摘要
世界各国土壤均出现不同程度的重金属污染问题。土壤铅超标不仅影响植物体的正常生长,而且通过食物链危害人类健康。分析我国土壤铅污染的现状,介绍当前常用的治理措施,探讨利用4A沸石钝化技术固定土壤铅、降低其生物有效性、达到修复重金属铅污染土壤目的的必要性与可能性。
Soil heavy metal pollution is a universal problem in the world.Soil lead exceeding the allowed standard not only affects the plant＇s normal growth,but also harms the human health through the food chain.This article analyzes the present soil lead pollution in China,presents the currently commonly used treatment measures,and discusses the necessity and feasibility to reduce the bioavailability to achieve the goal of repairing the heavy metal lead contaminated soil using the 4A zeolite deactivation technology to fix soil lead.
