赣州钨矿区及工业区蔬菜重金属含量及污染评价

Assessment of Heavy Metals Pollution and Content on Vegetables in Ganzhou Tungsten Ore and Industrial Areas

通过A区为王母渡钨矿主矿区龙潭村,B区为赣州香港工业园,C区为赣州有色工业园,D区为赣州王母渡钨矿东埠头坑口上邦村,E区为赣县大田老稀土矿矿区的蔬菜作为研究对象,对蔬菜进行污染程度评价.结果表明,在A区龙潭村内,叶菜类中的紫叶菜中铅(Pb)含量超标,超标29.3%;紫叶菜的综合污染指数高于0.7,超过警戒限,属于尚清洁等级.B区赣州香港工业园区内,豇豆受到的污染程度最严重,超标292%,空心菜中的铅(Pb)含量超标为75%,茄子中的铅(Pb)超标161%;C区赣州有色工业园区内,豇豆中的铅(Pb)超标,超标288%;D区和E区赣州王母渡钨矿东埠头坑口上邦村内,蔬菜样品中的重金属含量均符合国家限量标准.

In this article, pollution evaluations on vegetables are studied on the following five areas： area A- Longtan Village of the main mine area in Wangmudu Tungsten Ore, area B- the Hong Kong Industrial Park inGanzhou, area C-Ganzhou Nonferrous Industrial Park, area D- Shangbang village in the east quay of Wangmudu Tungsten Ore, and area E-an old rare earth ore in Gan Country. The results show that： in area A,the content of the lead （Pb） in purple leaf exceeds 29.3 %; and the integrated pollution index of purple leaf is 0.7% higher than the standard but still belonging to moderately clean level. In the area B, cowpeas arepolluted most seriously with lead content exceeding 292 %; the content of lead （Pb） in water spinach exceeding 75 % and in eggplant 161%. In area C, the content of lead （Pb） in cowpeas exceed 288 %; In the areas of Dand E, the heavy metal content of vegetable samples fits the national limits.
