Abstract

Biosolids from municipal treatment plants, and manure from livestock or poultry production are frequently used as fertilizer in crop production. These materials can contain human or veterinary pharmaceuticals and organic microconstituents that can pose a threat to the environment or to human health should they be transported to surface water or groundwater. Here, we consider field experiments defining the significance and mechanisms of transport of pharmaceuticals and personal care products (PPCPs) and veterinary medicines into runoff or into tile water. An emphasis is placed on experimental and analytical challenges, key rate controlling factors governing the fate of selected PPCPs, and the toxicological significance of mass loads and maximum aqueous concentrations of the exported residues. Information is provided provided on better management practices that reduce the risk of exposure after field applications of biosolids and manure.
