This study estimates mercury and methylmercury levels in fish and fishery products commercialized in the city of Barcelona, Spain, from 2001 to 2007. Combining data of mercury levels in food with the consumption data of 2158 people (as the median of two 24-h recall), the total mercury intake of the Catalonian population was calculated. Mercury was detected in 32.8% of analysed samples. The general population average weekly intake of total mercury in the Catalonian population was 0.783 microg kg(-1) of body weight. This value is clearly lower than the Joint FAO/WHO Expert Committee on Food Additives (JECFA) provisional tolerable weekly intakes (PTWI) of 5 microg kg(-1) of body weight. The fish group was the main contributor to this value, mainly due to predatory species.
本研究评估了 2001 年至 2007 年期间在西班牙巴塞罗那市商业化的鱼类和渔产品中的汞和甲基汞含量。通过将食品中的汞含量数据与 2158 人的消费数据（作为两次 24 小时回忆的中位数）相结合，计算了加泰罗尼亚人口的总汞摄入量。在分析的样本中，检测到 32.8%的样本含有汞。加泰罗尼亚人口的总汞每周平均摄入量为 0.783 微克/千克体重。这一数值明显低于粮农组织/世卫组织食品添加剂联合专家委员会（JECFA）暂定每周耐受摄入量（PTWI）5 微克/千克体重。鱼类群体是造成这一数值的主要原因，主要是因为掠食性鱼类。
