Sorption and bioaccumulation of neutral and ionizable wastewater-derived contaminants of emerging concern: exposure of edible crops via solid and liquid effluent streams
Diverse contaminants of emerging concern (CECs) are ubiquitous in waste streams. Batch sorption tests with sludge solids from wastewater treatment systems examined sorption to the solid phase of CECs during wastewater treatment. Compounds, including neutral, acidic and basic CECs, were evaluated for how sorptive behavior might differ for CECs in different states of charge. Sorption of CECs varied little between different sludges. Organic carbon normalized partition coefficients (log K[subscript oc]) were correlated with octanol-water partition coefficients (log K[subscript ow]) for nonionized ...
