重金属铊污染及防治对策分析

Analysis of Heavy Metal Thallium Pollution and Prevention and Control Measures

以重金属铊为研究对象,分析其污染来源及分布情况,经讨论后发现:铊元素受到迁移扩散作用影响而在矿物、水体、土壤、大气中均有存在,在不同环境状态下,铊含量及浓度存在差异,但最终经沉降与迁移后,铊元素主要集中在土壤与水体中,并随食物链影响动植物。基于此,对重金属铊污染进行防治过程中,应重点从土壤铊污染、水体铊污染两个角度进行防治治理。

This paper takes heavy metal thallium as the research object,analyzes its pollution sources and distribution,after discussion,it is found that thallium element is affected by migration and diffusion and exists in minerals,water,soil and atmosphere,in different environmental conditions,thallium content and concentration are different,but finally after sedimentation and migration,thallium element is mainly concentrated in soil and water body,and affects animals and plants with the food chain.Thallium pollution in water bodies is prevented and treated from two perspectives.
