食品伙伴網(wǎng)訊   據(jù)外媒報(bào)道，研究人員說(shuō)，由于海水受到污染，夏威夷黃鰭金槍魚(yú)體內(nèi)汞含量升高，每年增加3.8%以上。

    燒煤的電廠和人工開(kāi)采金礦作業(yè)會(huì)產(chǎn)生汞。具有強(qiáng)烈毒性的汞會(huì)流入世界各地的水中，對(duì)吃某些魚(yú)類的民眾構(gòu)成健康風(fēng)險(xiǎn)。科學(xué)家預(yù)計(jì)魚(yú)類體內(nèi)汞含量將升高，這是空氣污染因工業(yè)化而加劇的結(jié)果，但很難找到證據(jù)。

    部分原文報(bào)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.
