A sampling and analytical method for organophosphorus pesticides using a combined filter/XAD-2 sorbent sampler and gas chromatography (GC)-flame photometric detection (FPD) was developed. The method was evaluated for 19 organophosphorus pesticides based on the joint Occupational Safety and Health Administration/National Institute for Occupational Safety and Health Standards Completion Program methods evaluation protocol. The evaluation addressed analyte recovery, sampler capacity, sample stability, and precision and accuracy. Additional experiments addressed long-term sample stability (30-day storage), short-term exposure limits, limits of detection, and concentration levels down to 0.1 times an exposure limit value. Samples were stable for 30 days of storage under either ambient or refrigerated conditions. Based on this research, all 19 compounds studied can be successfully determined simultaneously using one method with an accuracy of +/- 25% of the true value 95 times out of 100.
开发了一种使用组合过滤器/XAD-2吸附剂采样器和气相色谱（GC）-火焰光度检测（FPD）的有机磷农药采样和分析方法。根据美国职业安全与健康管理局/美国国家职业安全与健康研究所标准完成计划联合方法评估协议，对19种有机磷农药的该方法进行了评估。评估涉及分析物回收率、采样器容量、样品稳定性以及精密度和准确度。额外的实验涉及长期样品稳定性（30天储存）、短期接触限值、检测限以及低至接触限值0.1倍的浓度水平。样品在环境条件或冷藏条件下储存30天均保持稳定。基于这项研究，所研究的所有19种化合物都可以使用一种方法成功同时测定，100次中有95次的准确度为真实值的+/-25%。
