杭州市菜地蔬菜对土壤重金属的富集特性研究
Heavy Metals Accumulation Characteristics of Vegetables in Hangzhou City, China
摘要
Abstract
A field survey of heavy metal concentrations in soils and vegetables grown in 30 vegetable farmlands of Hangzhou City were car-ried out. Through calculating the bioconcentration factor(BCF)and transfer factor(TF)for different heavy metals(Cu, Zn, Cd, Cr and Pb)in 27 kinds of different vegetables which belong to leafy vegetables, root vegetables or eggplant fruit vegetables, assessing their accumulation characteristics of heavy metals according to the differences of the bio-concentration factor, the reasonable proposals were put forward to opti-mize the planting structure of vegetables in mild and middle-level heavy metal contamination soils. The experimental results were as follows:In soils with mild and middle-level heavy metal contamination, leafy vegetables, such as crown daisy, cabbage, celery and Chinese long cab-bage, had relatively low enrichment ability of heavy metals, so as the root and fruit vegetables like white radish, carrot, tomatoes, hence these vegetables could be planted preferentially. In contrast, some kinds of vegetables, including white amaranth, red amaranth, tatsoi, broccoli, gy-nura, brassica juncea and lettuce of leafy vegetables, lactuca sativa, taro, red radish and cherry radish of rhizome vegetables and sweet pepper of fruit vegetables, had relatively high accumulation ability of heavy metal, which should be avoided to be planted in soils with mild and mid-dle-level heavy metal contamination.关键词
