Persistent Organic Pollutants (POPs) are anthropogenic chemicals extensively used in the past for industrial and agricultural purposes, characterized by their lipophilicity, ubiquity, volatility and environmental persistence. By other hand, chlorpyrifos is the most widely used current pesticide (CUPs) being the main insecticide used for crops in Argentina. The aim of this work was to assess levels of POPs and CUPs in different fractions of airborne particles collected indoor in agricultural areas from Argentina. Particles higher than 2.5 µm were trapped in polyurethane foams (PUF) while particles smaller than 1 µm and volatile compounds were adsorbed on activated charcoal. Compounds were analyzed by gas chromatograph with electron capture detector (GC‐ECD). Endosulfans, chlordanes, PCBs, and HCHs were detected in all PUF samples, while endosulfans, chlorpyrifos, PCBs, and HCHs were the most abundant in smaller particles. Majority of pesticides showed higher concentrations during the summer season (1397.7 vs 832.5 pg/m³). Even adding up all measured organic compounds, no sample reaches the threshold limit value for indoor pesticides levels (0.1 pg/m³), neither in the large or small particle fraction. However, the fact that chronic exposure to POPs has been linked to several diseases raises concern for human health.

阿根廷农业地区的室内持久性有机污染物。

持久性有机污染物（POPs）是过去人类广泛用于工业和农业目的的人为化学品，其特征是亲脂性，普遍性，挥发性和环境持久性。另一方面，毒死rif是目前使用最广泛的农药（CUPs），是阿根廷农作物的主要杀虫剂。这项工作的目的是评估阿根廷农业地区在室内收集的不同比例的空气传播颗粒中的POPs和CUPs的水平。大于2.5 µm的颗粒被困在聚氨酯泡沫（PUF）中，而小于1 µm的颗粒和挥发性化合物被吸附在活性炭上。通过具有电子捕获检测器（GC-ECD）的气相色谱仪分析化合物。在所有PUF样品中均检测到硫丹，氯丹，PCB和六氯环己烷，而硫丹，毒死rif，多氯联苯和六氯环己烷在较小的颗粒中含量最高。大多数农药在夏季表现出较高的浓度（1397.7比832.5 pg / m³）。即使将所有测得的有机化合物加起来，也没有任何样品达到室内农药水平的阈值极限（0.1 pg / m ³），无论是大颗粒还是小颗粒。但是，长期接触持久性有机污染物与几种疾病有关的事实引起了人们健康的关注。
