| 摘 要： | 本文综述了铊在岩矿石、土壤、植物、动物及大气等环境介质中的分布和运移机理及一些生物效应。在矿床中 ,铊主要分布在低温热液铊、铅、锌、锑、汞、砷等矿床中 ,铊的富集与其亲硫性及有机质密切相关 ,TlCl4 ]-是铊迁移的主要形式。在土壤中 ,铊主要以水溶态、硫化物结合态、硅酸盐结合态和有机质结合态存在 ,水溶态的铊容易迁移。在植物中 ,铊的运移与钾在植物中的传输有关。在动物中 ,铊对各组织器官的亲和能力依次为 :肾 >睾丸 >脾 >前列腺 >毛发。在大气中 ,铊主要以TlF形式迁移

| Abstract: | This paper deals with the dispersion, migration and some biological effects of thallium in rocks, ores,soils, plants, animals and atmosphere. In ores, thallium is dispersed mainly in the low\|temperature ore deposits of Tl, Pb, Zn, Sb, Hg, and As. Enrichment of thallium is closely related with the affinity of thallium to sulfide and organic matter. \\+- is the main form of migration of thallium. In soils, thallium is present in the form of water\|dissolved and sulfide\|, silicate\| and organic matter\|bound species. Water\|dissolved thallium is easy to migrate. In plants, the migration of thallium is closely related with the migration of K. In animals the affinity of Tl isotopes in tissue organs follows the order: kidney >testicle >liver >spleen >prostate >hair. In atmosphere, thallium migrates mainly in the form of TlF. |
