摘要
以广西某铅锌冶炼企业厂区周边土壤中的重金属为研究对象,采用土壤重金属累积模式预测由大气沉降至土壤中的重金属年变化趋势。根据预测结果,锌、铅最大累积贡献值点在项目投产20年后均满足《土壤环境质量标准》(GB15618-1995)二级标准的要求。
The soil contamination by heavy metals in the lead and zinc smelting enterprise of Guangxi was simulated. The change trend of soil heavy metals from atmosphere was forecasted by soil heavy metal accumulation model. Based on forecasted results, the largest cumulative contribution value of zinc and lead in the project will be less than the ＂soil environmental quality standards＂ （GB 15618-1995） second standards after the project putting into operation 20 years.
