摘　　要：用原子吸收分光光度计石墨炉法分析了西江边、国道边、铁钉厂和陶瓷厂附近土壤的铅、镉含量,同时研究这些土壤上生长的少花龙葵、甘薯嫩叶、苦麦菜、香芹和西芹5种蔬菜的铅、镉含量。结果表明,蔬菜中铅镉含量与土壤受到的污染程度呈正相关,不同种类的蔬菜对铅、镉富集程度不同。The paper studies the lead and cadmium contents in four kinds of soil and the both heavy metals in five kinds of vegetables there by graphite furnace- atomic absorption spectrophotometer. The result shows that there is positive correlation between the content of lead and cadmium in vegetables and the pollution degree of soil, and that the degree of heavy metal enrichment varies with different vegetables.
