|Abstract:||Semi-permeable membrane devices (SPMDs) have been deployed in high mountain areas (Central Pyrenees, Catalonia, Spain) for the measurement of atmospheric concentrations of hexachlorobenzene (HCB) and polychlorobiphenyls (PCBs) over a period of 1.5 years. These devices were filled with triolein and have been deployed at three altitudes, 1600, 2240 and 2600 m above sea level. Performance reference compounds were used to calibrate their sampling rates.|
The SPMD results were validated by comparison to active air sampling with high-volume systems. Sampling rates between 0.55 and 1.3 m3 d−1 were estimated from the dissipation of PCB155. Atmospheric concentrations measured by SPMDs were in good agreement with the levels obtained by high-volume sampling. These findings suggest that SPMDs can be useful monitoring systems for the atmospheric concentrations of organochlorine compounds in remote high mountain areas.
