Abstract This study reports the concentrations of total mercury and methyl mercury in sixteen families of marine biota caught off the coast of Kasimedu in Chennai, India, an important but understudied fish landing region. These included the commonly caught croakers, carangids, rays, goat fish, anchovies, crabs, and prawns. There was no correlation between total mercury or methyl mercury with fish length or mass. All concentrations were lower than the Food Safety and Standards Authority of India limits (total mercury = 500 μg/kg; methyl mercury = 250 μg/kg). Some values were above screening levels (total mercury >40 μg/kg wet weight) when considering possible adverse effects in predatory fish that consume the analyzed biota. Abbreviations: dw: dry weight; MeHg: methyl mercury; THg: total mercury; ww: wet weight

在印度钦奈海岸捕获的小型海洋生物群中的总汞和甲基汞
摘要 本研究报告了在印度钦奈 Kasimedu 海岸捕获的 16 个海洋生物群中的总汞和甲基汞浓度,这是一个重要但尚未得到充分研究的鱼类登陆区。这些包括常见的黄鱼、carangids、鳐鱼、山羊鱼、凤尾鱼、螃蟹和对虾。总汞或甲基汞与鱼的长度或质量之间没有相关性。所有浓度均低于印度食品安全和标准局的限制(总汞 = 500 μg/kg;甲基汞 = 250 μg/kg)。考虑到对食用所分析生物群的掠食性鱼类可能产生的不利影响,一些值高于筛选水平(总汞 >40 微克/千克湿重)。缩写:dw:干重;MeHg:甲基汞;THg:总汞;ww:湿重
