Hoekstra PF, O'Hara TM, Karlsson H, Solomon KR, Muir DC: Enantiomer-specific biomagnification of alpha-hexachlorocyclohexane and selected chiral chlordane-related compounds within an Arctic marine food web. Environ Toxicol Chem. 2003 Oct;22(10):2482-91.
Concentrations of achiral and chiral organochlorine contaminants (OCs), including hexachlorocyclohexane isomers (HCH), chlordane congeners (cis- and trans-chlordane, cis- and trans-nonachlor, MC5, MC7, and U82), and related metabolites (oxychlordane [OXY] and heptachlor exo-epoxide [HEPX]), were quantified in seawater (100 L; n = 6) and biota from the coastal Beaufort-Chukchi Seas food web near Barrow (AK, USA). |

Huhnerfuss H, Faller J, Kallenborn R, Konig WA, Ludwig P, Pfaffenberger B, Oehme M, Rimkus G: Enantioselective and nonenantioselective degradation of organic pollutants in the marine ecosystem. Chirality. 1993;5(5):393-9.
Enantiomeric ratios of 11 chiral environmental pollutants determined in different compartments of the marine ecosystem by chiral capillary gas chromatography and chiral high-performance liquid chromatography allow discrimination between the following processes: enantioselective decomposition of both enantiomers with different velocities by marine microorganisms (alpha-HCH, beta-PCCH, gamma-PCCH); enantioselective decomposition of one enantiomer only by marine microorganisms (DCPP); enantioselective decomposition by enzymatic processes in marine biota (alpha-HCH, beta-PCCH, trans-chlordane, cis-chlordane, octachlordane MC4, octachlordane MC5, octachlordane MC7, oxychlordane, heptachlor epoxide); enantioselective active transport through the "blood-brain barrier" (alpha-HCH); nonenantioselective photochemical degradation (alpha-HCH, beta-PCCH). |
