The binding of organic contaminants to humin
- South Dakota State Univ., Brookings, SD (United States). Dept. of Chemistry and Biochemistry
It has been recognized for some time that a significant fraction of most organic contaminants that are introduced into a soil becomes rapidly and irreversibly bound to the humin fraction of naturally-occurring organic matter. The insolubility of humin in essentially any solvent has made the study of these bound residues difficult. The ability to fractionate humin into four components (extractable lipids, bound-humic acid, bound lipids, and mineral matter) using the methyl-isobutylketone partitioning procedure is providing new insights into the phenomenon of bound-residue formation and the fate of anthropogenic organic compounds in natural environments. Results will be presented describing the formation of PCB- and PAH-bound residues in humin using {sup 14}C-labeled compounds. The distribution of the radioactivity among the components of humin will be compared and contrasted.
