Pesticides enhance agricultural productivity, but the environmental and health side effects of their use justify government regulation, a subject of continuing societal debate. Bans on pesticide use are the principal regulatory device used in the United States. The economic impacts of such bans depend on the availability of substitutes, supply and trade conditions, and research and development. Without substitutes, pesticide bans result in reduced production levels and higher prices, a substantial loss of discretionary income to consumers, and a redistribution of income among agricultural producers. Most food safety concerns can be addressed by establishing standards and markets for pesticide-differentiated products, but worker safety and clean water concerns will require direct controls. Pesticide-use fees are shown to be more efficient than outright pesticide bans as a mechanism to obtain environmental goals. 相似文献

This paper reviewed management of pesticide residues in China including laws and regulations,the supervision system,the standard system,and the quality and safety of agricultural products. The process of establishment and internationalization of standards for pesticide residues were also discussed. Results indicate that the progress of the management of pesticide residues has been steadily made in China. However,the following aspects which refer to updates to regulations,supervising efficiency,standard system,risk assessment,international cooperation and communication,should be further improved. China should draw lessons from international experience,and then establish its own management system,which focuses on pesticides controls by strictly following relevant laws and technical standards to ensure the quality and safety of agricultural products. 相似文献
