Silver nanoparticles (AgNPs) are among the engineered nanomaterials most often incorporated in nanofunctionalized consumer products, such as plastics, soaps, pastes, metals, and fabrics. These nanoparticles also have applications in water and soil remediation. Owing largely to a dearth of appropriate detection methods, concentrations of AgNPs in the aquatic environment have primarily been estimated through modeling, with predicted environmental concentrations in the ng/L range. This report documents the results of a 3-year project conducted to (1) develop and implement methods for the detection of AgNPs in water; (2) determine the toxicological properties and environmental fate of AgNPs in the aquatic environment; and (3) develop risk assessment protocols that can be used to evaluate the environmental fate of and likely risk from AgNPs in aquatic pathways. http://www.epa.ie/pubs/reports/research/health/Research_Report_259.pdf
