This short note aims to report in detail a preliminary assessment of the concentrations of Cd, Hg and Pb in tissues of blue crabs Callinectes danae collected from the Cananéia-Iguape-Peruíbe estuarine complex (CIP), in the South of São Paulo State coast, Brazil. In October 2014, blue crabs were collected from CIP. Tissues were removed by dissection and metal determination was performed by GF-AAS and CV-AAS. According to statistical analysis, Pb and Cd concentrations in gills were significantly higher than those found in muscles and hepatopancreas, respectively. There were no significant differences in Hg concentrations between samples. Cd, Hg and Pb concentrations in gills and hepatopancreas were lower than those reported in a previous study performed at CIP. However, Cd concentration in hepatopancreas was higher than the Brazilian limit for consumption and new efforts to monitor Cd concentrations in C. danae tissues must be performed.
本短笺旨在详细报告对巴西南圣保罗马里尼奥州海岸坎内尼亚-伊瓜佩-秘鲁河口综合区（CIP）所采集的蓝蟹 Callinectes danae 组织中 Cd、Hg 和 Pb 浓度的初步评估结果。2014 年 10 月，在 CIP 采集了蓝蟹。通过解剖取出组织，并采用石墨炉原子吸收光谱法（GF-AAS）和火焰原子吸收光谱法（CV-AAS）进行金属测定。根据统计分析，鳃中的 Pb 和 Cd 浓度明显高于肌肉和肝胰腺中的浓度。Hg 浓度在样本间无显著差异。鳃和肝胰腺中的 Cd、Hg 和 Pb 浓度低于之前在 CIP 进行的研究报告的值。然而，肝胰腺中的 Cd 浓度高于巴西的食用限量，因此必须对 C. danae 组织中的 Cd 浓度进行新的监测。
