Water Quality Guidelines for the Protection of Aquatic Life
Freshwater
Short Term Concentration (µg/L) NRG
NRG= no recommended guideline
This guideline is not applicable to silver nanoparticles.
CWQGs were derived based on the total concentration of silver.
Because the short-term SSD 5th percentile and the long-term SSD 5th percentile (CWQG) are essentially equal, no designated short-term freshwater benchmark is recommended.
Long Term Concentration (µg/L) 0.25
This guideline is not applicable to silver nanoparticles.
CWQGs were derived based on the total concentration of silver.
Date 2015
Marine
Short Term Concentration (µg/L) 7.5
This guideline is not applicable to silver nanoparticles.
CWQGs were derived based on the total concentration of silver.
Long Term Concentration (µg/L) NRG
NRG= no recommended guideline
This guideline is not applicable to silver nanoparticles.
CWQGs were derived based on the total concentration of silver.
There were insufficient data to derive a long-term marine guideline.
