摘要
从暴露途径来看,食物是人体砷暴露的主要途径之一。从饮食结构来看,广州市居民膳食主要来源于谷类食品,同时鱼虾类总体平均摄入量约为全国总体平均摄入量的2倍。因此,在分析广州市市场大米和海鲜这2种典型食品中砷含量的基础上对广州市居民食品砷摄入的健康风险进行了评价。分析了广州市场上的26种不同品牌的大米中的总砷含量,其含量范围为0.082～0.171μg·g^(-1),平均浓度为(0.127±0.027)μg·g^(-1),满足绿色食品大米标准(≤0.40μg·g^(-1))。在14种鱼虾蟹贝类海鲜中的砷含量分析基础上,计算得出广州市场上鱼类中总砷的平均含量为0.488μg·g^(-1),虾蟹贝类中总砷的平均含量为3.44μg·g^(-1),相比较国内外,广州市场鱼虾蟹中砷的含量整体处于中间水平。最后综合文献调研中其他主要食品中砷的含量,计算得出广州市成人通过食品每日摄入总砷的量为5.08μg·kg^(-1)BW·d^(-1)。建议日常饮食需要特别控制每日海鲜的摄入量,尤其是砷含量较高的濑尿虾、红虾及红蟹、花蟹。
Food,especially rice and seafood,is the major pathway of people exposure to arsenic in Guangzhou,China.In order to evaluate human health risk of arsenic from food in this area,26 samples of rice and 14 of seafood were purchased randomly from the markets and total arsenic concentrations of them were analyzed.Our results showed that the concentrations of arsenic in different rice were in the range of 0.082-0.171 μg·g^-1 and the average was（0.127±0.027） μg·g^-1.Meanwhile,arsenic concentrations in fish and other seafood were 0.488 μg·g^-1 and 3.44 μg·g^-1,respectively.In addition,arsenic in other food in Guangzhou City was also investigated based on data collection from references.By combining data from references with our research results,daily arsenic intake through food by adults in Guangzhou was calculated to be 5.08 μg·kg^-1 body weight·d^-1.As a result,more attention should be paid regarding seafood intake in Guangzhou market,especially mantis shrimp,red shrimp,red crab and spotted crab.
