土壤及灌溉水中Cd和Pb含量与蔬菜重金属富集的关联度分析
Correlation Analysis of Cd and Pb Content in Soil,Irrigation Water and Vegetables
摘要
Abstract
Soil,irrigation water and vegetables were taken randomly from Zhengzhou district vegetable fields,and the effects of soil and irrigation water on the content of cadmium (Cd) and lead (Pb) in vegetables were analyzed. The results showed that the Cd and Pb contents in the soil were significantly positively correlated with the contents in spinach,Chinese cabbage,pakchoi,lettuce and radish,while their correlations with those of Indian lettuce reached extremely significant level. The Cd and Pb contents of irrigation water were separately extremely significantly and significantly related with those of pakchoi, but were not significantly related with those of other kinds of vegetables except Indian lettuce. Meanwhile, the single factor pollution index and the comprehensive pollution index were adopted to investigate the Cd and Pb pollution in those vegetables. The results indicated that spinach and lettuce began to be polluted and the other four kinds of vegetables were clean.关键词
