freely dissolved concentration.
Freely dissolved concentrations of (highly) HOCs can be obtained.
Apart from containing total amounts, analysis by SPME provides information on the freely dissolved analyte concentrations.
CPDMS is proportional to the freely dissolved concentration (Cfree), chemical activity and also fugacity [6].
While only the freely dissolved OCCs are available to nd-SPME fiber, both the freely dissolved and the nC60 associated OCCs contributed to the accumulation of OCCs to medaka.
While the determination of freely dissolved concentrations has long been known to be laborious, SPME is suitable to distinguish freely dissolved and total concentrations and seems to be useful for various environmental and (eco toxicological investigations [17].
The 16 priority polycyclic aromatic hydrocarbon (PAH) concentrations of freely dissolved, total dissolved, and SPS-associated were determined.
A binding coefficient Kb was defined as the ratio between the concentration of phenanthrene associated to the AuNPCIT and that freely dissolved in the exposure medium.
With LLE, freely dissolved fractions are not distinguished from bound amounts of the analytes in more complex water samples (i.e., water samples with particulate and dissolved OM).
For that reason, the internal standards are also bound by OM, and a correction by internal standards would not lead to the freely dissolved concentration.
By quantifying concentrations of target analytes in the polymer of the sampler, freely dissolved concentrations (c free) are determined that are a measure of contaminant bioavailability.
