| Outline of Final Research Achievements |
We have reported an analytical methods for arsenic compounds in seafood , among foodstuffs. In addition, we have focused on our attention to dimethylmonothioarsinic acid (DMMTA), which is known as an intermediate metabolite of arsenic compounds in seafood and an high toxic metabolite. Concerning cytotoxicity and toxic mechanism of DMMTA, we found that the toxicity of DMMTA deeply involved GSH and that clarified the possibility that multiple metabolites produced by GSH are involved in the mechanism. The results seem to be very useful for risk assessment of arsenic compounds derived from seafood.
