本研究通过实验室实验验证了极地有机化学综合采样器（POCIS）在自然灾害和水生环境事故造成的非稳态条件下的化学品监测能力。这项工作的目标是有助于监测紧急情况和自然灾害造成的化学污染的实际状态。在洁净室中建立了一个模拟水生环境化学污染的室，该室是通过化学暴露评估模型建立的。 7种新烟碱类农药的浓度增加至最高1,000、100或10微克/升，持续一天，此后每天减少50%。以聚醚砜作为渗透膜，以树脂（Oasis亲水亲油平衡）作为接收相，建立POCIS。还进行了 POCIS 的校准测试。这项研究的结果导致 POCIS 可测量目标清单中添加了六种新烟碱类农药。室内实验的结果表明，POCIS 是水生环境非稳态条件下化学品监测的良好工具。
This study validated the chemicals monitoring ability of a polar organic chemical integrative sampler (POCIS) under non-steady-state conditions resulting from natural disasters and environmental accidents in aquatic environments via laboratory experiments. The goal of this work was to contribute toward monitoring the actual state of chemical contamination resulting from emergencies and natural disasters. A chamber replicating the chemical contamination of an aquatic environment established by a chemical exposure assessment model was set up in a clean booth. The concentrations of seven neonicotinoid pesticides were increased to a maximum of 1,000, 100, or 10 μg/L for one day and decreased by 50% per day thereafter. A POCIS was set up with polyethersulfone as the permeation membrane and a resin (Oasis hydrophilic-lipophilic balance) as the receiving phase. Calibration tests of the POCIS were also conducted. The results of this study led to the addition of six neonicotinoid pesticides to the list of POCIS-measurable targets. The results of the chamber experiments showed that a POCIS is a good tool for chemicals monitoring under non-steady-state conditions in an aquatic environment.
