Abstract

P(論文)自然環境中の重金属による汚染は人体にとっては特に重大である.人体の重金属汚染指標としては毛髪中の重金属値が用いられている.本研究では岡山県民の毛髪中水銀量を知るために湯原, 湯郷, 奥津, 備前原地域において採取した毛髪について還元気化原子吸光分析法により分析した.その結果, 湯原地域4.57±1.81μg/g, 湯郷地域4.21±1.26μg/g, 奥津地域5.98±2.05μg/g, 備前原地域3.36±1.35μg/g, 全体では4.33±1.58μg/gとなり正常値の範囲内であった.また試料提供者のうち3.5~4.0μg/gを示す者が最も多かった.湯原, 湯郷, 奥津地域の試料提供者は温泉利用者がほとんどであったが, 温泉中に含有される総水銀量と毛髪中総水銀量との関係は認められなかった.Heavy metal contamination under environment in nature is very serious for human body. Heavy metal value in human hairs has been having a reliable source for an index of the above-mentioned contamination. Those hairs collected as investigating object in the area of Yubara, Yunogo, Okutsu and Bizen Hara were analyzed by method of the Flameless Atomic Absorption Spectrophotometry. And as the result, its value indicated 4.57±1.81 in Yubara, 4.21±1.26 in Yunogo, 5.98±2.05 in Okutsu, and 3.36±1.35 μg/g in Bizen Hara. And all total value indicated 4.33±1.58 μg/g in those area as a whole. But those indications showed within the limitation of normal value. Also most of those values indicated 3.5~4.0 μg/g. Those suppliers in the area of Yubara, Yunogo, and Okutsu were customers for using Hot Spring. But the relation between Mercury content in Hot Spring and Mercury content in the human hairs at all total amount was not recognized.departmental bulletin pape
