摘要：

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. (C) 2014 Elsevier B.V.
