食品伙伴网讯 据外媒报道,研究人员说,由于海水受到污染,夏威夷黄鳍金枪鱼体内汞含量升高,每年增加3.8%以上。
烧煤的电厂和人工开采金矿作业会产生汞。具有强烈毒性的汞会流入世界各地的水中,对吃某些鱼类的民众构成健康风险。科学家预计鱼类体内汞含量将升高,这是空气污染因工业化而加剧的结果,但很难找到证据。
部分原文报道如下:
mercury concentrations in Hawaiian yellowfin tuna are increasing at a rate of 3.8 percent or more per year, according to a new University of Michigan-led study that suggests rising atmospheric levels of the toxin are to blame.
Mercury is a potent toxin that can accumulate to high concentrations in fish, posing a health risk to people who eat large, predatory marine fish such as swordfish and tuna. In the open ocean, the principal source of mercury is atmospheric deposition from human activities, especially emissions from coal-fired power plants and artisanal gold mining.
