摘要
The investigation of organochlorine pesticides (OCPs) levels in sea turtles is an important issue in conservation research, due to the harmful effects of these chemicals. In the present study, OCPs concentrations were determined in the eggs of two sea turtle species (Eretmochelys imbricata and Chelonia mydas) collected from the Punta Xen and Isla Aguada (Mexican coast) in 2014 and 2015. Concentrations of 20 OCPs were analysed, including isomers of hexachlorocyclohexane, aldrin, chlordanes, endosulfans, methoxychlor, DDTs, and heptachlor. From the group of contaminants considered (analysed as families), the results revealed higher concentrations of ΣHCH and ΣDienes on both selected species. We analysed the relationship between turtle size and the OCPs concentrations; no correlation was found between the size of the female and concentrations in the eggs. In addition, principal component analysis indicated pattern differences between species and years, in good agreement with concentrations differences.

由于这些化学物质的有害影响，海龟中有机氯农药（OCPs）水平的调查是保护研究中的一个重要问题。在本研究中，在2014年和2015年从Punta Xen和Isla Aguada（墨西哥海岸）收集的两种海龟物种（Eretmochelys imbricata和Chelonia mydas）的卵中测定了OCP浓度。分析了20种OCP的浓度，包括异构体六氯环己烷，艾氏剂，氯丹，硫丹，甲氧滴滴涕，滴滴涕和七氯。从所考虑的污染物组（按家族分析），结果显示两种选定物种的ΣHCH和ΣDienes浓度较高。我们分析了龟大小与OCPs浓度之间的关系;雌性大小和蛋中浓度之间没有相关性。此外，主成分分析表明物种和年份之间的模式差异，与浓度差异很好地吻合。
