摘要
1979年4月在印度旁遮普省收集的所有成熟样品中均发现了滴滴涕和六氯环己烷残留的小麦颗粒和秸秆本底污染。小麦和秸秆中滴滴涕的平均残留量分别为0.03和0.05 mg kg - 1，六氯环己烷的平均残留量分别为0.04和0.06 mg kg - 1。分别。这种污染归因于这些杀虫剂在环境中无处不在，而不是故意使用。
Harvest time residues of DDT and HCH in the Punjab wheat crop untreated with these chemicals
The background contamination of wheat grains and straw with residues of DDT and HCH has been observed in all the samples collected at maturity from Punjab, India during April, 1979. The mean levels of DDT residues were 0.03 and 0.05 mg kg−1 in wheat grains and straw, respectively, while the corresponding levels of HCH were 0.04 and 0.06 mg kg−1,. respectively. This contamination has been ascribed to the ubiquitousness of these insecticides in the environment rather than to their deliberate usage.
