菜地土壤铅、镉有效态与生物有效性研究
Study on the Available and Bioavailability of Lead and Cadmium in Soil of Vegetable Plantation
摘要
Abstract
Through field sampling and test in lab.,the contents of available and bioavailability of lead and cadmium in soil of vegetable plantation in Beibei district of Chongqing were analyzed.The results showed that： In the study area,the average contents of the available of lead and cadmium were 3.114,0.051 mg/kg of vegetable plantation,the biological validity coefficients were 7.7%,25.1%;The average contents of the lead,cadmium in cabbage edible part was 0.123,0.021 mg/kg,the enrichment indexes were 0.4%,9.8%;from the enrichment and the bioavailability indexes,the potential ecological risk of cadmium was larger than the lead in soil of vegetable plantation.In study area,the soil properties of pH affected on the available of cadmium in significant;and the clay and organic matter affected on the available of lead in significant;the available of lead and cadmium with the total change of the same,full amount was available contents of the main effects factors;The type of soil also affected the available contents of the lead and cadmium;and traffic affected the available contents of lead and application of fertilizers affected the available contents of cadmium in human activities.The correlation between the available of lead,cadmium in soil of vegetable plantation and cabbage edible parts of lead,cadmium was better than the whole amount of lead,cadmium in soil,making the contents of available of lead,cadmium indicate the ecological risk was more accurately.关键词
