Passive sampling of atmospheric organochlorine compounds by SPMDs in a remote high mountain area
AbstractSemi-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 2600m 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 1.3m3d−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.
