Seasonal variation in microplastic abundance, morphology, polymers, and adsorbed contaminants in wastewater treatment sludges and biosolids

This study investigated the seasonal impact on microplastic (MP) characteristics and concentration in the sludge streams (primary, secondary (waste activated) and digested) at a municipal wastewater treatment plant (WWTP) in Ontario. MPs were recovered after digestion and density...

Size and coating impacts on copper oxide nanoparticle transformations and toxicity to earthworms

Introduction: A key concern for the risk assessment of metallic engineered nanomaterials in the terrestrial environment is the degree to which particle size and functional coatings may alter particle dissolution transformations and subsequent toxicity and bioaccumulation effects....
