摘要

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. (c) 2017 SETAC
