Abstract

The combined influence of oxygenation and salinity on agglomeration and/or aggregation kinetics of the silver (Ag) nanomaterial NM-300K was investigated, and the relationship between its physicochemical fate and toxicity toward an estuarine bivalve was established. The results showed that the presence of NaCl under certain oxygen conditions (8.5 ppm) promoted the formation of AgCl aggregates that could be linked to toxicity effects on aquatic organisms.
