Abstract

Pesticides are an important means to ensure agricultural harvest. Their long-term repeated use leads to a large number of residues in the farmland environment, while pesticides left in soil and water are easy to migrate to non target crops, further affecting plant physiological metabolism and rhizosphere environment. This paper mainly studied the acute toxicity of pesticides to environmental organisms and the safety evaluation of fish. This paper first analyzes the impact of environmental pollutants on plants, explores several commonly used pesticide detection technologies, and preliminarily evaluates the ecological risk caused by pesticide residues in river surface water and farmland soil according to the risk assessment method recommended by USEPA. According to the evaluation results, the pesticide residues in the rivers and soils of cities a and B selected in this paper meet the safety standards.
