| 摘 要： | 恩施高硒区的硒来源于煤.煤中除硒外,尚有高含量的氟.此外,本地尚分布有丰富的硫铁矿,居民用作生产硫磺.由于环境污染严重,因此在观察硒的毒性时,应考虑其它有关元素的含量.本文测定了居民发中的Cd,Hg,As以及全血中的Cd,Zn和Cu等元素.从组织和血中这些元素的含量来考虑,唯有Cd对硒中毒的影响值得注意.

| Abstract: | The source of Se in seleniferous area in Enshi is mainly coal mine. In addition to Se, F and Te content is also high in the coal distributed in this seleniferous area.Pyrite is also abundant and was used for the production of S by the local residents.Because of the heavy environmental pollution, it is important to estimate the possible presence of other elements which may influence the toxicity of Se.Content of Cd, Hg and As in hair and Cd,Zn and Cu in whole blood were thus determined.According to the concentration of the elements presented in tissue and blood, it may be that only the possible influence of Cd on Se toxicity is worthy of consideration. |
