The environmental impact of silver nanoparticles (AgNP) has become a topic of interest recently, this is due to the
fact that AgNPs have been included in numerous consumer products including textiles,medical products, domestic
appliances, food containers, cosmetics, paints and nano-functionalised plastics. The production, use and disposal
of these AgNP containing products are potential routes for environmental exposure. These concerns have
led to a number of studies investigating the release of particles fromnano-functionalised products, the detection
of the particles in the aquatic environment and the potential environmental toxicology of these AgNPs to aquatic
organisms. The overall aimof this review is to examine methods for the capture and detection of AgNPs, potential
toxicity and transmission routes in the aquatic environment.
