BACKGROUND Observational studies in epidemiology always involve concerns regarding validity, especially measurement error, confounding, missing data, and other problems that may affect the study outcomes. Widely used standard statistical techniques, such as multiple regression analysis, may to some extent adjust for these shortcomings. However, structural equations may incorporate most of these...
Human hair and blood samples from persons living in the town of Wanshan, a mercury mine area in Guizhou Province of China, were collected and the quantitative speciation and structural information of Hg and S in hair samples and of Hg in erythrocyte and serum samples were studied using X-ray absorption spectroscopy. Least-squares fitting of the X-ray absorption near-edge spectra found that inor...
Introduction: Mercury is a highly toxic and persistent contaminant found in food parts of the environment. Over years, global research on mercury poison has soared owing to concerns about its effects human health, occupational safety, environmental sustainability. Although numerous studies have identified examined various types, sources, toxicity, exposure, impacts mercury, comprehensive landsc...
Minamata Disease was discovered for the first time in the world at Minamata City, Kumamoto Prefecture, Japan, in 1956 (Minamata Disease Research Group; 1968, Harada M; 1995), and for the next time at Niigata City, Niigata Prefecture, Japan, in 1965 (Tsubaki T & Irukayama K; 1977). The both cases were attributed to the methyl mercury that was generated in the process for producing acetaldehyde u...

EXECUTIVE SUMMARY This study of mercury contamination in Newark Bay sediments was initiated from a broader study of mercury sources and material balance in the New York-New Jersey Harbor, conducted for the New York Academy of Sciences' Harbor Consortium by Themelis and Gregory (2001). The author of this report concluded that a more in-depth study should be conducted on a smaller area within the...
