Abstract

Abstract: 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). Graphical abstract: Image 1 Highlights: Uptake of organic micropollutants (MPs) by edible oyster mushrooms was studied. PFAS uptake was negatively correlated with perfluorocarbon chain length. Oyster mushrooms displayed potential to degrade MPs. Decrease of respiration was observed at the highest MP concentration tested. Potential risks to humans from MP uptake in mushrooms was evaluated.
