Abstract：
The present study determined if green sea turtles (Chelonia mydas) in Kailua Bay, Oahu, in the Hawaiian Islands have elevated blood and scute lead (Pb), arsenic (As), and antimony (Sb) concentrations resulting from lead deposition at a historic skeet shooting range. Blood and scute samples were collected and analyzed for Pb, As, and Sb via inductively coupled plasma-mass spectrometry. Prey, water, and sediment samples were also analyzed. Turtle samples in Kailua Bay (45) have blood Pb concentrations (328 ± 195 ng/g) greater than a reference population (Howick Group of Islands, 29.2 ± 17.1 ng/g). Compared with other green turtle populations, only turtles in Oman, Brazil, and San Diego, CA have blood Pb concentrations greater than turtles in Kailua Bay. The estimated daily exposure of Pb from algae sources in Kailua Bay (0.12 mg/kg/day) was significantly lower than the no observed adverse effect level (100 mg/kg) of red-eared slider turtles. However, the chronic effects of Pb on sea turtles is poorly understood and continued monitoring of this population will increase our understanding of the Pb and As loads of sea turtles in Kailua Bay.

摘要：
本研究确定了凯鲁阿湾的绿海龟（Cheloniamydas），瓦胡岛,夏威夷群岛的血液和铅（Pb）升高，砷（As），和历史飞碟射击场上铅沉积产生的锑（Sb）浓度。收集血液和粪便样本并分析铅，As,和Sb通过电感耦合等离子体质谱法。猎物,水,和沉积物样品也进行了分析。凯鲁阿湾（45）的海龟样本的血液铅浓度（328±195ng/g）高于参考种群（Howick群岛，29.2±17.1ng/g)。与其他绿龟种群相比，阿曼只有海龟,巴西,还有圣地亚哥,CA的血液铅浓度高于开鲁亚湾的海龟。凯鲁亚湾藻类来源的铅的估计每日暴露量（0.12mg/kg/天）显着低于未观察到的红耳滑龟的不利影响水平（100mg/kg）。然而,人们对铅对海龟的长期影响知之甚少，对该种群的持续监测将增加我们对凯鲁亚湾海龟的铅和砷负荷的了解。环境毒物化学2023；00：1-15。©2023SETAC。本文由美国政府雇员贡献，他们的工作在美国的公共领域。
