This document summarizes a presentation on emerging organic contaminants found in biosolids. It discusses various categories of contaminants like pharmaceuticals, hormones, and personal care products that are present in wastewater and can accumulate in biosolids during treatment. It outlines principles of how these contaminants behave when biosolids are applied to agricultural lands, such as sorption, degradation, volatilization, and plant uptake. Models for predicting contaminant transport and quantitative structure-activity relationships are also mentioned as tools to help assess risks from emerging contaminants in biosolids.
