A simple method for methylmercury (MeHg+) determination in human venous blood is described using GCICP- MS. The blood sample preparation consists in the extraction with a mixture of 6M HCl and NaCl, pH adjustment, derivatization of mercury species using NaBPh4 with simultaneous extraction of products into hexane. The detection limits for MeHg+ were 86 ppt (as Hg) in the optimized method. The sample volume for repeated measurements was 150 l. The total Hg level in blood was determined by AAS using the amalgamation technique.
