The effect of heavy metals on differentiated neuronal and glial cells
… cellular models, the toxicity of zinc, lead, mercury, methylmercury and thimerosal were investigated using assays of cell viability and morphology on differentiating N2a and C6 cells. Initial research revealed thimerosal, methylmercury and cadmium to be the most toxic compounds tested, in …

Detection of vapor phase mercury species by laser fluorescence methods
Elemental and compound mercury are often both volatile and air stable. Several mercury species emissions have been identified in off-gases from industrial processes. The high toxicity of mercury species and the presence of mercury species in municipal waste and coal have prompted a demand for a …

The determination of mercury and its organo compounds by high performance liquid chromatography-atomic flourescence spectrometry.
… sediments samples for the determination of total mercury by cold vapour atomic fluorescence spectrometry were investigated. Satisfactory results were obtained from a closed microwave digestion procedure for which 0.5g of soil or sediment sample was taken and heated with 3 mL of nitric acid and 1 …

UNCERTAINTY CONTRIBUTIONS TO SPECIES SPECIFIC ISOTOPE DILUTION ANALYSIS
Mercury speciation in solid sample matrices has been investigated using high performance liquid chromatography (HPLC) coupled with multicollector sector field (MCSF) and quadrupole (Q) inductively coupled plasma mass spectrometry (ICP-MS) for species specific isotope dilution mass spectrometry …

Investigation of constructed wetlands capability to remove mercury from contaminated waters
… (c) acidic; and (d) agricultural wastewater. Mercury has been used intensively by wide variety of industries because of its unique properties. Consequently, it was present at various levels in wastewater discharged. The ability of constructed wetlands to serve as a sink of mercury before …

Alterations in lymphocyte signalling produced by exposure to mercury
… the highly lipid-soluble organomercurial compounds CH3HgCl and TMS were expected to reduce responses to polarized stimuli only in conjunction with – and not prior to – loss of microtubule integrity and the onset of necrotic cell death. Two general patterns of effects were observed. In …
