The effects of Phanerochaete chrysosporium on the bioavailability of multiple heavy metals (Pb, Cd, Cu, and Zn) in river sediments were investigated by co-composting with the agricultural waste. The results showed that the Phanerochaete chrysosporium inoculation can greatly enhance the passivation on Cu, Pb and Cd during 60 days co-composting. The effects in the three metals followed the order: Cu > Cd > Pb. There were no differences for Zn whether inoculation with P. chrysosporium or not. Redundancy analysis (RDA) implied that more than 4/5 of the variation of all fractions data for all heavy metals was explained by all significant canonical axes. P. chrysosporium can change the significant parameters for each metal and enhance the explanatory power of RDA model. The inoculation can strengthen the effect of OM (organic matter) on the bioavailability of heavy metals, but weaken the contribution of pH.
研究了与农业废弃物共堆肥时，糙皮侧耳（Phanerochaete chrysosporium）对河流沉积物中多种重金属（Pb、Cd、Cu 和 Zn）生物有效性的影响。结果表明，糙皮侧耳接种可大大增强 Cu、Pb 和 Cd 在 60 天共堆肥过程中的钝化作用。三种金属的效果顺序为：Cu＞Cd＞Pb。是否接种糙皮侧耳对 Zn 没有影响。冗余分析（RDA）表明，所有重金属所有分数数据的变化中有超过 4/5 可以用所有显著典型轴来解释。糙皮侧耳可以改变每种金属的显著参数，并增强 RDA 模型的解释能力。接种可以增强 OM（有机物）对重金属生物有效性的影响，但会削弱 pH 的贡献。
