The present study determined the presence of heavy metals in green sea turtles with and without fibropapillomatosis in Itapirubá and Cassino beaches, southern Brazil. The weight, curved length of the carapace and body index were determined and blood was collected to quantify the concentrations of cadmium, lead and mercury. A total of 51 blood samples were analyzed, being 46 positives for at least one of the metals. There was a greater number of juvenile turtles in Itapirubá, larger in size and weight than those in Cassino. No statistical differences were found between metal concentrations between regions or between turtles with and without fibropapillomatosis. There was no significant correlation between metal concentrations, biometric variables and the presence of fibropapilomatose. Metal concentrations were low in both regions, with the highest concentrations being Cd and the lowest Hg.
本研究旨在确定巴西南部伊塔皮鲁巴和卡辛诺海滩患有和未患有纤维状乳头瘤病的绿海龟体内是否存在重金属。测量了海龟的体重、壳弯曲长度和身体指数，并采集血液以定量检测镉、铅和汞的浓度。共分析了 51 份血液样本，其中 46 份样本至少有一种金属呈阳性。伊塔皮鲁巴的幼龟数量较多，体型和体重均大于卡辛诺的幼龟。在地区之间或患有和未患有纤维状乳头瘤病的海龟之间，金属浓度没有统计学差异。金属浓度与生物计量变量和纤维状乳头瘤病的存在之间没有显著相关性。两个地区的金属浓度都较低，其中镉的浓度最高，汞的浓度最低。
