Sector: Other Technologies n.e.c.
Country: India
Area of Application: The sampling system designed in this study is suitable for the investigation of airborne PAHs (with molecular weights of 202 and above) in the tropical climate since even at sampling temperatures of 35 deg C, none of the listed PAHs was traceable in the second layer of the XAD-2 adsorbent tube.
Keywords: Polycyclic Aromatic Hydrocarbons, PAHs
Advantages: The advantage of impactor sampling is to provide minimal contact of collected particulate matter with the air stream so that the particle blow-off effect can be kept to a minimum. Furthermore, cascade impactor sample provides particles over the inhalable size range. Beside, T60A20 appears to have superior filtering qualities because of its reduced surface activity. This may contribute to a redued degradation of collected PAHs during sampling and storage. XAD-2 adsorbent, as well, has several advantages un terms of collection efficiency, good recovery of adsorbed compounds and minimal degradation during storage.
