摘要：

We determined total mercury (Hg) distribution in muscle and liver of ten ray species and assessed health risk considering Hg levels in muscle and average consumption of rays in Mexico. Rays were collected from five sites in NW Mexico between March and November 2012. Hg concentrations ranged from 4.465 mu g g(-1) in muscle of the longtail stingray Dasyatis longa to 0.036 mu g g(-1) in liver of the diamond stingray Dasyatis dipterura. Considering all the individuals, Hg in muscle (1.612 +/- 1.322 mu g g(-1)) was significantly (p < 0.05) higher than in liver (0.745 +/- 0.616 mu g g(-1)). Regarding local health risk assessment, none of the ray species may cause adverse effects on consumers. (C) 2013 Elsevier Ltd. All rights reserved.
