Chorio-allantoic membranes (CAMs) were collected and analyzed for chlorinated hydrocarbons as part of a wildlife toxicology demonstration project at Naval Air Station (NAS) Whidbey Island, Washington, USA. Concentrations of DDT, DDE, DDD, Aroclor 1254, and Aroclor 1260 were found at concentrations below 0.4 ppm for 13 of 14 samples. The low correlations among DDT and its metabolites in CAMs suggest herons are not being exposed to a consistent source of these compounds. Comparison of chlorinated hydrocarbon data for CAMs from three Puget Sound heron colonies, NAS Whidbey, Samish Island and Dumas Bay, indicates contaminant burdens in herons from NAS Whidbey and Samish Island are significantly lower than burdens in herons from Dumas Bay.
作为美国华盛顿州惠德比岛海军航空站（NAS）野生动物毒理学示范项目的一部分，收集了绒膜尿囊膜（CAMs）并对其中的氯代烃进行了分析。在14个样本中的13个样本中，滴滴涕（DDT）、滴滴伊（DDE）、滴滴滴（DDD）、多氯联苯混合物Aroclor 1254和Aroclor 1260的浓度均低于0.4 ppm。CAMs中DDT及其代谢物之间的低相关性表明，鹭类并未接触到这些化合物的持续来源。对普吉特海湾三个鹭类栖息地（惠德比岛海军航空站、萨米什岛和杜马斯湾）的CAMs氯代烃数据进行比较，结果表明，惠德比岛海军航空站和萨米什岛鹭类的污染物负担明显低于杜马斯湾鹭类的负担。
