Poisoning, mercury

Health Hazards Information - Recommended Personal Protective Equipment Rubber gloves, dust mask, goggles Symptoms Following Exposure The general symptoms are those of mercury poisoning, developing rapidly after ingestion but more slowly after low repeated exposures. Contact with eyes... 

EDTA also is used to treat lead and mercury poisoning, as it can lock up those metals so they can do no harm in the body.

The first is the story of the high school physics teacher who came down with a strange illness eventually diagnosed as mercury poisoning. The cause Over the years, minute amounts of this metal had been spilled in the poorly ventilated lecture room. The students suffered no ill effects since they spent so little time there. Fortunately, the teacher recovered, the room was completely refurbished, and strict rules were introduced concerning the handling of mercury. 

An elegant complementary test to mercury poison is the use of dienes as selective poisons for homogeneous catalysts, due to their strong coordination to metal centres yielding inert catalytic complexes. In addition, their interaction with metal surfaces is weak. If the presence of diene (dienemetal =1 1) inhibits the catalytic process and Hg test does not, homogeneity can be strongly supported.

This area was the most profusely studied in the AQUATERRA project in terms of biological effects in fish populations. Barbel and bleak were the sentinel species selected in this area and an array of histological and biochemical tests were used to monitor the impact due to three major sources of pollution mercury and OCs at Monzon (with a comparison in one of the papers with Flix) and PBDEs in Barbastro [1—4, 37]. Mercury pollution was directly correlated to an increase of MTprotein in the liver of barbel captured downstream Monzon when compared to samples captured upstream (Fig. 3a). However, mRNA quantitative analyses failed to show any differences between downstream and upstream Monzon, neither correlated with MT protein levels. Further studies showed that MT mRNA in liver is a rather weak marker for chronic metal pollution in liver (see below) [4], The presence of degenerative hepatocytes in barbels and bleaks was also linked to mercury poisoning although it can also reflect the impact by other pollutants, like OCs or PBDEs (Fig. 3e). 

Signs of mercury poisoning in birds includes muscular incoordination, falling, slowness, fluffed feathers, calmness, withdrawal, hyporeactivity, hypoactivity, and eyelid drooping. In acute oral exposures, signs appeared as early as 20 min postadministration in mallards and 2.5 h in pheasants. Deaths occurred between 4 and 48 h in mallards and 2 and 6 days in pheasants remission took up to 7 days (Hudson et al. 1984). In studies with cotumix (Coturnix coturnix coturnix), Hill (1981)... 

Methylmercury affects the central nervous system in humans — especially the sensory, visual, and auditory areas concerned with coordination. The most severe effects lead to widespread brain damage, resulting in mental derangement, coma, and death (Clarkson and Marsh 1982 USPHS 1994). In mule deer (Odocoileus hemionus hemionus), after acute oral mercury poisoning was...
