A very sensitive method using a direct mercury analyser was developed and validated according to the accuracy profile procedure to determine mercury levels in foods mainly consumed by infants and toddlers. Total mercury was not detected (LOD of 0.30µg.kg fresh weight) in 92.4% of the 291 food samples analysed or at relatively low concentrations, lesser than or equal to LB/UB 0.5/1.0µg.kg in all samples, except in fish samples (mean LB/UB 25µg.kg with a maximum of 53µg.kg). Levels of total mercury in these foods were in all cases within permitted Regulatory limits of 500 or 1000µg.kg in fishery products and muscle meat of fish.
开发了一种使用直接测汞仪的非常灵敏的方法，并根据准确度曲线程序进行了验证，以测定婴幼儿主要食用的食品中的汞含量。在分析的291份食品样本中，92.4%的样本未检测到总汞（鲜重的检测限为0.30μg/kg），或者总汞浓度相对较低，所有样本中均小于或等于LB/UB 0.5/1.0μg/kg，但鱼类样本除外（平均LB/UB为25μg/kg，最高为53μg/kg）。这些食品中的总汞含量在所有情况下均在渔业产品和鱼肉的500或1000μg/kg的法定允许限值范围内。
