Methods:In extraction method development,accelerated solvent extraction(ASE) method has been optimized to extract 7 OPPs including dichlorvos,dimethoate,monocrotophos,parathion-methyl,parathion,malathion,and chlorpyrifos in sea-sediment.

• 方法:用加速溶剂萃取仪(ASE)提取近海沉积物中的有机磷农药,用气相色谱-质谱(GC-MS)进行检测,建立了同时测定沉积物中敌敌畏、乐果、久效磷、甲基对硫磷、对硫磷、马拉硫磷、毒死蜱等7种有机磷农药的方法。
