Previously we reported the development and evaluation of a high-volume air sampler for pesticides and other semivolatile industrial organic chemicals (1). This sampler has proved useful for monitoring airborne pesticides associated with agricultural applications (2) and polychlorinated biphenyl emissions from incineration and spill cleanup processes (3) Since our initial publication, the sampling system has been improved through redesign of the collection module for more efficient and versatile use. The new module accomodates a reusable sorbent cartridge which can be extracted intact for chemical analysis. Both polyurethane foam (PUF) and granular sorbents can be employed for sampling air at flow rates of 200-250 L/min. This correspondence describes the collection module and reports results of studies conducted to improve sampling efficiencies for more volatile compounds.
