This study aimed to evaluate possible health effects associated with long-term occupational exposure to low levels of mercury vapors. Forty-six subjects exposed to mercury and 65 healthy unexposed employees were studied. The subjects were administered a questionnaire on experienced symptoms and underwent clinical examinations as well as routine biochemical tests. Atmospheric and urinary concent...

Mercury (Hg) is one of the trace toxic and bioaccumulative global pollutants, due to its long atmospheric lifetime, it presents a significant challenge. The present study (1) utilizes total gaseous mercury (TGM) measurements made around former Hg-cell chlor-alkali plant (CAP) located in Pavlodar, Kazakhstan, predicts spatial distribution Hg over premises nearby city. It then (2) estimates envir...

Chlorinated organic compounds resu l t from ch lor inat ion treatment of wastewater. The discharges, containing these compounds, in to the aquatic environment have resulted in widespread concern. Invest igat ions have been conducted on the ef fects of these chloro-organics on aquatic l i f e . Most of the studies, however, have been conducted on zooplankton or higher organisms. Only l imi ted i...

The purpose of this study was to create a monoculture biofilm of a clinical isolate of Enterococcus faecalis and to determine susceptibility against four antimicrobial irrigants. Biofilms were subjected to 1-, 3-, and 5-minute exposures to one of the following irrigants: 6% sodium hypochlorite (NaOCl), 2% chlorhexidine gluconate (CHX) or one of two new products, <6% NaOCl with surface modifiers...

Mercury (Hg) is a global pollutant capable of bioaccumulates/biomagnifies along the trophic chain and posing concerns for organisms humans. The historical mining in Idrija (NW Slovenia) more recent activity chlor-alkali plant (CAP) sited Torviscosa (NE Italy) causes diffuse Hg contamination Marano Grado Lagoon (MGL, northern Adriatic Sea, Italy). Despite importance fishing aquaculture local inh...

Porous gas-diffusion electrodes (GDEs) are widely used in electrochemical applications where a gaseous reactant is converted to target product. Important for silver-based GDEs the chlor-alkali and CO2 electrolysis processes which silver catalyzes oxygen- or carbon dioxide reduction reaction. The wetting of porous utmost importance achieved performance electrode: completely dry electrode will re...
