Hydrothermal versus photo-aged polyethylene microplastics: Aging mode-dependent oxidative stress and enzyme inhibition in waste activated sludge fermentation.
The aging of microplastics (MPs) inevitably occurs during sludge treatment, leading to the leaching of dissolved organic matter (DOM) and associated chemical additives. However, the impact and mechanism of aged leachate on anaerobic fermentation of waste activated sludge (WAS), particularly its ecological risks and imp...
