We used a Mode l PS-1 PUF Sampler (Graseby GMW, Village of Cleves, OH, USA) to collect samples of total suspended particulate and n-alkanes in the gas phase. Particles were collected on quartz fiber filters. Gaseous n-alkanes were adsorbed by PUF and XAD-2 in a cartridge placed downstream of the filter holder in the sampler.
