摘　　要：采用原子吸收分光光度计,用浓缩火焰原子吸收法,检测南昌经济开发区周边环境中土壤及地表水中铜、镉、铬、铅四种重金属的含量,该方法简单快捷有效,灵敏度高,干扰少,对样品的测定结果满意。实验结果表明:所测土样中除农田用地的镉和铅未符合土壤环境质量二级标准,其他均达标,水样根据地表水环境质量标准,其中的镉、铬、铅均受到不同程度污染。The content of four heavy metals like Copper,Cadmium,Lead,and Chromium in soil and surface water surrounding Nanchang Economic Development Zone was detected and analyzed by atomic absorption spectrophotometer and concentrated flame atomic absorption spectrometry. This method is simple,effective,high sensitivity,less interference,and with satisfactory results. The experimental data showed that the measured soil reached the standard except the Cadmium and Lead in farmland which had not conformed to the second level criterion of Standard of Soil Environment. According to the surface water environmental quality standard,Cd,Cr,and Pb in water samples were polluted in different degrees.
