Poisoning by Methyl Mercury Compounds

Poisoning by methyl mercury compounds.

In 1940 Hunter and others, reporting on cases of poisoning by methyl mercury compounds, showed that those working with certain organic mercury derivatives are exposed to great danger. In 1945 Herner collated the cases of poisoning by alkyl mercury compounds recorded in' the literature. The seven cases hitherto published show a characteristic clinical picture beginning with a sensation of numbne...

[Mercury poisoning].

Certain heavy metals such as mercury, lead, arsenic and cadmium are toxic even in reduced concentrations in blood. Their accumulation in the body causes serious illnesses. The most important heavy metals in human pathology are: mercury (Hg), cadmium (Cd), arsenic (As) and lead (Pb). The author mentions the heavy metal sources of poisoning, their toxicokinetics and toxicodynamics, clinical featu...

Poisoning by ethyl mercury toluene sulphonanilide.

Poisoning by a fungicide used for seed-borne diseases of cereals, ethyl mercury p-toluene sulphonanilide (Granoson M, Dupont), is described. It affected a large number of farmers and their families who used the dressed seed in the preparation of home-made bread. Many systems were involved, including the kidneys, the gastro-intestinal tract, the skin, the heart, and the muscles, but involvement ...

biotransformation of mercury compounds by environmental microorganisms

forty bacteria species commonly found in soil, sediments, and sewage effluent were exposed for acclimation to inorganic and organic mercury compounds using sterilized sediments as the culture medium. screening tests for the ability of microorganisms to methylate inorganic mercury were made on all 40 species after acclimation to 13.5 mg/i mercuric chloride. additional screening tests for demethy...
