摘要

摘要本研究报告了在印度金奈卡西梅度海岸捕获的16科海洋生物中总汞和甲基汞的浓度,这是一个重要的鱼类登陆区,但研究不足。其中包括常被捕获的黄花鱼、鲤鱼、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值(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,有些值高于筛选水平(总汞bbb40 μg/kg湿重)。缩写:dw:干重;MeHg:甲基汞;THg:总汞;Ww:湿重

Total and methyl mercury in small marine biota caught off the Coast of Chennai, India
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
