【摘要】 为了调查重庆市郊几个蔬菜基地土壤的锌含量的情况,通过对市郊几个蔬菜基地的土壤进行了采样分析,分析其pH值,ω(Zn)的有效态、全态及污染物来源,从3个指标之间的关系来分析判断在不同地区锌污染的程度。调查表明不同地区的土壤锌含量不同,都有不同程度的锌富集,pH值对锌有效态有很大的影响。更多还原

【Abstract】 In order to investigate zinc of the soil of suburban vegetable districts in Chongqing,the papar analysed pH ,effective zinc,all zinc of the soil and pollutant resources. Zinc pollution extents in different districts were determined through the relation of three factors.
