【摘要】 用原子吸收分光光度法研究了潮州市西湖沉积物中的铜、锌、铅、镉、锰、镍、镁、钙等金属元素的含量及分布规律。结果表明,铜、铅、锌、镉和镍是主要的重金属污染物,沉积物中5种重金属的平均含量为:铜584.7 mg/kg,铅149.1 mg/kg,锌360.9 mg/kg,镉1.2 mg/kg,镍76.7 mg/kg,均高于我国土壤背景值。更多还原

【Abstract】 The distribution and content of copper,zinc,lead,cadminum,manganese,nickel,magnesium and calcium in bottom sediments of the west Lake in Chaozhou were determinated by atomic absorption spectrometry.The results Show that Cu,Pb,Zn,Cd and Ni are the main heavy metal pollutants.The average content of the five kinds of heavy metal in sediments is as follows :Cu 584.7 mg/kg,Pb 149.1 mg/kg,Zn 360.9 mg/kg,Cd 1.2 mg/kg and Ni 76.7 mg/kg,respectively,which exceed the average background value of the soil of our country.更多还原
