Total and toxic (sum of As(III), As(V), monomethylarsenic (MMA), and dimethylarsenic (DMA)) As concentrations were assessed in 19 respectively 4 different fish and shellfish species from the North Sea. Following results were obtained: (i) for fish an average total As concentration of 12.8 microg/g ww and a P90 value of 30.6 microg/g ww; (ii) for shellfish an average total As concentration of 21.6 microg/g ww and a P90 value of 40.0 microg/g ww; (iii) for fish an average toxic As concentration of 0.132 microg/g ww and a P90 value of 0.232 microg/g ww; (iv) for shellfish an average toxic As concentration of 0.198 microg/g ww and a P90 value of 0.263 microg/g ww. For the Belgian consumer the average daily intake of total arsenic from fish, shellfish, fruit, and soft drinks (the main food carriers of As in Belgium) amounts to 285 microg/day with more than 95% coming from fish and shellfish, while for a high level consumer it amounts to 649 microg/day, more than twice the average value. Using the same daily consumption pattern for the selected food products as for total As, we find that the average daily intake of toxic As amounts to 5.8 microg/day, with a 50% contribution of fish and shellfish and the high level intake to 9.5 microg/day. When considering the FOA/WHO Expert Committee's recommendation for inorganic As intake of 2 microg/kg bw/day or 140 microg/day for a 70 kg person, the toxic dose in Belgium is thus an order of magnitude lower.
对北海的19种和4种不同鱼类及贝类中的总砷以及有毒砷（砷（III）、砷（V）、一甲基砷（MMA）和二甲基砷（DMA）的总和）浓度进行了评估。得到以下结果：（i）对于鱼类，总砷平均浓度为12.8微克/克湿重，P90值为30.6微克/克湿重；（ii）对于贝类，总砷平均浓度为21.6微克/克湿重，P90值为40.0微克/克湿重；（iii）对于鱼类，有毒砷平均浓度为0.132微克/克湿重，P90值为0.232微克/克湿重；（iv）对于贝类，有毒砷平均浓度为0.198微克/克湿重，P90值为0.263微克/克湿重。对比利时消费者而言，鱼类、贝类、水果和软饮料（比利时砷的主要食物载体）中总砷的平均每日摄入量为285微克/天，其中95%以上来自鱼类和贝类，而对于高摄入量消费者，该值为649微克/天，是平均值的两倍多。使用与总砷相同的所选食品每日消费模式，我们发现有毒砷的平均每日摄入量为5.8微克/天，其中鱼类和贝类贡献了50%，高摄入量为9.5微克/天。考虑到粮农组织/世卫组织专家委员会关于无机砷摄入量的建议，即2微克/千克体重/天或对于70千克的人而言为140微克/天，比利时的有毒剂量因此低一个数量级。
