Because of their vulnerable population status, assessing exposure levels and impacts of toxicants on the health status of Gulf of Mexico marine turtle populations is essential, and this study was aimed to obtain baseline information on oxidative stress indicators in hawksbill sea turtle (Eretmochelys imbricata). In order to evaluate the health status of sea turtles and the effect of organochlorine compounds (OC) in the southern part of the Gulf of Mexico, we searched for relationships between carapace size and the activity of antioxidant enzymes in the blood of the hawksbill sea turtle. The level of oxidative stress biomarkers such as the enzymes catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), glutathione S-transferase (GST), and acetylcholinesterase (Ache) in the hawksbill sea turtle was analysed during nesting season in the years 2014-2015 at Punta Xen (Campeche, Mexico). The results of this study provide insight into data of antioxidant enzyme activities in relation to contaminant OCPs in hawksbill sea turtles and the possible health impacts of contaminant in sea turtles.
由于其脆弱的种群状况，评估有毒物质对墨西哥湾海洋龟类种群健康状况的暴露水平和影响至关重要，本研究旨在获得玳瑁（Eretmochelys imbricata）氧化应激指标的基线信息。为了评估海龟的健康状况和墨西哥湾南部有机氯化合物（OC）的影响，我们研究了龟壳大小与玳瑁血液中抗氧化酶活性之间的关系。在 2014-2015 年的筑巢季节，我们在坎佩切的 Xen 角（Punta Xen）分析了玳瑁体内的氧化应激生物标志物水平，如过氧化氢酶（CAT）、超氧化物歧化酶（SOD）、谷胱甘肽还原酶（GR）、谷胱甘肽 S-转移酶（GST）和乙酰胆碱酯酶（Ache）等酶的活性。本研究的结果为了解玳瑁体内抗氧化酶活性与污染物 OCPs 的关系以及污染物对海龟健康的可能影响提供了数据。
