Indoor persistent organic pollutants in agricultural areas from Argentina

Abstract

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.

Polybrominated Dibenzo-p-dioxins/Furans (PBDD/Fs) and Diphenyl Ethers (PBDEs) in the Indoor and Outdoor of Gymnasiums

“…Based on the current global data in Table 4, it was claimed that not many studies were addressed 291 PM2.5-bound PBDEs in the outdoor and indoor environment (Beser et al, 2014;Wang et al, 2014;292 Li et al, 2015;Xu et al, 2015;Chao et al, 2016;Deng et al, 2016;Liu et al, 2016;Xu et al, 2016;293 Guo et al, 2020;Tames et al, 2020). According to the current data, it is very difficult to conclude 294 whether indoor levels of PM2.5-bound PBDEs are higher or lower than outdoor levels of PM2.5-295 bound PBDEs or indoor and outdoor PM2.5-bound PBDEs are highly correlated.…”

Metal oxide/chitosan composite for organic pollutants removal: A comprehensive review with bibliometric analysis

“…Some of the pollutants are accumulated in the water that surpass the safe limit [1]. Organic pollutants can come from the natural environment and biological processing [2], to various industries that are increasing rapidly, such as agriculture [3] and textile industries [4]. Some of these organic pollutants include pharmaceutical waste, pesticides, dyes, and common organic chemicals.…”
