摘要
采集锰矿开采加工区周边的南瓜、四季豆、豇豆、西红柿、白菜、苋菜、萝卜、莴笋、韭菜,并用湿消解法测定其锰、铁、锌、铜、铅、镉等重金属浓度。将测定结果与国家卫生标准和国家蔬菜营养成分进行对比,并利用单项污染指数法对其进行评价。研究结果表明,遵义锰矿开采加工区周边蔬菜受到重金属的污染程度依次为:锰>镉>锌>铁>铜>铅。其中苋菜、莴笋、白菜受锰污染最严重,其污染指数分别达到了29.663380、16.162590、15.898370;白菜、苋菜受到镉污染最为严重,其污染指数分别达到了12.252500和11.171000;蔬菜样品基本没有受到铅污染,有少部分蔬菜样品受到铜轻度污染。
The pumpkin, kidney bean, cowpea, tomato, cabbage, amaranth, carrots, lettuce and leek growing around manganese mining, area were collected to determine the concentrations of manganese, iron, zinc, copper, lead, cadmium and other heavy metals in them by the method of wet digestion respectively. The determination results were compared with those in the national health standards and national vegetables nutrients. At the same time, the evaluation was made with pollution index. The results showed that the pollution extent of vegetables around the manganese mining processingarea in Zunyi was： manganese 〉 cadmium 〉 zinc〉 railiron〉 copper〉 lead. Among them, the amaranth, lettuce, and cabbage suffer the most serious manganese pollution, and the pollution indexes reach 29.663380,16.162590 and 15.898370, respectively; The cabbage and amaranth suffer the most serious of cadmium pollution, and the pollution index reach 12.252500 and 11.171000, respectively. The vegetable samples do not suffer lead contamination. Few vegetables samples suffer mild copper pollution.
