| In this study. mercury (Hg) and methylmercury (MMHg) concentrations in sediments from the northern parts of the Persian Gulf were assessed. Surface sediments were collected from nine stations in Hormozgan and Bushehr provinces. All analyses were performed on homogenized and lyophilized samples. Total mercury analysis was performed by thermal decomposition, amalgamation, Atomic Absorption Spectrometry (AMA 254) and methylmercury was analyzed by Headspace Gas Chromatography Atomic Fluorescence Spectrometry after aqueous phase ethylation of the extracted samples. Total mercury (THg) in sediments varied from 13 to 40 ng g-1dw and methylmercury accounted for 0.5% to 1.2% of total mercury. The organic carbon (OC) and organic matter (OM) content ranged from 0.5 to 1.4 and from 5 to 11%, respectively. |
