Organic micropollutants (MPs) pose potential threats to environmental ecosystems and human health. This study investigated uptake of perfluoroalkyl substances (PFASs), pharmaceuticals, and paraben by edible oyster mushrooms (Pleurotus ostreatus), cultivated on spiked growth substrate. Concentrations of pharmaceuticals and paraben in substrate showed a decreasing trend over a 20-day harvesting period, whereas PFAS concentrations were variable over the harvesting period. However, only propylparaben, clarithromycin, and PFASs were detected in fruiting bodies of oyster mushroom. Uptake of PFASs by oyster mushroom fruit bodies was negatively correlated with perfluorocarbon chain length. An impact of MPs on fungal colonization was observed, with decreased respiration in treatments with the highest concentration of MPs, but production of fruiting bodies was not affected by exposure level. The potential human risk from ingestion of MPs was evaluated for oyster mushrooms exposed to the highest concentration of MPs in substrate, based on acceptable daily intake (ADI).
有机微污染物 (MPs) 对环境生态系统和人类健康构成潜在威胁。本研究调查了在添加生长基质上栽培的可食用牡蛎蘑菇 (平菇) 对全氟烷基物质 (PFASs)、药物和对羟基苯甲酸酯的吸收情况。在 20 天的收获期内，基质中药物和对羟基苯甲酸酯的浓度呈下降趋势，而 PFAS 浓度在收获期内变化不定。然而，只有丙酸对羟基苯甲酸酯、克拉霉素和 PFASs 被检测到在牡蛎蘑菇的子实体中。牡蛎蘑菇子实体对 PFASs 的吸收与全氟碳链长度呈负相关。观察到 MPs 对真菌定殖的影响，在 MPs 浓度最高的处理中，呼吸作用下降，但暴露水平对产菇量没有影响。根据可接受日摄入量 (ADI)，评估了在基质中 MPs 浓度最高的情况下摄入 MPs 对人体的潜在风险。
