How can there be non toxic pesticides, and are odorless pesticides toxic

Every summer, insecticide advertisements are overwhelming, and from time to time you see words and phrases such as "environmentally friendly products are fragrant and pleasant", "harmless to humans and animals", and the poisons specially used to kill insects are not toxic to humans and animals! To date, no insecticide that is non-toxic to humans and animals has been developed in the world. The toxicity of pesticides to humans is acute and chronic.

Even micro-toxic insecticides are highly toxic to humans and animals. The chronic toxicity of pesticides to humans is comprehensively evaluated by a series of biological tests such as carcinogenicity, teratogenicity, mutagenicity, reproduction and delayed neurotoxicity. Don't think that everything will be fine without dizziness, vomiting and other acute poisoning symptoms, its impact on the human body will take a long time to be revealed.

Even pyrethroid insecticides, which are currently recognized as safe in countries around the world, are also significantly toxic to the body's nervous system, and long-term exposure, even in low doses, can cause nerve paralysis, paresthesia, dizziness and headache and other neurological symptoms. As for those pesticides that belong to organophosphorus, organochlorine and carbamates, they are even more toxic to humans and animals. Not only that, some insecticidal aerosols, insecticidal emulsions, etc., also use more toxic benzene and its homologues as solvents, and long-term human contact will damage the hematopoietic system.

These solvents have the potential to induce leukemia and bone marrow suppression, and it is no wonder that the number of leukemia patients has increased in recent years. Pay attention to the use of insecticides at home: 1. Try to use pesticides sparingly, or replace them with Chinese herbal medicines that have been used by our ancestors for a long time.

2. Do not stay in the house where the medicine has been applied, leave immediately after the application of the medicine, and open the doors and windows after an hour and a half to fully ventilate and exhaust before entering. 3. Infants and children should not be exposed to any pesticides to avoid adverse effects on brain development. 4. After applying pesticides, wash your hands, bathe, and change your clothes.

5. Mosquito coils, mosquito control tablets, cockroach control tablets, etc., are regarded as insecticides. How do I shop for insecticides? 1. Pyrethroid insecticides are safer, and the safety of organochlorine, organophosphorus and carbamate is worse than the former; Among the various pyrethroid insecticides, permethrin, methrin, allethrin and deltamethrin are safer.

Second, the insecticides that are expressly prohibited from being used include mirex, DDT, toxaphene, chlordane, heptachlor, naphthalene, etc.; Prohibited rodenticides include fluoroacetamide, rat die, rat silicone, and sodium fluoroacetate.

Nano mineral oil is a completely non-toxic insecticide and fungicide, the principle of insecticide and sterilization is suffocation, dissolution, isolation, belongs to mineral pesticides, allowed to be used in organic planting, more stable and effective than biological pesticides, insecticide than toxic pesticides almost can not be touched to kill, but the sterilization effect is far more than ordinary toxic fungicides. The key is that one dose and two uses can save a lot of labor costs.

In fact, there is a pesticide in Japan that does not use toxic chemical raw materials. The principle is a freeze spray, spray at visible mosquitoes, and they will be frozen immediately. Although theoretically non-toxic, it is also very dangerous to use, and spraying people is not a joke.

And it does not have a large killing area, so it cannot have an effect on cockroaches hiding in nests.

Although some pesticides on the market are labeled as "odorless" or "non-toxic", this does not mean that they are absolutely safe. The components of pesticides mostly contain heavy metal elements such as cadmium, lead, arsenic, and poisons such as organochlorine and benzene. Moreover, no matter how pesticides are applied, they will cause a certain degree of environmental pollution, and volatile particles and fog droplets are more likely to remain on walls, floors, furniture, clothing, and pass through the respiratory tract.

Inhalation or ** contact.

The use of pesticides has gone through several stages: the first to be discovered are natural pesticides and inorganic compounds.

But they do a single job.

1. Large dosage and short duration of effect; Organochlorine, organophosphorus and carbamate are organosynthetic insecticides, which are characterized by high or low residue efficiency, and there are many varieties of mammals.

There is a high degree of acute toxicity.

Colorless and odorless pesticides are not necessarily toxic or non-toxic, and the main thing to look at is the ingredient formula list.

Some.

Many families use all kinds of aerosol insecticides, insecticidal emulsifiable concentrates, mosquito tablets, mosquito coils and cockroach tablets, etc., most of which use pyrethroid deltamethrin as the active ingredient of insecticide. Although manufacturers label the packaging with the words "harmless to humans and birds", in fact, its insecticidal ingredients are not only toxic to humans, but also auxiliary ingredients are also harmful to humans.

If it is used every day, and the doors and windows are closed when using, it is easy to inhale the organic solvent aerosol of the insecticide into the body, and long-term excessive inhalation will damage the liver, kidneys, nervous system, and hematopoietic system of the person. Especially in children, the consequences are even more severe.

After spraying insecticide, people should leave immediately, it is best to open the doors and windows after an hour and a half to fully ventilate and exhaust before entering, and do not use insecticide in the child's room.

Insecticide refers to a drug that kills pests, such as beetles, flies, grubs, nose worms, jumping worms and nearly 10,000 other pests.

The use of pesticides has gone through several stages: the first to be discovered are natural pesticides and inorganic compounds, but they have a single effect.

1. Large dosage and short duration of effect; Organosynthetic insecticides such as organochlorine, organophosphorus and carbamate are characterized by high efficiency and high or low residues, and many of them have high acute detoxification to mammals.
