What are the effects of highly toxic pesticides on the air 5

Even if it is a low-toxicity insecticide, there is information to prove that if a person with a body weight of 60 kg may be poisoned and die as long as it is taken orally or absorbed by the gram, and the chronic toxicity of pesticides to humans can be carcinogenic and teratogenic. Therefore, consumers should be highly vigilant about the use of pesticides, and do not assume that everything will be fine without acute poisoning symptoms such as dizziness and nausea at that time.

There is also a class of insecticidal aerosols (commonly known as insecticidal water) and early emulsifiable concentrates on the market, which generally use benzene and its homologues with high toxicity as solutions, and long-term exposure to these auxiliaries will damage the hematopoietic system and even have the potential risk of inducing leukemia.

The use of pesticides should be used in strict accordance with the label of the insecticide bottle, most of the insecticides are written - after spraying the insecticide, leave the scene immediately, half an hour later, and wait until the doors and windows are opened to fully ventilate, before entering; Thirdly, infants, toddlers and children whose brain development is not yet complete should never be exposed to any insecticides, so as not to cause adverse effects on brain development. Also, never contaminate food and cooking utensils when using pesticides in the kitchen. Since most insecticidal aerosols use flammable odorless petroleum, benzene and their congeners as solvents, they have very low ignition points, so do not use them in kitchens with open flames and toilets with washing machines to avoid disasters.

There are very few particularly safe pesticides, but I have seen non-aerosol pesticides, which are not available in general pharmacies or supermarkets.

It's not harmful to the air, but it's harmful to people.

After all, pesticides are poisons, although they can only poison insects, but if they accumulate too much, they will definitely have an impact on the human body. Therefore, it is important to ventilate after each application of insecticide.

Pesticides are harmful to people.

Insecticides are mainly used to control agricultural pests and urban health pests, with a long history of use, large dosage and many varieties. In the twentieth century, with the rapid development of agriculture, pesticides led to a huge increase in agricultural production.

However, almost all pesticides can seriously alter ecosystems, be harmful to humans, and the rest will be concentrated in the food chain. There must be a balance between agricultural development and the environment and health. According to **, it can be divided into two categories: bio-derived pesticides and chemically synthesized pesticides.

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 organochlorines, organophosphorus and carbamates, are characterized by high efficiency and high or low residues, and many of them have high acute toxicity to mammals.
