Pharmaceuticals and pesticides archived on polar passive sampling devices can be stable for up to 6 years

Abstract

 

In the present study, we report the freezer storage stability of pharmaceuticals and pesticides for the organic‐diffusive gradients in thin‐films (o‐DGT) passive sampler and the polar organic chemical integrative sampler (POCIS). The average change on o‐DGT after approximately 18 mo was 9 ± 9% across 30 compounds. For POCIS, the average change after approximately 6 yr was 14 ± 14% for the same compounds. Our data suggest that analytes stored on these samplers are stable and appropriate for archival purposes. Environ Toxicol Chem 2018;37:762–767. © 2017 SETAC
