Fillets from a total of 1245 Northeast Atlantic mackerel (Scomber scombrus) sampled in different fishing areas of the Northeast Atlantic during 2007-2016 were analysed for mercury, cadmium, arsenic and lead using ICPMS. Mercury levels varied from <0.01 to 0.36 mg/kg wet weight (ww) with a total mean of 0.046 mg/kg ww and were significantly higher in Skagerrak than in the North Sea, the Norwegian Sea and west of Scotland. Cadmium concentrations varied from <0.002 to 0.16 mg/kg ww with a mean value of 0.015 mg/kg ww. Only 0.24 % and 0.16 % of the sampled fish exceeded the EU's maximum levels for cadmium and mercury, respectively. Arsenic levels varied between 0.43 and 6.9 mg/kg ww with a mean value of 2.2 mg/kg ww and showed seasonal variation following variations in fat content. Lead concentrations were low and below the analytical limit of quantification (LOQ) in 97 % of the samples.
2007-2016 年期间,在东北大西洋的不同捕捞区共采集了 1245 条东北大西洋鲭鱼(Scomber scombrus)样本,采用 ICPMS 对其体内的汞、镉、砷和铅进行了分析。汞含量范围为<0.01-0.36mg/kg 湿重(ww),总平均值为 0.046mg/kg ww,在斯卡格拉克显著高于北海、挪威海和苏格兰西部。镉浓度范围为<0.002-0.16mg/kg ww,平均值为 0.015mg/kg ww。只有 0.24%和 0.16%的抽样鱼超过了欧盟对镉和汞的最大限量。砷含量在 0.43-6.9mg/kg ww 之间,平均值为 2.2mg/kg ww,并随脂肪含量的变化呈现季节性变化。97%的样本中铅浓度较低,低于分析定量限(LOQ)。
