In this study, the occurrence and diffusive air-water exchange of POPs in Panguipulli Lake (39º42'S-72º13'W), an oligotrophic lake located in northern Patagonia (Chile), were determined. Air and water samples were collected between March and August 2017 (autumn-winter) and analyzed for concentrations of OCPs (α-HCH, β-HCH, γ-HCH and HCB) and PCBs (PCB-28,-52,-101,-118,-153,-158,-180) using gas chromatography coupled with an electron capture detector. The direction of air-water exchange direction was evaluated using a fugacity approach (ƒ ƒ), and net diffusive exchange fluxes (F, ng m d) were also estimated. Read More
