The selenium isotopic ratios have been measured in the Yutangba Se deposit, Hubei Province, China. The results show that the δ 82/76SeNIST values vary from -12.77‰ to 4.93‰, which is the largest Se iso- topic varia...
The Yutangba Se deposit is a rare high-Se deposit in the world and it is well known for its high contents of Se, which reach 8590×10+{-6} . The ore-hosted rocks are dominated by cherts that have been well developed. ...

At the top of the Lower Permian Maokou Formation limestones are developed carbonaceous cherts (Plm3), which constitute the dominant seleniferous layer of the Yutangba Se deposit. The cherts contain as much Se as 1646...
Within the range of 0.01 km\+2 mini\|landscape in Yutangba, Enshi, Hubei Province, the content of Se in corn is very high. The average Se contents in root, stem, leaf and seed of corn were estimated to be 4.36±3.27mg...
SELENIUM is an indispensable trace element to human beings and normal animals but if found in excessively high dietary concentrations, it can cause poisoning. The most severe example of selenium poisoning occurred at ...
