Seven parameters of renal dysfunction (urinary excretion of albumin, orosomucoid, beta 2-microglobulin, N-acetyl-beta-glucosaminidase (NAG), and copper; serum creatinine concentration, and relative clearance of beta 2-microglobulin) were examined in a group of chloralkali workers exposed to mercury vapour (n = 89) and in an unexposed control group (n = 75). Serum concentrations of immunoglobuli...

In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function ...

Mercury Levels Lower in Great Lakes, but Still High Although mercury concentrations have decreased about 20% in fish, fish-eating birds, and inland lake sediments across the Great Lakes region in recent decades, levels in top predator fish and wildlife are still dangerously high, and in some places concentrations in some fish and wildlife may now be increasing, according to a new report. Levels...
