We monitored the levels of 57 organic pollutants and 11 elements in the blood of 61 live stranded loggerhead sea turtles at the beginning and end of the rehabilitation period with the goal of evaluating whether recuperation of normal physiological conditions has an influence on the circulating levels of these pollutants from the blood. According to our results, several pollutants (OCPs, PCBs and toxic elements) are mobilized from storage tissues to the blood in sick turtles, and this is more evident in the subgroup of cachectic animals. We observed a significant decrease in the concentrations of some contaminants at the end of the rehabilitation period, probably due to redistribution processes. In contrast, an increase in the levels of the essential elements selenium and zinc was observed after a period of correct feeding and supplementation during hospitalization.
我们监测了 61 只在康复期间搁浅的红海龟血液中的 57 种有机污染物和 11 种元素的水平，目的是评估生理状况的恢复是否会影响这些污染物在血液中的循环水平。根据我们的研究结果，一些污染物（OCPs、PCBs 和有毒元素）会从储存组织中动员到患病海龟的血液中，在消瘦动物亚组中更为明显。我们观察到在康复期末期，一些污染物的浓度显著降低，这可能是由于再分配过程。相比之下，在住院期间经过正确的喂养和补充后，必需元素硒和锌的水平会升高。
