Analyses of the certified reference material CRM 463 showed recoveries of 96% (3.17% VC) and 92% (2.53% VC) for THg and MeHg, respectively. Results are in consonance with those of the certified values, showing the proposed method for MeHg extraction as an adequate procedure for measuring this form of Hg in the muscle of the seawater fish.The whole process is quite straight forward,with excellent recoveries while the analyses for THg and MeHg can be made in the same analytical system.
THg and MeHg concentrations in the muscle tissue of sardine, anchovy and tuna are shown in Table 2. The highest THg concentrations were observed in the following order: tuna fish, anchovy and sardine. Our data reported herein are comparable to THg concentrations in species purchased in Catalonia, Spain (Mart?-Cid et al. 2007), and in European pilchard (S. pilchardus) from Tunisia and other Med
