【摘要】 采用环境调查的方法研究了涪陵南沱镇茎瘤芥种植基地土壤重金属含量。结果表明,该区域土壤整体上重金属污染水平较低,基本没受到汞和铬污染,但已受到了铜、铅、镉污染,特别是镉污染已经相当严重。相关分析和回归预测分析均表明土壤养分对土壤重金属含量有较大影响。更多还原

【Abstract】 Methods of environmental investigation were adopted to study the contents of heavy metals in the soil at the tumorous stem mustard cultivation base in Nantuo, Fuling. Contents of heavy metals were low in the region. Mercury and chromium contamination was virtually not present, while contamination by copper, lead and cadmium was detected, of which cadmium contamination was quite serious. Correlation and regression analyses showed that soil nutrients contributed substantially to heavy metal contents in the soil.更多还原
