What are the hazards of pesticides to people, and what are the hazards of pesticides

The harm of pesticides and insecticides to the human body is mainly manifested in three forms: acute poisoning, chronic harm and "three causes" hazards.

1. Acute poisoning.

Pesticides and insecticides enter the human body in large quantities through mouth, inhalation or contact, and the acute pathological reaction in a short period of time is acute poisoning. Acute poisoning often leads to nerve paralysis and even death, and even causes large-scale death, becoming the most obvious pesticide and insecticide harm.

2. Chronic hazards.

Long-term contact with or consumption of food containing pesticide residues can make pesticide and insecticide continue to accumulate in the body, posing a potential threat to human health, that is, chronic poisoning, which can affect the nervous system, destroy liver function, cause physiological disorders, affect the reproductive system, produce deformed freaks, and lead to cancer.

3. Carcinogenic, teratogenic and mutagenic.

The International Agency for Research on Cancer (IARC) has confirmed that 18 widely used pesticides and insecticides are significantly carcinogenic, and 16 have shown potential carcinogenic hazards. At present, although China has promulgated 5 batches of pesticide and insecticide safety use standards, and also stipulates that 10 types of pesticide insecticides are prohibited from being used in agriculture, they are useless and even intensified under the drive of interests. Among them, dibromochloropropane can cause male infertility and has carcinogenic and mutagenic effects on animals.

Tricyclotin and Tepdan have teratogenic effects on animals. Dibromoethane can cause teratogenicity and mutagenicity in humans and animals. Insecticides have a potential carcinogenic threat to humans and carcinogenic effects on animals.

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.

The harm of longan insecticide, the harm of longan insecticide, mainly manifests acute poisoning, a small number of poisoning, which is mainly due to the patient's one-time use or inhalation of a large number of pesticides and insecticides, acute poisoning will occur in a short time.
