摘要：

为了解电解铝厂氟污染对周边农作物的影响，通过采用氟离子选择电极法，对凯里某电解铝厂周边农作物的氟含量及污染程度进行研究。结果表明：铝厂周边农作物中氟含量最高为163.33 mg/kg，最低为16.73 mg/kg，平均含量为51.09 mg/kg，都已超过国家标准规定的农作物中氟污染物最大容许含量，农作物受到了较为严重的氟污染。不同农作物对氟的吸收、积累能力不同；农作物不同器官对氟的积累不同，对氟的吸收主要集中于叶片。铝厂周边不同区域的农作物都受到严重程度的氟污染，主要与铝厂的距离有关，距离铝厂越近，农作物受到氟污染越严重。

Abstract:

Understanding influence of fluoride from electrolytic aluminum factory on the crops. Fluorine contents in crops around an electrolytic aluminum factory in Kaili were monitored by a fluoride ion selective electrode method and its pollution level was analyzed. The results showed that the highest, the lowest and the average content of fluorine in crops was 163.33 mg/kg, 16.73 mg/kg, 51.09 mg/kg respectively. The fluorine pollution status in crops were all higher than the value of the national standard and the crops were polluted severely. The ability to absorb and enrich fluoride differed in different species. The enrichment of fluoride was different in different organ of crops and the leaf has stronger ability to absorb fluoride. There were severe fluorine pollution for all crops in different districts around electrolytic aluminum factory. The pollution level was clozely related to the distance between the sampling plots and the aluminum factory and the more severe fluorine pollution, the more near distance.
