采用火焰和石墨炉原子吸收光谱法测定了土耳其托卡特土壤、蘑菇和植物样品中重金属的含量。对样品前处理方法的研究表明，微波消解法是最佳的样品前处理方法。通过对标准参考物质的分析，保证了良好的准确度。所有测量的金属浓度的相对标准偏差均低于10%。在所有情况下，定量分析回收率范围为95至103%。蘑菇和植物样品的金属积累因子进行了计算。高比例的植物土壤镉，锌和铜的浓度表明，这些元素积累的蘑菇。所得结果与文献报道的数据一致。(C)2003 Elsevier Science B.V.保留所有权利。
The concentrations of heavy metals in the soil, mushroom and plant samples collected from Tokat, Turkey have been determined by flame and graphite furnace atomic absorption spectrometry after dry ashing, wet ashing and microwave digestion. The study of sample preparation procedures showed that the microwave digestion method was the best. Good accuracy was assured by the analysis of standard reference materials. The relative standard deviations for all measured metal concentrations were lower than 10%. In all cases, quantitative analytical recoveries ranging from 95 to 103% were obtained. Metal accumulation factors were calculated for mushroom and plant samples. High ratio of plants to soil cadmium, zinc and copper concentrations indicate that these elements are accumulated by mushrooms. Results obtained are in agreement with data reported in the literature.
