OBJECTIVES
The aim of the study was to characterize the risk for elevated mercury (Hg) from fish consumption among Asians in Chicago. Consumption of fish contaminated with methyl Hg (MeHg) can affect the neurodevelopment in children and cardiovascular disease risk in adults.
METHODS
We collected fish consumption information and hair samples for Hg at two health fairs. We purchased fish from Asian fish markets.
RESULTS
Geometric mean hair Hg from 71 participants was 0.58 μg/g, with 28% overall and 29% of women of childbearing age having hair Hg levels at least 1 μg/g; 20% ate fish 4 or more times/wk. Tuna consumption and non-Chinese Asian ethnicity were associated with elevated Hg. Hg levels in purchased fish were generally low.
CONCLUSIONS
Our study confirms other findings that, compared with estimates of the general US population, Asians are at higher risk of elevated MeHg because of frequent fish consumption.
目的
本研究旨在描述芝加哥亚洲人因食用鱼类导致汞（Hg）含量升高的风险。食用受甲基汞（MeHg）污染的鱼类会影响儿童的神经发育以及成年人患心血管疾病的风险。
方法
我们在两次健康博览会上收集了鱼类食用信息和用于检测汞含量的头发样本。我们从亚洲鱼市购买鱼类。
结果
71名参与者头发汞含量的几何平均值为0.58μg/g，总体上28%的人以及29%的育龄妇女头发汞含量至少为1μg/g；20%的人每周吃鱼4次或更多次。食用金枪鱼和非华裔亚洲族裔与汞含量升高有关。购买的鱼类中的汞含量普遍较低。
结论
我们的研究证实了其他研究结果，即与美国普通人群的估计值相比，亚洲人因频繁食用鱼类而面临更高的甲基汞含量升高风险。
