[0002] At present, chemical pesticides have caused extremely serious harm to humans and other organisms, posed a huge threat to biodiversity, and caused incalculable and irreversible negative impacts on humans and nature.

However, my country is a big country in the production and use of pesticides in the world, and mainly uses chemical pesticides, resulting in the residues of pesticides in soil, water, food, vegetables, and fruits in many areas greatly exceeding national safety standards, which is harmful to the environment, organisms, and human body. Health poses a serious threat. For humans, chemical pesticides accumulate continuously in the body. Although they will not cause obvious acute poisoning symptoms in a short period of time, they can cause chronic harm. Although the chronic harm of chemical pesticides cannot directly endanger human life, it can It can reduce human immunity, thereby affecting human health, leading to an increase in the prevalence of other diseases (such as: carcinogenic, teratogenic, mutagenic) and mortality
