摘要：
The study analyzed metals (Zn, Cu, Cr, As) content in vegetables of vegetable bases of Lanzhou City. Metals content in Solanum tuberosum, Solanum lycopersicum, Solanum melongena, Capsicum annuum, Vigna sinensis, Brassica oleracea, and Allium fistulosum of vegetable bases of Lanzhou City showed significant difference. Overall, the highest content of Zn was found in Allium fistulosum, and the lowest was in Solanum lycopersicum; the highest content of Cu was found in Solanum tuberosum, while lowest in Solanum lycopersicum; the content of Cr was highest in Allium fistulosum, and lowest in Brassica oleracea; for As, the highest content was found in Allium fistulosum, and the lowest was in Brassica oleracea. The content of metals (Pb, Zn, Cu, Cr and As) accumulated in vegetables have strong correlation with metals content in the soils their grown, whereas they nearly have no significant correlations with the PH in their soils. This work was aimed to provide guidance for pollution-free vegetable base construction and heavy metal elements pollution control.
