In the context of biosolids utilisation in forestry, effects of sludge application on mushroom metal concentration were studied in six sites of maritime pine forests in the South-West of France. Municipal sludge were applied at a rate of 6 T dry matter per hectare. Edible mushrooms were collected two years after sludge application. As, Cd, Cu, Hg, Pb, Se and Zn concentrations were determined. Results showed a high variability for trace element concentrations in mushrooms collected from control areas. No significant correlation was found between soil parameters (pH and trace elements concentrations) and mushroom trace element concentrations. Even if the concentration of trace metals increased in the soils, sludge application did not affect As, Cu, Se and Zn concentrations in carpophores but slightly increased Cd, Pb and Hg concentrations on some sites. This effect is dependent on sludge type and sites.
在林业中生物固体利用的背景下，在法国西南部的六个滨海松树林地点研究了污泥施用对蘑菇金属浓度的影响。以每公顷6吨干物质的速率施用城市污泥。在污泥施用两年后采集可食用蘑菇。测定了砷、镉、铜、汞、铅、硒和锌的浓度。结果表明，从对照区域采集的蘑菇中微量元素浓度变化很大。未发现土壤参数（pH值和微量元素浓度）与蘑菇微量元素浓度之间存在显著相关性。即使土壤中微量金属的浓度增加，污泥施用也不会影响子实体中砷、铜、硒和锌的浓度，但在某些地点会略微增加镉、铅和汞的浓度。这种影响取决于污泥类型和地点。
