Impact/Purpose:
To determine the environmental occurrences, fate, and effects of the enantiomers of selected chiral pesticides and other chiral pollutants.
Description:
Up to 25% of all pesticides are chiral; that is, they exist as two mirror image isomers called enantiomers. It is known that enantiomers usually differ in their biological properties through their differential interaction with enzymes or other naturally occurring chiral molecules. This may lead to differences in microbial degradation rates, which would mean that one enantiomer is more persistent in the environment than the other. Comprehensive risk assessments require a combination of exposure data with effects factors; therefore, it is desirable to assess enantiomer selectivity for both exposure and effects.
