六六六、二氯二苯基三氯乙烷及其代谢物二氯二苯基二氯乙烷及其代谢物二氯二苯基二氯乙烷在各种水生生物(软体动物、鱼类、鸟类和哺乳动物)中的α-，β和γ异构体及其代谢物二氯二苯基二氯乙烷在各种水生生物(软体动物、鱼类、鸟类和哺乳动物)中含有脂类(因为有机氯农药是亲脂性的)。该方法易于实施，经济上有利可图；它可以在没有特殊提取设备的实验室中使用，也可以在现场使用，只需最少的一套玻璃器皿和试剂。这一过程的结果是，通过使用正己烷更完整地提取与脂类化学结合的农药，以及减少提取和纯化具有浓硫酸的共挤压物质所需的步骤，提高了研究的效率和精确度。
Sample preparation can be used in biology and ecology for gas chromatographic determination of organochlorine pesticides (OCP), namely, α-, β- and γ-isomers of hexachlorocyclohexane (HCH), dichlorodiphenyltrichloroethane (DDT) and its metabolites dichlorodiphenyldichloroethane (DDD) and dichlorodiphenyldichloroethylene (DDE) in various aquatic organisms (molluscs, fish, birds and mammals) containing lipids (because organochlorine pesticides are lipophilic) in the internal organs and tissues, fat, skin and feather cover. The method is easy to implement and economically profitable; it can be used in laboratories without special extraction equipment, as well as in the field, with a minimum set of glassware and reagents. The result of this process is an increase of efficiency and precision of research through a more complete extraction of pesticides chemically bonded with lipids usingn-hexane and a reduction of the number of steps needed for the extraction and purification of co-extrusive substances with concentrated sulphuric acid.
