Chromatographic enantiomer separation of chiral xenobiotics and their metabolites--a versatile tool for process studies in marine and terrestrial ecosystems.

A review discussing methodical aspects of enantioselective chromatographic separation of chiral environmental xenobiotics as well as examples for process studies reported in literature. The process studies include microbial transformation of chiral pollutants in aquatic ecosystems, their enzymatic transformation in biota, their photochemical degradation, air/sea exchange processes and atmospheric long range transport, and enantioselective toxic effects.
