Abstract: Pesticides are widely produced and used in China. The hazardous wastes of pesticide industry has attracted extensive attention of the public and managers due to its large output, high toxicity and difficulty in disposal. The combing and clarification of the generation sources, pollution characteristics, and environmental risk key nodes of hazardous wastes in pesticide industry plays an important supporting role in the management of hazardous wastes in pesticide industry in China. Mother liquor, waste acid, waste salt and sludge are several types of hazardous wastes with the largest production in pesticide industry. There are many kinds of pollutants contained in hazardous wastes of pesticide industry, mainly including reaction raw material residues, side reaction products and effective components of pesticide. At present, the key environmental risk in the treatment and disposal of pesticide hazardous wastes lies in the utilization of by-products of pesticide industry. In view of the problems existing in the process of utilization and disposal, it was suggested that the ecological environment management department formulate perfect pollution control standards, adopt targeted policies, encourage and guide enterprises to develop advanced processes, carry out source reduction, improve the level of resource utilization, and comprehensively improve the level of environmental risk prevention and control of solid wastes in pesticide industry.
