To collect regional information on internal levels of pollutants in humans in Flanders, 1196 mother–child pairs were systematically recruited in 2002–2003 via 25 maternities across Flanders. Cd, Pb, PCB congeners 118, 170, 138, 153 and 180, p,p′-DDE — a key metabolite of DDT- and hexachlorobenzene (HCB) were measured in cord blood or plasma.
Parts of the population are permanently exposed to low levels of Hg° and Hg(II) from dental amalgam. It was the aim (1) to investigate the internal exposure to amalgam-related mercury from the kinetics of inorganic Hg in plasma and erythrocytes after amalgam removal, and (2) to estimate the amalgam-related absorbed dose.
Higher mercury concentrations were found in brain regions and blood of some patients with Alzheimer's disease (AD). Low levels of inorganic mercury were able to cause AD- typical nerve cell deteriorations in vitro and in animal experiments. Other metals like zinc, aluminum, copper, cadmium, manganese, iron, and chrome are not able to elicit all of these deteriorations in low levels,
Minamata Disease is a myriad of neurological and neurodevelopmental symptoms stemming from the pollution of Minamata Bay, Japan with 27 tons of organic mercury by the Chisso Corporation. The corporation denied responsibility and continued to pollute waterways for three decades. While research findings showing mercury was the cause of Minamata disease were concealed by the corporation,
Objective. This article estimates the financial impact of a ban on amalgam restorations for selected population groups: the entire population, children, and children and women of childbearing age. Methods. Using claim and enrollment data from Delta Dental of Michigan, Ohio, and Indiana and the American Dental Association Survey of Dental Services Rendered,
The etiology of most cases of Alzheimer’s disease (AD) is as yet unknown. Epidemiological studies suggest that environmental factors may be involved beside genetic risk factors. Some studies have shown higher mercury concentrations in brains of deceased and in blood of living patients with Alzheimer’s disease. Experimental studies have found that even smallest amounts of mercury
but no other metals in low concentrations were able to cause all nerve cell changes,
