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 Ag.

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 Ag.

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 Ag.

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 Ag.

There were insufficient data to derive a long-term marine guideline.
