UTTER

Mercury in the Atmosphere,issions to the atmosphere represent 45 to 87% of the total Hg emitted from precious metal mining and may account for a global input of 200–420 tons year.. These figures represent a contribution that can reach from 6 to 11% of the global anthropogenic atmospheric emission of mercury to the biosphere of 3550 tons year. (Nriagu 1990).

MUTED

Mercury in Biota,ms, in particular algae and lichens (Jordan et al. 1980) at the crown leaf level, and those mediated by the high diversity and biomass of ephiphytes typical of most tropical ecosystems (Benzing 1981; Nadkarni 1984).

保守

Mercury Contamination of Humans in Gold and Silver Mining Areas,a few studies had actually detected symptoms or clinical signs of Hg poisoning. Most health authorities agree that the lack of information on “mercurialism” among the exposed population is probably due to difficult logistics and the poor health conditions of the population which may mask symptoms of mercury poisoning.

桉树

Mercury in Tropical Aquatic and Terrestrial Systems,w last century USA gold rush sites, has been the subject of longterm studies concerning the fate of Hg in the environment. Unfortunately, however, even in these areas, few studies have dealt with geochemical and biogeochemical processes controlling Hg concentrations in water, sediments and soils.

Genetic aspects of mucopolysaccharidoses with special reference to heterozygous carrierse hereditary diseases. According to Lowry and Renwick (1971) they occur as seldom as 1:1,000,000 (MPS I), 1:150,000 (MPS II) and 1:300,000 (MPS IV). It is generally accepted that within a MPS-afflicted family only the same type of mucopolysaccharidosis occurs. This has been apparent ever since the f
