摘　　要：测定了京西煤矿煤矸石堆周边地区土壤及玉米、菠菜、韭菜等蔬菜中重金属Pb、Cr和Cd含量。结果表明,京西煤矿煤矸石堆周边地区土壤及玉米、菠菜、韭菜等蔬菜受到重金属污染,其中土壤的Pb含量较高,玉米中检测到Cr和Cd,但符合食品污染物限量标准;叶菜作物韭菜中含少量Pb和Cd,菠菜中测得一定量的Pb、Cr和Cd,均小于叶菜蔬菜污染物限量标准。针对京西煤矿煤矸石堆周边生态境污染状况,提出了重金属污染的防治对策。The contents of Pb,Cr and Cd in soil and vegetables such as corn,spinach and leek are measured in the surrounding area of coal gangue pile in Jingxi coal mine.The result showes that the soil and vegetables such as corn,spinach and leek are polluted by heavy metals in the surrounding area of coal gangue pile in Jingxi coal mine.The content of Pb in soil is high,and Cr and Cd are detected in corn,although they meet the food pollutant limit standard;there is a small amount of Pb and Cd in leek,and a certain amount of Pb,Cr and Cd in spinach,which are all lower than the leafy vegetables pollutant limit standard.In view of the ecological environment pollution around the coal gangue pile in Jingxi coal mine,the prevention and control countermeasures of heavy metal pollution are put forward.
