Abstract
The concentrations of methylmercury (MeHg) and ethylmercury (EtHg) were determined in fish and shellfish. Both MeHg and EtHg were isolated by acid leaching (KBr-H2SO4-CuSO4); MeHg and EtHg bromides were extracted into an organic solvent [cyclohexane/ethyl acetate (1 : 1)], then reextracted into 1% cysteine-sodium acetate. MeHg and EtHg bromides were derivatized with sodium tetraphenylborate (NaBPh4), and extracted with hexane. The organic phase containing methylphenylmercury and ethylphenylmercury was injected into GC/MS (SIM). As a result, even if we did not use benzene or toluene for the extracting solvent, it became possible to extract MeHg and EtHg well. The performance evaluation results, trueness (%), repeatability (RSD%) and reproducibility within the laboratory (RSD%), were MeHg 106.4, 8.9, 12.1 and EtHg 87.4, 8.3, 7.6, respectively. It was shown that the method satisfies the performance criteria set by Ministry of Health, Labor and Welfare.
