Abstract:
This study reports OCP and PAH concentrations in the tissues of stranded sea snakes from Sharjah, UAE. Samples from 10 Hydrophis lapemoides, 2 Hydrophis ornatus and 1 Hydrophis curtus were analyzed. Muscle, liver and fat tissues were extracted using micro-QuEChERs, followed by d-SPE and analyzed using GC/MS. Higher concentrations of OCPs were detected, while PAHs were more frequently detected. Significant correlations suggest that OCPs and PAHs do bioaccumulate in the tissues of sea snakes. Additionally, OCPs with lower log Kow (octanol-water partition coefficient) values were mainly detected in the muscle samples of H. lapemoides, whereas OCPs with higher log Kow values were more commonly present in the liver and fat samples. The concentrations of OCPs reported in this study were higher than those previously documented in other marine reptiles in the UAE or sea snakes from different geographical regions.
摘要:
这项研究报告了沙迦搁浅海蛇组织中的OCP和PAH浓度,阿联酋。来自10个苦参素的样品,分析了2口水和1口水。肌肉,使用微型QuEChER提取肝脏和脂肪组织,然后是d-SPE,并使用GC/MS进行分析。检测到较高浓度的OCPs,而PAHs的检测频率更高。显着的相关性表明OCP和PAHs确实在海蛇的组织中生物积累。此外,具有较低logKow(辛醇-水分配系数)值的OCP主要在H.lapemoides的肌肉样品中检测到,而具有较高logKow值的OCP更常见于肝脏和脂肪样本中。这项研究中报告的OCP浓度高于先前在阿联酋其他海洋爬行动物或来自不同地理区域的海蛇中记录的浓度。
