摘要
铊作为剧毒的重金属元素,具有较强的蓄积性、潜伏性和迁移性,含铊矿床的开采及其工业三废的大量排放,都可导致铊进入地表环境,参与到土壤圈、水圈、大气圈、生物圈物质循环,并逐步在土壤和水体中富集,破坏生态环境,最终会通过食物链危及人体健康。通过对云南省武定县土地质量地球化学调查,表明了农业活动对铊污染扩散有一定影响,建议将铊元素纳入农业用地土壤环境质量标准及污染物排放行业标准,扩大监管范围,为安全开发利用铊资源提高防治能力。
As a severe poison heavy metal element Tl, The accumulation, latency and migration of Tl is very intense.The mining of Tl-bearing deposit and the release of a lot of industry 3-waste of it could result Tl into the surface environment, material circling of soil, water and air atmosphere, and progressive concentration in soil and waters, damage to the ecological environment, finally harm to the health of people by food chain.According to the geochemical survey of land quality in Wuding, Yunnan, showing the agriculture production has a certain influence on the expansion of Tl pollution.We suggest that Tl may be put into the quality standard of agriculture field soil environment and profession standard of pollution waste release, expansion of the supervision range, improvement of the prevention ability in the safe development and use of the Tl resources.
