Plasma Compartment

This study aims to evaluate the effects of polymorphisms in glutathione (GSH-) related genes (GSTM1,GSTT1,GSTP1,GCLM, andGCLC) in the distribution of Hg in the blood compartments in humans exposed to methylmercury (MeHg). Subjects (n=88), exposed to MeHg from fish consumption, were enrolled in the study. Hg species in the plasma compartment were determined by LC-ICP-MS, whereas genotyping was performed by PCR assays. Mean total Hg levels in plasma (THgP) and whole blood (THgB) were10±4.2and37±21, whereas mean evels of plasmatic MeHg (MeHgP), inorganic Hg (IHgP), and HgP/HgB were4.3±2.9,5.8±2.3 µg/L, and0.33±0.15, respectively.GSTM1andGCLCpolymorphisms influence THgP and MeHgP (multivariate analyses,P<0.050). Null homozygotes forGSTM1showed higher THgP and MeHgP levels compared to subjects withGSTM1(THgPβ=0.22,P=0.035; MeHgPβ=0.30,P=0.050) and persons carrying at least one T allele forGCLChad significant higher MeHgP (β=0.59,P=0.046). Also, polymorphicGCLMsubjects had lower THgP/THgB than those with the nonvariant genotype. Taken together, data of this study suggest that GSH-related polymorphisms may change the metabolism of MeHg by modifying the distribution of mercury species iin plasma compartment and the HgP/HgB partitioning.

The objective of this study is to determine the Pb concentration and 206Pb/204Pb, 206Pb/207Pb, 206Pb/208Pb from several Romanian winemaking regions, in order to highlight credible geographical markers of wine origin. The Pb level concentration and the ratios of 206Pb/204Pb, 206Pb/207Pb, 206Pb/208Pb were determined in 25 white and 9 red wines using ICP-MS techniques. Based on 206Pb/207Pb isotope ratios it can be concluded that the vines grown in the Tîrnave vineyard [Blaj (1.1790 average value)], Huși vineyard [Huși (1.1958 average value wine center), Averești (1.1908 average value)] and Iași vineyard [Copou (1.1875 average value) wine center], show traces of atmospheric pollution with lead [if 206Pb/207Pb=~1.1700-1.2200 (atmospheric pollution)]. Combining the 206Pb/204Pb with 206Pb/208Pb isotopic ratio may carry out a separation on the vineyards and wine-growing centers. Based on 206Pb/204Pb, 206Pb/207Pb and 208Pb/206Pb a separation of the wine samples was possible.
