摘要
当前国际上已商品化的农药多达1300多种,国内使用的亦有数百种。这些农药使用后,通过降雨灌溉进入江河,形成水体多农药污染。目前世界上许多国家都在研究多农药污染的监测技术。
A method for determining multiresidue of organo-chlorine, organophosphorus and carbamate pesticides is presented. After being extracted as a whole with mixed polar and nonpolar solvents, the organophosphorus and carbamate residues were separated on OV-1 stationary phase under temperature programming and organochlorine residues on OV-17+QF-1. Recoveries ranged from 81. 4 % to 104%,MDQ from 10-10 to 10-14g,and MDC from 10-2 to 10-3mg/L.
