Therefore, the use of these experimental techniques can make a significant contribution to the assessment of contaminant risk at polluted sediment sites. Quantification and separate consideration of AOC and BC materials in sediment may also result in more accurate assessment of risk. However it appears that nonlinear Freundlich sorption isotherms to BC should not be extrapolated to the very low free aqueous concentration range as this appears to overestimate the sorption strength.","divisions":[{"label":"title","span":{"begin":0,"end":52}}],"tracks":[]}
