Human exposure to mercury intoxication through contaminated fish ingestion has been well studied, mainly among Japanese population. The Brazilian population, particularly in the Amazon region, is now in focus due to findings of fish contamination. Major health impacts caused by mercury affect mostly people who have a regular fish diet. A continuous checking for mercury content in the most consu...

We assessed mercury levels in the feathers of little tern (Sternula albifrons) chicks from hatching to fledging and in their prey captured by adults in three main foraging habitats: lagoon, salinas, and adjacent sea. These data were used to model mercury concentration in chick feathers through food ingestion, in order to explore the effects that changes in diet would have on the mercury burden ...

heavy metals, in particular mercury, are important for the public health due to their toxicity and endurance in the environment. in the present study, the distribution of mercury was surveyed along the coast of the caspian sea (mazandaran province). twelve stations were selected and from each station 5 samples were randomly collected followed by chemical analyses. an inverse weight-distance met...

Mercury is considered one of the most toxic elements for plants and animals. Nevertheless, in the Middle East, Asia and Latin America, whitening creams containing mercury are being manufactured and purchased, despite their obvious health risks. Due to the mass distribution of these products, this can be considered a global public health issue. In Mexico, these products are widely available in p...

CONTEXT Fish consumption has been associated with a decreased risk of coronary artery disease. Recent studies have illustrated that the high mercury content in cold-water fish may negate the cardiovascular benefits of fish meals. Fish oils have similar antiatherogenic properties to fish, and similar studies should be performed to determine the level of mercury in fish oils. OBJECTIVE To deter...

Repeated doses of sodium selenite (Se) were administered to rats receiving repeated (IV or PO) doses of 0.25 or 2.5 mg Hg/kg methylmercuric chloride (Me2(203)Hg). Se (0.5 mg/kg) was observed to alter the distribution of Me203Hg among tissues as well as among subcellular fractions of kidneys and liver. An excess of selenium resulted in a twofold decrease in the mercury content of kidneys and a s...

Mercury is a potent toxicant of concern to both the general public and occupationally exposed workers (e.g., dentists). Recent studies suggest that several genes mediating the toxicokinetics of mercury are polymorphic in humans and may influence inter-individual variability in mercury accumulation. This work hypothesizes that polymorphisms in key glutathione synthesizing enzyme, glutathione S-t...

The aim of the experiment was to evaluate mercury content in the hair of people in Lubartów and surrounding areas (Lublin region, Poland) depending on their place of residence, lifestyle and diet. mean mercury content in the hair of tested general population from Lubartów and surroundings, which amounted to 0.10±0.07 μg g-1, was similar to the results achieved by other authors for populations f...

Samples of fresh and fixed tissues from infants with exomphalos treated by thiomersal application were analysed for mercury content. The results showed that thiomersal can induce blood and organ levels of organic mercury which are well in excess of the minimum toxic level in adults and fetuses. The analysis of fresh and fixed tissues must be carefully controlled against normal tissues in order ...
