农药对人体健康及生态环境的影响

Effects of Pesticides on Human Health and Ecological Environment

随着世界人口的不断增长以及人类对生活品质要求的不断提升,粮食安全与生态健康是在全球环境逐步恶化的现实中所必须面临,同时又必须用新的科技手段不断加以改善和提高的一个挑战。从20世纪40年代至今,化学农药在农业生产中的大量应用,为保证世界的粮食安全作出了巨大贡献,同时,也给人类赖以生存的生态环境带来了不可避免且日益加深的危害,进而也严重影响了人体健康。为了既保证粮食安全,又保持生态健康,科研工作者已研制出多种与化学农药功能相似的生物农药。主要叙述了使用化学农药为人类粮食安全所作出的贡献以及对生态环境和人体健康所产生的危害,生物农药的发展现状、特点和发展前景。

With the continuous growth of the world population and the continuous improvement of human life quality requirements,food security and eco-environment health are a challenge that we must face in the reality of the gradual deterioration of the global environment,and meanwhile,we must constantly improve and enhance them by means of new scientific technologies.Since the 1940s,the application of chemical pesticides in agricultural production has made a great contribution to ensuring the world’s food security,however,it has also brought inevitable and deepening harm to the eco-environment that human beings depend on,which has then seriously affected human health.In order to guarantee the food security and maintain the eco-environment health,researchers have developed a variety of biological pesticides which are similar in functions to chemical pesticides.This article mainly described the contribution of the use of chemical pesticides to human food security,the harm to the ecological environment and human health,the development status,characteristics and development prospects of biological pesticides.
