中文摘要：

以四种生物量大,易于栽培的蕈菌为材料,研究其对土壤中Pb和As的生物富集水平.干燥后的蕈菌样品经过微波消解处理,采用原子吸收分光光度法（AAS）分析蕈菌样品中的铅含量,采用电感耦合等离子体光谱法（ICP-AES）分析蕈菌样品中的砷含量.研究表明在污染土壤中收集的蕈菌样品中铅和砷的水平随着土壤中铅和砷浓度的增加而增加.当土壤中的Pb2＋浓度为1000mg/kg（DW）时,长根菇对Pb的积累能力最强,可达到13.33±1.44mg/kg（DW）.当土壤中的As3＋浓度为200mg/kg（DW）时,金福菇对As的积累能力最强,可达到9.34±0.21mg/kg（DW）.研究表明蕈菌对污染土壤中的铅和砷具有很强的积累能力.

英文摘要：

Lead and Arsenic bioaccumulation levels of four mushrooms which were of high biomass and easy to cultivate from contaminated soils were studied. Here, dried mushroom sample was prepared and after microwave digestion, the contents of Pb and As were determined by atomic absorption spectroscopy （AAS） and inductively coupled plasma atomic emission spectroscopy （ICP-AES）, respectively. The study indicated that the Pb and As levels of mushroom samples harvested from contaminated soils increased with increasing Pb and As concentrations in soils. The highest Pb concentration in mushroom sample harvested from soil 1000mg/kg Pb2＋ added was Collybia radicata （13.33±1.44 mg/kg, dry weight （DW））. The highest As concentration in mushroom sample harvested from soil 200mg/kg As3＋ added was Trichohnona lobyense （9.34±0.21 mg/kg, DW）. The study suggested that mushroom had a great ability to accumulate Lead and Arsenic from contaminated soil.
