mercury is a dangerous and an extremely toxic element, which can transfer to the food chain.presence of this element in the atmosphere particularly during the rainy seasons cause soil and environmental pollution, therefore this research will evaluate the transformation of mercury vapor from the atmosphere through precipitation into the soil. in the present study, mercury concentrations were det...

This study determined the extent of heavy metal contamination local fruit in Rayong, Thailand, an area where industrial base is adjacent to agricultural areas. Dietary exposure products grown contaminated areas can cause multiple adverse effects human body. In order avoid such undesirable effects, concentrations metals [arsenic (As), cadmium (Cd), copper (Cu), mercury (Hg), lead (Pb), and zinc ...

Transmission of light through an atomic sample placed between crossed polarizers in a magnetic field is jointly determined by Faraday rotation and net absorption: transmission increases with rotation and decreases with absorption. Both rotation and absorption are proportional to the atomic density N0, hence, in a certain range of N0, the two effects may compete yielding a distinct density depen...

this study focus on the preparation of two supports including activated carbon derived from medlar and palladium nanoparticles loaded on activated carbon (pd-np-ac). subsequently, both adsorbent modified with a novel schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. the method is based on c...

We use the coherent backscattering interference effect to investigate experimentally and theoretically how coherent transport of light inside a cold atomic vapor is affected by the residual motion of atomic scatterers. As the temperature of the atomic cloud increases, the interference contrast decreases dramatically. This emphasizes the role of motion-induced decoherence for resonant scatterers...

Selected cultures of mercury-resistant bacteria degrade the fungicide-slimicide phenylmercuric acetate. By means of a closed system incorporating a flameless atomic absorption spectrophotometer and a vapor phase chromatograph, it was demonstrated that elemental mercury vapor and benzene were products of phenylmercuric acetate degradation.

OBJECTIVES The study aimed at assessing the effect of low-level exposure to mercury (Hg) vapor from amalgam fillings among dental surgery staff in the city of Łódź, Poland. MATERIALS AND METHODS The study group was composed of 51 workers (mean age, 39.25+/-11.05 years) employed in dental surgeries; the control group comprised 16 white-collar workers (mean age, 40.05+/-10.57 years) of the Nofe...
