Looking for Nanosilver in British Rivers A final report entitled
Exposure assessment for engineered silver nanoparticles
throughout the rivers of England and Wales (CB0433) was
published by the Centre for Ecology and Hydrology UK (CEH). The
report is the result of a year-long study of the concentration
of nanosilver particles in English and Welsh rivers and sewer
systems. The effect of nanosilver on the environment is not
known very well due to the fact that the concentration of it in
the environment is not known. The toxicity of nano- and
colloidal silver is high in high concentrations. This study
measured that concentration and compared it with the model based
on the commercial and residential use of nano-silver products.
In order to model the concentration of nano-silver in rivers a
Low Flows 2000 (LF2000) WQX (Water Quality eXtension) model was
used. This model is commonly used to model the river flows and
regional water resources. 'Based on our knowledge of their
consumption, predicted nano silver concen
