volumetric concentration

Results of such aquatic toxicity testing are often expressed as volumetric concentrations.

Cg is the volumetric concentration of gas.

The review of IC50 data suggests that a volumetric concentration IC50 of 13% of the TME before it is discharged to the municipal wastewater collection system would generally ensure a non-toxic effluent.

Volumetric concentrations (mass per volume of wet sediment) more accurately portrayed the depth distribution of mercury in the lakes than did dry-weight concentrations, which underrepresented the significance of the shallow-water sediments as a reservoir of potentially available mercury.
