土壤—植物系统铅污染现状与修复技术的研究

Lead Pollution in Soil-plant System and Its Restoration

土壤受到铅污染后会导致农作物生长受阻,产量降低、品质下降.并且通过食物链影响人体多个系统和器官,特别是对儿童神经系统的危害性更大.植物对土壤铅的吸收主要和土壤的理化性质有关.铅污染土壤的修复方法很多,但各有利弊,在选择修复方法时,要结合多方面因素综合考虑,因地制宜,综合应用,选择最经济、有效的修复方法或其组合.

The pollution of soil will hinder the growth of crops,lead to the reduction in yield and decline in quality. What＇s more, it will,via the food chain,affect human being＇s organic system,especially children＇s nervous system. The plant＇s absorption of lead relates to the ,physical-chemical nature of the soil, There are various ways to restore the lead-polluted soil, but all have pros and cons. Therefore ,we should take every element into consideration ,choosing the optimum one or a combination.
