摘要
随着石棉对人类健康的巨大危害逐渐被揭露,石棉制品的禁用已成为国际趋势。从土壤中石棉的检测技术、石棉健康风险临界值研究、石棉土壤发育特征、理化生特性及石棉土壤治理几个方面对石棉土壤研究进展进行综述,并对今后的研究方向做出展望。文献分析结果发现,土壤中石棉的检测技术还很不成熟,健康风险临界值还缺乏科学依据,石棉母质上发育的土壤肥力差,镍等重金属含量较高,治理较为困难,今后应加强不同气候带土壤发育演变、石棉矿物与植物根系相互关系、重金属生物地球化学特征及石棉土壤改良等方面的研究。
With the reveal of the hazard of asbestos to human beings, prohibition of asbestos has been the international trend. In this paper, the test method of asbestos in soil, critical value of asbestos to human health, pedogenesis, physical, chemical and biological feature of asbestos- containing soil, and treatment of asbestos- containing soil were discussed. Then some directions of research of asbestos- containing soil were provided. The results showed that the test method of asbestos in soil isn＇t perfect; the critical value is subjective; the soils developed from asbestos were unfertile; the heavy metal contents were high, asbestos soil is difficult to harness. In the future, the pedogenesis, interaction between asbestos and root, and biogeochemical feature of asbestos soil in different climate zone must be studied.
