Thallium is a rare and easily dispersed element with high toxicity to organisms. Relatively high levels of thallium (approximately 9.58 mg kg(-1)) had been found in aqua regia soil extract of an accidentally polluted soil from south of Spain. To assess the available and leachable portions of thallium in the polluted soil, single and sequential extraction procedures have been utilized. Further, X-ray diffraction and scanning electron microscopic studies have also been used to find out the mineral phases. The amount of thallium extracted by the extracting agents in comparison to aqua regia, as well as the different phase associations are discussed.
铊是一种稀有且易于扩散的元素，对生物体具有高毒性。在西班牙南部一块意外污染土壤的王水土壤提取物中发现了相对较高含量的铊（约9.58毫克/千克）。为了评估污染土壤中铊的可利用和可浸出部分，采用了单次和连续提取程序。此外，还利用X射线衍射和扫描电子显微镜研究来确定矿物相。讨论了与王水相比，提取剂提取的铊量以及不同的相缔合情况。
