Straw mushrooms were grown on lead contaminated rice straw and stubble. Study materials were dried, acid digested, and analyzed for lead using flame atomic absorption spectrophotometry. The results showed the highest lead concentration in substrate was 445.350 mg kg⁻¹ in Treatment 3 (T3) and the lowest was BD (below detection) in Treatment 1 (T1). The maximum lead content in straw mushrooms was 5.072 mg kg⁻¹ dw in pileus of T3 and the minimum lead content in straw mushrooms was BD in egg and mature (stalk and pileus) stage of T1. The lead concentration in straw mushrooms was affected by the age of the mycelium and the morphology of mushrooms. Mushrooms' lead uptake produced the highest accumulation in the cell wall. Some lead concentrations in straw mushrooms exceeded the EU standard (>3 mg kg⁻¹ dw).
草菇在受铅污染的稻草和茬地上生长。研究材料经过干燥、酸消解，然后使用火焰原子吸收分光光度法分析铅含量。结果表明，处理 3（T3）中的基质中铅浓度最高，为 445.350 毫克/千克，处理 1（T1）中的最低值为未检出（BD）。草菇中铅含量最高的是 T3 菌盖中的 5.072 毫克/千克干重，T1 中菌蛋和成熟（菌柄和菌盖）阶段的铅含量最低，为未检出（BD）。草菇中的铅浓度受菌丝体年龄和蘑菇形态的影响。蘑菇对铅的吸收在细胞壁中产生了最高的积累。草菇中的一些铅浓度超过了欧盟标准（>3 毫克/千克干重）。
