摘　　要：目的研究安徽省某镇回收蓄电池土法炼铅所造成的环境污染,为铅污染防治提供依据。方法用石墨炉原子吸收光谱法测定融铅炉污染区环境（空气、小麦、土壤）的铅含量,并与对照区进行比较。结果污染区空气样品的铅含量为0.028±0.265mg/m^3,超过国家标准10倍;小麦样品铅含量为2.84±11.287mg/kg,超过国家标准7倍;土壤样品铅含量为0.0670±1.72%,超过国家标准2-3倍。对照组空气样品的的铅含量为0.0650±0.0527mg/m^3;小麦样品的铅含量为0.335±0.114mg/kg;土壤样品的铅含量为0.067%±0.00505%。结论污染区空气、小麦和土壤中铅含量都显著高于对照组,土法炼铅严重污染了环境。Objective Environmental pollution caused by lead smelting using recycled storage batteries in a town, in Anhui Province was investigated. Methods Lead content in air, wheat and soil of lead smelting furnace area was determined by atomic absorption spectrometry and the results were compared with the control. Results Lead content in air was 0.028 ±0. 265mg/m^3, which was ten times more than the national standard. Lead content in wheat was 2.84 ± 11. 287mg/ kg, which was fifteen times more than the national standard Lead content in soil was 0. 0670 ± 1.72%, which was twenty times more than the national standard; Lead content in air of the control was 0. 0650 ± 0. 0527mg/m^kg. Lead content in wheat was 0335 ± 0.114mg/kg. Lead content in soil was 0. 067% ± 0. 00505%. Conclusion Lead content in air, Wheat and soil of lead smelting furnace area were apparently higher than the control. It indicated that the environment of this area was seriously polluted by lead.
