摘要
研究了城市固体废物对阿布贾市内牧草和土壤样品中镉、铜、镍、铅和锌含量的影响。采用火焰原子吸收分光光度法测定金属。牧草样品中Cd、Cu、Ni、Pb和Zn的平均浓度分别为0.3±0.1、3.8±1.2、2.9±0.8、50.7±14.3和34.7±6.1µg g -1 kg。土壤中金属含量高于牧草样品，Pb> Zn > Cu > Ni> Cd，重金属含量高于普通农田。土壤样品中的Cd和Pb含量高于许多国家土壤标准的水平，这表明城市垃圾是造成牧草和土壤样品中金属浓度的重要原因。关键词:固体废物，痕量金属，环境样品环境科学，Vol.3(1&2) 2004: 65-69
Impact Of Municipal Solid Waste On Trace Metal Concentrations In Herbage And Soil Samples Of The Abuja Municipality
The impact of municipal solid waste on the levels of cadmium, copper, nickel, lead and zinc in herbage and soil samples within Abuja municipality was studied. The flame atomic absorption spectrophotometry was used in the determination of the metals. The average concentration of Cd, Cu, Ni, Pb and Zn in the herbage samples were 0.3 ± 0.1, 3.8 ± 1.2, 2.9 ± 0.8, 50.7 ± 14.3 and 34.7 ± 6.1 µg g -1 weight respectively. The concentrations of metal in the soil were higher than in the herbage samples and were in the order of Pb> Zn >> Cu > Ni> Cd. The concentrations of metal in the soil samples were higher than levels in normal farmlands. The levels of Cd and Pb in the soil samples were higher than levels in soil criteria of many countries suggesting that municipal wastes are contributing significantly to the metal concentrations in the herbage and soil samples.
