Outline of Final Research Achievements

Health hazards caused by arsenic pollution of tube-well water are endemic in Asian countries. We have collected the samples of hair, nail, blood, urine, and drinking water from Bangladesh and Cambodian residents to assess the dose-response relationship between the levels of arsenic exposure and health effects. In Bangladesh, we found that elevating levels of arsenic exposure were well correlated with biochemical indicators for hepatotoxicity, atherosclerosis, and hypertension. In Cambodia, the contribution of tube-well water as well as the consumption of fish and rice to arsenic exposure was investigated. Chemical forms of arsenic in freshwater fish in Cambodia were precisely evaluated. In a cell culture system, we found that alternative splicing of the gene for arsenic methylation (detoxifying) enzyme could be a cause for individual difference in sensitivity to arsenic toxicity. Also, we found that arsenic exposure reduces the ability of natural killer cells for killing tumor cells.
