Biomonitoring of PAH pollution in high-altitude mountain lakes through the analysis of fish bile
Article Abstract:
Pollution of high-mountain lakes by polycyclic aromatic hydrocarbon (PAH) were studied to determine the effectiveness of HPLC flurorescence and gas chromatograpy-mass spectrometry. Five lakes were chosen from throughout Europe. Because of the remoteness, and cold temperature of these lakes fish grow much slower than fish in low-altitude lakes. This situation concentrates pollutants in these fish. The result showed that lakes east of heavily industrialized locations were the most contaminated. The research also showed that both analytical methods produced similar results.

Comparison of digestion media for speciation of mercury in the seagrass Zostera marina L. Followed by quantification by hydride generation - atomic fluorescence spectrometry
Article Abstract:
Seagrasses are important to the cycling of mercury in marine environments. A quick method to analyze mercury speciation in the eelgrass Zostera marina L. makes use of alkaline tetrabutylammonium bromide, which is a hydrophobic digestion reagent. It was determined that MeHg+ represented 6.5% of the total mercury concentration.
