The arsenic content in 255 samples of plaice (Pleuronectes platessa) varied between 3 and 166 mg/kg. About 65% of the samples had an arsenic content above 10 mg/kg. High (low) arsenic concentration in the fillet corresponds with a high (low) concentration in milt or roe. An excretion experiment with eight human volunteers showed that after the consumption of plaice, 69-85% of the ingested arsenic was excreted in the urine within five days. The organo-arsenic compound present in plaice was isolated by means of extraction, ion-exchange and thin-layer chromatography. Field desorption mass spectrometry of the isolate showed that arsenic was present as arsenobetaine, (CH3)3AsCH2C00-.
255份鲽鱼(欧洲鲽)样本中的砷含量在3至166毫克/千克之间。约65%的样本砷含量高于10毫克/千克。鱼肉中高(低)砷浓度与精液或鱼卵中的高(低)浓度相对应。一项针对8名人类志愿者的排泄实验表明,食用鲽鱼后,5天内摄入砷的69 - 85%通过尿液排出。通过萃取、离子交换和薄层色谱法分离出鲽鱼中存在的有机砷化合物。对分离物进行场解吸质谱分析表明,砷以砷甜菜碱((CH3)3AsCH2C00-)的形式存在。
