| Popis: | Reproductive disorders in American alligators (Alligator mississippiensis) inhabiting Lake Apopka, Florida, have been observed for several years. Such disorders are hypothesised to be caused by endocrine disrupting contaminants occurring in the lake due to pesticide spills and runoff from bordering agricultural lands. Various studies have resulted in identification of several persistent chlorinated organic pollutants, some of them known endocrine disrupters, in various alligator tissues and fluids. In this report, livers from 12 juvenile alligators inhabiting Lake Apopka and 10 from Lake Woodruff, a control lake, were extracted and analysed using gas chromatography–mass spectrometry with chiral GC columns for identification of both chiral and non-chiral organochlorine pesticides (OCPs, including their metabolites); in so doing, the enantiomer fractions of any chiral OCPs identified were also measured. In Lake Apopka, p,p′-DDE was the most prominent OCP identified, being found in all samples at concentrati... |
