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.
在本研究中，我们报告了用于有机扩散梯度薄膜（o-DGT）和极性有机化学整合采样器（POCIS）的药物和农药的冷冻储存稳定性。大约 18 个月后，30 种化合物中 o-DGT 的平均变化为 9 ± 9%。对于 POCIS，在大约 6 年后，相同化合物的平均变化为 14 ± 14%。我们的数据表明，储存在这些采样器上的分析物是稳定的，适合存档。环境毒理化学 2018；37:762-767。©2017 SETAC。
