Enrichment Characteristics Analysis and Assessment on Heavy Metal Contamination of Different Vegetables
摘要
Abstract
This research appliedsingle factor and comprehensive contaminant index methods to analyze the heavy metal accumulation characteristics of 17 vegetable species in order to ensure the safety of vegetable production and safe utilization of agriculture soils. The results of heavy metals pollution evaluation showed that, 4 vegetables: Shuidong leaf mustard (Brassica juncea (L.) Czern. et Coss.), Dapingpu more pulp leaf mustard (Brassica juncea(L.) Czern. et Coss.), Dapingpu late leaf mustard (Brassica juncea(L.) Czern. et Coss.), and Nanpanzhou late white radish (Raphanus sativus) were in security; 8 vegetables: Sijiu No.31 Chinese flowering cabbage (Brassica campestris L. ssp.chinensisvar.utilis Tsen et Lee), 70 days Chinese flowering cabbage (Brassica campestris L.ssp.chinensisvar.utilis Tsen et Lee), No.31 sweet Chinese flowering cabbage (Brassica campestris L. ssp.chinensisvar.utilis Tsen et Lee), Yutu No.5 Green stem chinese cabbage (Brassica pekinensis Rupr.), Ruyi chinese cabbage (Brassica pekinensis Rupr.), Beijing No.56 chinese cabbage (Brassica pekinensis Rupr.), Snow pea(Pisum sativum), and Short leaf No.13 white radish (Raphanus sativus) were near the warning limit; 2 vegetables: 60 days Chinese flowering cabbage (Brassica campestris L.ssp.chinensisvar.utilis Tsen et Lee), and green soy bean (Glycine max) were slightly polluted; 2 vegetables: Heat-resisting leaf lettuce (Lactuca sativa var longifoliaf. Lam), and Green stem spinach beet (Beta vulgaris L.) were moderately polluted; and 1 vegetable: Corainder (Coriandrum sativum L.) was heavily polluted. Therefore, the 4 vegetables in security can be used in safety production. Factor analysis showed that Cd was the main contaminant of the tested vegetables. For the heavy metal accumulation in vegetables, Cr had the greatest variation coefficient and then was Cd, while the accumulation of Pb, Hg, and As had little variation. From the view of heavy metal enrichment factor, white radish 1 (Nanpanzhou late white radish) had the lowest accumulation ability for Cr, Cd and Pb; leaf mustard 1 (Shuidong leaf mustard) had the lowest accumulation ability for As; while 2 kinds of beans (Snow pea and green soy bean) and 2 kinds of white radishes (Nanpanzhou late white radish and Short leaf No.13 white radish) had the lowest accumulation ability for Hg. These vegetable species and varieties could be used for future screening of low heavy metal accumulation vegetables.关键词
