Pesticide harm to human body and protective measures

Summer is the season when crops, vegetables, and fruit trees are vulnerable to pests. It is also a season when farmers spray pesticides in large quantities. However, due to the excessive exposure of skin and limbs, and the pores open, farmers are more likely to breathe and suspend airborne pesticides when farmers spray pesticides. Pesticide particles penetrate through the skin and cause poisoning.

First, the harm of spraying pesticide on human body can be divided into acute poisoning, chronic hazard and "three causes" three levels of harm.

Acute poisoning
Pesticides enter the body in large quantities through the mouth, inhalation channels, or contact, and the acute pathological reactions that appear in a short period of time are acute poisoning. Acute poisoning often causes a large number of individual deaths and becomes the most obvious pesticide hazard.

2. Chronic hazard
Long-term exposure or consumption of food containing pesticides can cause pesticides to continuously accumulate in the body, posing a potential threat to human health. Pesticides continue to accumulate in the human body. Although they do not cause obvious symptoms of acute poisoning within a short period of time, they can cause chronic hazards that can damage the normal function of the nervous system. Although the chronic hazard of pesticides can not directly endanger human life, but it can reduce human immunity, thus affecting human health, resulting in the occurrence of disease.

3. Carcinogenic, teratogenic, mutagenic
At present, China has issued five batches of pesticide safety use standards, which stipulate that 10 pesticides are prohibited from being used in agriculture. These include dibromochloropropane (can cause cancer), dibromoethane (causing animal or human malformation), insecticidal warts on humans have a potential carcinogenic threat, and have carcinogenic effects on animals.

Second, the way to spray pesticides to cause poisoning is mainly through the respiratory tract and skin penetration.

1. Respiratory tract: When spraying and fumigating pesticides, or using some volatile pesticides, they can be inhaled into the human body through the respiratory tract. Larger diameter pesticide particles cannot enter the lungs directly and are trapped in the nose, mouth, throat, or trachea and are absorbed by these surface mucous membranes; only pesticide particles with a diameter of 1 to 8 microns can enter the lungs directly and are Quickly and completely absorb the entry body
2. Skin penetration: For the production and use of pesticides, absorption through the skin is the most common route of entry into the human body. Most of the pesticides can be absorbed through intact skin, and no traces are left on the skin surface after absorption. Therefore, skin absorption is usually the most easily overlooked method. When the skin has a wound, its absorption is significantly greater than that of the intact skin. Pesticide preparations are liquids or oils, and concentrated formulations have faster skin absorption.

Third, spraying pesticides should do the following protective measures:

In order to avoid and reduce the occurrence of pesticide poisoning due to spraying pesticides, during the process of dispensing or spraying, try to avoid spraying under high temperature at noon. To wear long-sleeved pants, you must wear necessary protective equipment, such as anti-virus masks. Clothing, anti-chemical gloves. In the process of spraying pesticides, try not to eat, drink or smoke. Spray pesticides should stand on the position of the uptake, and do not shuttle between crops that have been given pesticides.

Do not use the mouth to blow blocked contacts. Use toothpicks or straws or who can clear them. Do not apply for more than 6 hours per day. Clean personal hygiene after application, change clothes in time, and wash your face with cold or warm soap. Wash the exposed parts of the hands and face and the liquid on the protector in time.

Finally, to remind the majority of farmers friends, pesticide use must do a good job protective measures, including personal protection work during the spraying of pesticides. When spraying high-concentration toxic pesticides, be sure to maintain high vigilance. If you find difficulty in breathing, vomiting, dizziness, and weakness, immediately move away from the area where the pesticide is sprayed and rest at the windward position. In serious cases, you must promptly seek medical attention.
