生态地球化学调查中的有机氯农药研究

Organochlorine pesticides in ecological geochemical survey

介绍了生态地球化学的概念和有机氯农药的生物有效性、环境介质中的残留、远距离迁移等性质。有机氯农药在环境中的有机地球化学行为,决定了在生态地球化学调查中必须采用特殊的采样方法、样品保存方法、稀疏的采样密度、多介质采样和分析技术。

The concept of ecological geochemistry and properties such as bioavailability, residues in environmental media and long-distance migration of organochlorine pesticides are introduced in this paper. The special methods of sampling and sample preservation, low sampling density, multi-media sampling and analytical technique for samples must be adopted in ecological geochemical survey according to organic geochemical behaviors of organochlorine pesticides in the environment.
