number of reports on the significantly exaggerated harm of DDT. There is an assumption that the main harm to mammals and birds is caused not by DDT itself, but by impurities (mainly dioxins) that occur when it is used. industrial production. WHO officially recommends the use of DDT for the prevention of malaria.

History of creation, obtaining, application

DDT (C 14 H 9 Cl 5) is a classic example of an insecticide. In form, DDT is a white crystalline substance, tasteless and almost odorless. First synthesized in 1873 by the Austrian chemist Othmar Zeidler, it was not used for a long time until the Swiss chemist Paul Müller discovered its insecticidal properties in 1939, for which he received the Nobel Prize in Medicine. in 1948 as "For the discovery of the high efficacy of DDT as a contact poison".

DDT is an extremely effective and very easy to obtain insecticide. It is obtained by the condensation of chlorobenzene (C 6 H 5 Cl) with chloral (Cl 3 CCHO) in concentrated sulfuric acid (H 2 SO 4). DDT is an externally acting insecticide, that is, it causes death on external contact, affecting nervous system insect. The degree of its toxicity can be judged by the fact that fly larvae die when less than one millionth of a milligram gets on the surface of their bodies. Thus, it can be argued that DDT is highly toxic to insects, while at appropriate concentrations it is harmless to warm-blooded animals. However, if exceeded, it also has a toxic effect. In particular, in a person whose body DDT can penetrate through the respiratory organs, skin, gastrointestinal tract, it causes poisoning, the signs of which are general weakness, dizziness, nausea, irritation of the mucous membranes of the eyes and respiratory tract. DDT poisoning is especially dangerous in the treatment of premises and seed. In addition, exposure to the body in large doses can lead to death. The data obtained as a result of clinical studies make it possible to determine the toxicity of DDT for humans as follows: see Table No. 1. Due to the danger of DDT poisoning, all types of work with it are carried out with the obligatory use of means personal protection(overalls, footwear, respirator, gas mask, goggles, etc.).

The benefits and harms of DDT

In addition to domestic use as a means of controlling pests such as flies, cockroaches and moths, as well as benefits for Agriculture As a tool for controlling pests such as the Colorado potato beetle and aphids, DDT has a number of universally recognized "heroic" merits on a global scale, among them the most significant are the following:

In January 1944, a typhoid epidemic in Naples was averted with DDT. This is the first winter epidemic of louse-borne typhus that has been stopped.
In India, thanks to DDT, not a single person died from malaria in 1965, while 3 million people died in 1965. The US National Academy of Sciences estimates that DDT saved 500 million lives from malaria during its use through 1970 .
In Greece in 1938 there were a million malaria patients, but in 1959 there were only 1,200.
In the Italian province of Lazia in 1945, the death rate from malaria per month was 65-70 people, and after they began to use DDT, it dropped to 1-2 people in 1946.
The use of DDT largely freed India of visceral leishmaniasis (vectored by Mosquitoes) in the 1950s and 1960s.

Thus, the world quickly gained positive experience with DDT. This experience has led to a rapid increase in the production and use of DDT. The growth in the production and use of DDT was not the only consequence of the "good practice". It also caused the formation in the minds of people of erroneous ideas about the non-toxicity of DDT, which in turn led to the cultivation of carelessness in the use of DDT and a disregard for safety standards. DDT was used everywhere and everywhere without complying with the requirements established by sanitary and epidemiological standards. The current situation could not but lead to negative consequences. For example,

in kindergarten, in Iran, when preparing porridge, having mixed up the cans, instead of powdered milk, the corresponding amount of DDT dust was poured into the boiler. Died, poisoned, several dozen;
in the early 1950s, the Colombian government forcibly sprayed peasants with DDT at their Ministry of Agriculture appointments to control head lice.

The peak of this euphoria came in 1962, when 80 million kilograms of DDT were used in the world for their intended purpose and 82 million kilograms were produced. After that, the volumes of production and use of DDT began to fall. The reason for this was the worldwide discussion about the dangers of DDT, which was due to the book of the American scientist Rachel Carson (Rachel Carson) "Silent Spring" ("Silent Spring", which means "Silent Spring" or "Silent Spring"), in which Carson argued that the use of DDT had a detrimental effect on reproductive function in birds. Carson's book caused a wide resonance in the United States. Various environmental organizations have taken Carson's side, such as the Environmental Defense Fund, the National Wildlife Federation. On the side of Carson's opponents, DDT manufacturers and the state administration supporting them, represented by the Environmental Protection Agency, stood up. The debate about the dangers of DDT soon escalated from national to international. However, Carson's conclusions about the dangers of DDT had no scientific basis.

In his book, Carson draws on the research of James DeWitt, summarized in his papers "Effects of Chlorinated Hydrocarbon Insecticides upon Quail and Pheasants" and "Chronic Toxicity to Quails and Pheasants of Certain Chloric Insecticides". insecticides” (“Chronic Toxicity to Quail and Pheasants of Some Chlorinated Insecticides”). Carson praises DeWitt's research, calling his experiments on quails and pheasants classic, but in doing so she misrepresents the data that DeWitt obtained in the course of his research. Thus, referring to DeWitt, Carson writes that "Dr. DeWitt's experiments (on quails and pheasants) established the fact that exposure to DDT, without causing any noticeable harm to birds, can seriously affect reproduction. Quails fed DDT diets survived throughout the breeding season and even produced a normal number of eggs with live embryos. But few chicks hatched from these eggs. However, Carson omits numbers in his book. The fact is that from quail eggs that ate food containing DDT in large quantities, namely 200 ppm (that is, 0.02%; for example, at that time the maximum permissible concentration of DDT for eggs established in the USSR was 0.1 ppm ), only 80% of the chicks hatched, however, 83.9% of the quail eggs in the control group, whose food was free of DDT, hatched. Thus, the difference between the quails fed with DDT and the control group was only 3.9%, which made it impossible to draw a conclusion regarding the impact of DDT on reproductive function in birds. Much later, it was found that DDT causes thinning of the egg shell and death of the embryos. However, different groups of birds vary greatly in their sensitivity to DDT; birds of prey are most sensitive, and under natural conditions a pronounced thinning of the shell can often be found, while chicken eggs are relatively insensitive. Due to omissions made by Carson in her book, most of the experimental studies were done with DDT-insensitive species (such as the quail), which often showed little or no shell thinning. Thus, Carson's book misdirected science by targeting birds that were not sensitive to DDT, thereby delaying research into DDT exposure in birds by 20 years. However, now we can talk about the impact of DDT on the environment from a scientific standpoint.

Degradation resistance

DDT is highly resistant to decomposition: neither critical temperatures, nor enzymes involved in the neutralization of foreign substances, nor light are able to have any noticeable effect on the process of DDT decomposition. As a result, when released into the environment, DDT somehow ends up in the food chain. Turning in it, DDT accumulates in significant quantities, first in plants, then in animals and, finally, in the human body. The calculation of Damen and Hayes (1973) showed that at each link in the food chain there is an increase in the content of DDT by a factor of 10:

Plants (algae) - 10x

Small organisms (crustaceans) - 100x

Pisces - 1000x

Predatory fish - 10000x

This rapid accumulation of DDT is clearly seen in the following example. So, in the study of one ecosystem in Lake Michigan, the following accumulation of DDT in food chains was found: in the bottom silt of the lake - 0.014 mg / kg, in crustaceans that feed on the bottom - 0.41 mg / kg, in various fish - 3-6 mg /kg, in the adipose tissue of gulls feeding on this fish - over 200 mg / kg.

The impact of DDT on humans

The available data on the effects of toxic effects of DDT on humans can be summarized as follows. DDT has an acute toxic effect on humans: in small and medium doses it causes poisoning, in adults for the most part without negative consequences in the future, in large doses it can cause death. DDT accumulates in the fatty tissues of the body, enters the mother's milk, and can enter the bloodstream. Theoretically, during weight loss, or due to long-term exposure, the accumulation of DDT in the body can lead to intoxication of the body. Objectively, the consequences of DDT accumulation in the human body have not been established. The impact of DDT does not have a carcinogenic (causing cancer), mutagenic (causing a permanent change in living matter), teratogenic (causing deformity), embryotoxic (causing changes in the fetus) effect on the human body, does not lead to a decrease in fertility (the ability to have offspring). DDT leads to the induction of microsomal enzymes, but does not entail any morphological changes in the liver, and enzymatic activity generally does not exceed the norm. The effect of DDT on the human immune system, apparently, is inhibitory in nature (it inhibits the activity of enzymes, in this case inhibition of the formation of antibodies), but this has not been definitively established.

It should be noted that many popular scientific sources contain categorical statements about the carcinogenic, mutagenic, embryotoxic, neurotoxic, immunotoxic effects of DDT on the human body. For example, DDT is alleged to cause or contribute to a variety of human diseases that were not previously considered to be associated with any chemical substance. These include cardiovascular disease, cancer, SARS, retrorental fibroplasia, poliomyelitis, hepatitis, and "neuropsychiatric manifestations". At the time these claims were made, the causes of all of these diseases without exception were unknown, or at least unproven. Needless to say, the DDT charge of predisposing to polio was dropped after the disease was brought under control through vaccination. Unfortunately, today there is no immediate possibility of combating cardiovascular diseases, cancer and many other less common diseases. pathological conditions human, the occurrence of which was attributed to DDT. Meanwhile, such irresponsible statements can bring great harm and, if taken seriously, can even interfere with the scientific search for the true causes and real measures to prevent these conditions.

The impact of DDT on other living organisms (except humans)

Available data on the effects of toxic effects of DDT on other living organisms can be summarized as follows. Aquatic microorganisms are more sensitive to the action of DDT than terrestrial ones. At a concentration in environment 0.1 µg/l DDT is able to inhibit the growth and photosynthesis of green algae.

Indicators of both acute and chronic toxicity for various kinds aquatic invertebrates DDT are not the same. In general, DDT exhibits high acute toxicity to aquatic invertebrates at concentrations as low as 0.3 µg/L, with toxic effects including reproductive and developmental disorders, cardiovascular changes, and neurological changes.

DDT is highly toxic to fish: LC50 values (96 h) obtained in static tests range from 1.5 µg/l (largemouth bass) to 56 µg/l (guppies). Residual levels of DDT above 2.4 mg/kg of winter flounder roe caused abnormal development of embryos; with similar residual concentrations, as was found, the death of fry of lake trout in natural conditions is associated. The main target of the toxic action of DDT may be cellular respiration.

Earthworms are insensitive to the acute toxic effects of DDT at levels in excess of those likely to occur under environmental conditions.

DDT can have an adverse effect on the reproductive function of birds, causing thinning of the egg shell (which leads to their destruction) and the death of embryos.

Talc, pyrophyllite, chalk, kaolin, gypsum, tripoli, silica gel and various clays are used as fillers. The most convenient are pyrophyllite and talc, which adhere better to plants.

The content of the active substance in the dust depends on its activity and purpose and is usually 1-10%. In the manufacture of dusts with a low content of the active substance (1.5-2%), the fillers must meet the following requirements: good grinding; do not cake during storage; well sprayed when making; do not cause decomposition during storage and application.

The filler must not react with or change its chemical and biological properties. Therefore, for example, alkaline fillers should not be used in the preparation of dusts, as they decompose. To reduce unproductive spraying and losses due to the drift of small parts, 3-5% mineral oil is added to the powders. Optimal dimensions powder particles during ground processing 15-25 microns, during aviation - 25-50 microns.

Use of powders

(ground dusting)

in the eighties of the last century, it was mainly used in the treatment of plants with a dense leaf cover. This application method was recommended for use in water scarce areas. The maximum processing efficiency was achieved in morning hours, before the dew disappears, or in the evening.

Presowing

(etching). At present, seed dusting powders are widely used to control plant diseases and to protect seedlings from damage by soil-dwelling pests.

Dry seed dressing agents are usually included in amounts from 1-2% to 80-90%, and the filler is used only in small quantities to improve the grinding of the drug and prevent caking during storage.

When using powders, in most cases for ground application or when dusting seeds, the degree (thickness) of grinding the preparation is of great importance: the finer (thinner) the preparation, the better it is retained on the surface of the seeds.

However, dusts are unsuitable for semi-dry and wet pickling, as they do not mix well with water due to their hydrophobicity.

Medical and household pest control

. Powders and dusts are used against crawling insects. These have a good effect on insects due to the fact that dust particles, due to their small size, are actively attracted and stick to the insect's body while moving along the treated surface. A constant contact with the toxicant is created, leading to the rapid death of the arthropod.

Despite the narrow field of application of pest control dusts, they have proven themselves well for treating dry basements against fleas, because in the absence of flooding, the dust remains active for several months.

Deratization

. Powders and dusts are used against rodents as rodenticide coatings.

By the ability to stick to hairy rodents, they differ (in descending order):

Of the poisons of cumulative action, numerous are used in the composition of dusts.

The active use of the method with poisons of holes and passages of rodents revealed its different effectiveness in relation to different species. In humid environments where gray rats, mixtures of poisons with fillers were poorly dusted, weakly adhered, and their effectiveness was not high. In dry places, the powder adhered better to the fur of the animals and proved to be more effective.

Properties

Positive properties

Long shelf life (up to 5 years)
Ability to withstand high and low air temperatures during storage
Relatively not big weight(compared to liquid forms)
fire safety

Negative properties

Due to the fact that talc has a pH of about 8.5 and is a slightly alkaline filler, many dusts and powders on talc quickly lose activity due to the hydrolytic decomposition of active substances, since most have a slightly acidic pH.

More resistant are dusts and powders on white soot, kaolin and other acidic fillers.

Scheme of the production of pesticide dusts

Principal technological scheme for the production of pesticide dusts:

1 - bunkers for feedstock; 2 - dispensers; 3 - screw conveyor; 4, 6 - mixers;

5 - mill; 7 - packaging unit; 8 - collection for dust; 9 - cyclone;

10 - filters for catching dust residues.

Dust production

The basic technological scheme for the production of dusts is shown on figure .

Dichlorodiphenyltrichloroethane, better known by the abbreviation DDT, was synthesized as early as 1874, but it was not until 1937 that the compound was discovered to be highly toxic to insects.

The first case of widespread use of the new insecticide was a massive DDT dusting of the Pacific Islands, undertaken by the American army before the liberation of the islands from the Japanese in 1942. These paratroopers were protected from malaria, dengue fever and other tropical diseases carried by insects. Winter 1944 american soldiers in Naples they were pollinated with dust to kill lice.

After the Second World War, a new insecticide began to be widely used to destroy agricultural pests, but after a while it turned out that this substance decomposes in nature extremely slowly, is transmitted through the food chain to other organisms, accumulates in them and slowly poisons them. In addition, insect lines resistant to DDT have appeared that can withstand even tenfold doses of the drug. Therefore, for almost thirty years, the use of DDT has been banned in most countries (the first was Sweden, which banned this insecticide in 1969). True, the World Health Organization has not banned DDT, but has not financed its purchases for a long time. developing countries. The World Bank does not even give loans to countries that still use this insecticide.

However, it now appears that no the best remedy to control malarial mosquitoes than DDT. When the insecticide was banned in South Africa, far behind other countries, in 1996, the incidence of malaria increased by more than six times, and five years later it was again allowed. Just don't spray tons of it from planes flying over cities, ponds, swamps and agricultural land. Careful use inside dwellings, experts now believe, is quite acceptable. According to WHO, two grams of DDT per square meter adobe walls reduce the likelihood of malaria infection of the tenants of the house by 90%. Spraying should be repeated only once a year. Therefore, the World Health Organization approved the use of DDT for indoor spraying, pointing out that it is not only the best weapon against malarial mosquitoes, but also the cheapest and most effective of insecticides. If used correctly, DDT does not pose a threat to nature or humans.

In addition, data on the accumulation of DDT and toxic products of its decay in wildlife have recently been called into question.

About twenty years ago, ecologists monitoring the content of toxic substances in the fat of marine mammals began to detect unknown organic compounds with chlorine atoms in the fat samples. In structure, they resembled DDT, and it was concluded that the drug and its decomposition products are carried by rivers to the ocean, and there they accumulate in mammals.

And just recently, in a vial of whale oil, preserved in the last whaler sailboat, put on eternal joke off the coast of Connecticut (USA), the same compounds were found - as many as 11 of their varieties. Since the fat sample dates back to 1921, when DDT was not produced or used, it remains to be concluded that these compounds are synthesized somewhere in the ocean. Where exactly - is still unclear, it is only known that something like DDT is produced by symbiotic bacteria living in sea sponges and, apparently, protecting their hosts from being eaten by this.

Bedbug bites are not dangerous for humans, the maximum that they can provoke is allergic reaction, itching and small rash. You can read about the consequences of bites. Bed bugs do not carry any serious diseases.

But, nevertheless, most people do not want to put up with such a forced neighborhood, and try to get rid of insects with all accessible ways, even folk. ABOUT folk remedies getting rid of bedbugs can be found by clicking on.

Among the wide range of modern drugs, dust does not give up its positions, it is still in demand and popular with most of the population, as in Soviet times. In this article, we will try to consider whether bed bug dust helps.

Dust from bedbugs - powdered drug, which includes such constituents how:

Boric acid;
Pyrethrum;
Pineronyl butoxide;
Other additives (affect the color and aroma of the drug).

Dust, when properly stored, retains all his abilities for more than five years. It is resistant to sudden changes in temperature, does not respond to direct ultraviolet rays.

Dust only afraid of high humidity. Getting into a humid environment, the powder becomes viscous and loses some of its properties.

Reference. In terms of its effectiveness in the fight against bedbugs, dust does not take a leading place, but it belongs to effective, proven and reliable means.

Operating principle

Dust can be like contact actions, and intestinal.

The preparation of intestinal action is not suitable for bedbugs. Bedbugs are blood-sucking insects, so the structure of their jaw and oral cavity as a whole are not intended for eating dry food. No matter how attractive dust is to bedbugs, they physically cannot eat it.

Advantages and disadvantages of using dust

Dust, like any drug, has its own strengths and weak sides, which are important to consider before proceeding with the persecution of bedbugs.

Advantages:

Ease of use (sold ready-made).
budget cost.
Low consumption (50 g is enough to process a room of 10 squares).
Long shelf life (up to 5 years).
A small dosage of insecticides, the drug is not toxic to humans.
A wide spectrum of action, can be used not only from bedbugs, but also from other insects (ants, cockroaches, fleas).

Disadvantages:

A low concentration of poison does not allow the drug to act instantly.
Harmless to larvae of bedbugs, destroys only adults and young individuals.
Re-treatment is required after 5-7 days.
Dust is categorically not recommended for use in rooms where children and pets can be. If ingested, it can cause intoxication and spasm of the respiratory system.

Dust from bedbugs. Instructions for use

Before proceeding with the persecution of bedbugs, the buyer should carefully read the instruction provided by the manufacturer. Although all types of dust preparations are used almost the same, sometimes there may be individual characteristics the use of one method or another.

Attention! To achieve the greatest effect, the use of dust from bedbugs dust should be carried out strictly according to the instructions attached to it.

Step-by-step algorithm of actions:

Training:

Remove bedding, bedspreads and pillows (they should be washed as hot water, not lower than 50 degrees, dry and iron on both sides).
Remove small items.
Take out food. An exception may be food stored in a refrigerator with a tight-fitting door.
Do not let children and animals into the room during processing and for another day after it.
It is mandatory for the person who will process the room to wear personal protective equipment - gloves for hands, a respirator, special goggles and outerwear.

Treatment:

In hard-to-reach places, the powder can be poured directly from the bag.
To treat accessible surfaces, a dry sponge is used, it is dipped into the powder and evenly distributed over all surfaces in the room: skirting boards, inner walls of cabinets, window sills from all sides, ventilation grilles. Be sure to carefully process upholstered furniture at the seams, on the back of the products and, if possible, on the internal parts.
The product is left on average for 4-10 hours (see instructions), after which the room can be ventilated and a wet general cleaning can be carried out. Hard to reach places you can not wash, but leave it as a prophylactic insect repellent.

finalthisup:

After processing the room, the person who performed this procedure needs to take a shower, wash their face, hair and hands well, and change clothes.
Wash clothes in hot water, personal protective equipment, discard after use.
Rags, sponges and napkins, after general cleaning, should also be disposed of or simply thrown away.

Attention! Dust is completely harmless to bug larvae, therefore, after the initial treatment of the premises, after 5-7 days, secondary treatment will be required. Failure to follow this recommendation will lead to re-infection of the premises.

Review:

I went on a business trip to Ryazan and rented the cheapest accommodation for a couple of weeks. I spent the whole day at work, I only came to the apartment to spend the night, so the comfort of rented housing did not bother me much. On the third day, I noticed strange small pimples that itched a lot, got scared, went to the doctor, it turned out to be bedbug bites. Somehow he survived his business trip in this ill-fated apartment and happily returned home. A week later, I discovered that I had brought bedbugs with me, so it was a complete surprise. They exhausted me so much on a business trip that I could not endure such a nightmare at home. I went to a hardware store and bought, on the advice of the seller, the Clean House product, applied it clearly according to the instructions, and was not too lazy to process the entire apartment twice. I was satisfied with the result, the bugs left immediately and for three months now I forgot about them. I can safely say that the dust helps against bedbugs.

There are many on the market today various means to fight bedbugs, not to mention folk methods. It is quite difficult to choose the optimal tool in which price and efficiency would be harmoniously combined. One thing is for sure: if there are a lot of bedbugs, and the room is large, then you need to use dust.

Indeed, bedbug dust is inexpensive, but effective tool quite convenient to use. There are a lot of manufacturers of dust, they are all equally effective, but here misapplication powder and ignorance of its main features can lead to not the best result.

Dust against bedbugs: what is this miracle remedy

As mentioned above, dust is a remedy for bedbugs, which is in powder form. The concentration of poison in the powder is usually low.

Poison has no smell. Dust has two ways of exposure: ingestion of a bug or contact exposure. The first option is impossible: in addition to blood, the bugs do not eat anything, which means that the poison will not enter their body from the outside through the intestinal tract.

Modern substances are quite safe for humans, and therefore can easily be used in residential areas. It is also worth paying attention to the fact that it is unprofitable to use powders in places with high humidity- they lose their poisonous properties.

You can buy a sachet of powder containing 50 g of the product at any household store or supermarket. One pack will cost up to 20 rubles, depending on the manufacturer, and it will be enough to process 10 meters.

Dust features: advantages and disadvantages

Before you buy any remedy for bedbugs, you need to weigh all its pros and cons. After all, the poison that helped one will not necessarily help others, because insecticides behave differently in different conditions. Powders are quite stable and behave the same in all situations, but sometimes they still fail.

Among the advantages of dust, the following should be highlighted:

instant effect upon contact with an insect;
wide spectrum of action;
low price of insecticide;
safety for people;
low concentration of poison;
long period of validity;
the possibility of using for prevention;
does not have a toxic odor.

Thanks to the advantages described above, it is very convenient to use dust in large rooms: the powder acts for a very long time, giving the bugs no chance to settle in a house or apartment. Also dust from bugs can be dissolved in water, creating a solution that can be sprayed various surfaces. After drying, the microparticles of the powder will be able to fall on the bugs and destroy them. It has dust and its drawbacks, among them an inconvenient method of application.

The difficulty of using the dust is that it is necessary to ensure that it gets on the insect, which is not always possible to do. For these purposes, it is much more convenient to use insecticides made in the form of aerosols, which make it easier to treat various surfaces. It is undesirable to use the powder in those homes where there are pets, because the powder can adversely affect animals.

The use of powder against bedbugs

Dust from bedbugs is used in the same way as all insecticides, because it has a method of action similar to them. Before you buy dust, you need to familiarize yourself with the rules for its use: they are not suitable for everyone.

You need to prepare an apartment in advance: wash everything thoroughly, pack food, personal hygiene items, clothes. Then you need to tightly close the windows and doors: the powder, although it is odorless, emits certain vapors, so it is better to keep the room closed. You need to dress as close as possible, be sure to use a protective mask, goggles and gloves.

You need to sprinkle the powder throughout the apartment. No need to pour it with slides: a thin, barely noticeable layer is enough. Particular attention should be paid to skirting boards, seams upholstered furniture, cabinets, walls behind furniture. It is important to find bedbug nests in advance and powder them. When cleaning the nesting of bedbugs, it is better not to touch it so that the insects do not scatter throughout the apartment.

It is not necessary to use dust in the form of a powder: you can dilute it in water, but keep a high concentration of the product.

Dust solution should be sprayed on all surfaces, especially those that are difficult to powder: walls, ceilings, furniture frame, polished cabinets and cabinets next to the bed. At the end of work, you need to leave the room for at least 5-6 hours. After you need to clean up, wiping all used surfaces and ventilate the room. There is no need to wash the powder from behind skirting boards, on walls and furniture frames. It is important to consider: the more powder closer to the bed, the better.
