In the present work, replicated estuarine mesocosm systems were
used to assess the leaching and fate of silver from CPs. Mesocosm environmental
compartments, which included seawater, intertidal sediment,
and biofilms, and organisms, namely hard clams, shrimp, and
snails, were sampled as a function of time and mesocosm treatment
over a period of 60 d. Inductively coupled plasma mass spectrometry
(ICP-MS) was used to determine the total mass fraction of silver in
each compartment at each collection time. In this way, estimates of
the overall effects of discarding nanosilver CPs into an estuarine environment
can be gauged to develop risk assessment models and remediation
strategies.
