Background: Mercury in any form is poisonous and mercury toxicity most commonly affects the nervous, gastrointestinal (GI) and urinary systems. The aim of this study was to investigate the specific effect associated with mercury toxicity and to evaluate the effectiveness of iron and vitamin B6 supplement on mercury-induced toxicities in rats. Methods: This experiment was performed on 25 rats...

Background: Contagion of aquatic ecosystems to heavy metals especially mercury (Hg) has risen concerns about healthiness of marine organisms. Organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. In present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (ph...

Fast and reliable analytical methods for mercury speciation would aid in understanding mercury offgas chemistry. Presently, the U.S. Environmental Protection Agency (EPA) regulates only total mercury; however, many studies indicate that mercury toxicity is highly dependent on the mercury speciation. For example, amalgams and mercury sulfides have relatively low toxicities, while organomercury a...

Juvenile rainbow trout (Salmo gairdneri) were exposed to 100 ppb mercury (as HgCl2) in the water for 14 days. Concentrations of mercury in water and fish organs were monitored using radiolabeled mercury. Tissues from kidney and liver were fixed, and sections were developed by autometallography, a method whereby accumulations of mercury sulfides and/or mercury selenides are silver amplified. In ...

the petrochemical industry is the most important and most widely active industries in the country. due to the variety and complexity of industrial products, it also produces a wild range of pollutants. mercury waste disposal from chlor-alkali units is one of the fundamental problems of this industry. various studies have shown that phytoremediation system for removal of mercury from aqueous sol...

abstract background and objective: there have been concerns over possible association between mercury and neurodevelopmental outcomes in infants. in this study we aimed to determine whether blood levels of mercury are above safe values in iranian infants or not. materials and methods:  a total of 85 infants (0, 2, 4 and 6 months old) were enrolled in this study. all of them received vaccines ac...
