Benzopyrene Sampling System
Polycyclic aromatic hydrocarbons (PAHs) are omnipresent ambient air pollutants. These pollutants are generated from the incomplete combustion of organic (carbonaceous) material.
Their occurrence in the ambient air has been substantial during the past centuries due to emissions from industrial processes and energy production, motor vehicular traffic, incineration of refuse, and residential heating.
There is considerable concern about the relationship between PAH exposure in the ambient air and the potential to contribute to human cancer incidence.
About 500 different PAHs have been detected in air, but often the measurements focus on benzo[a]pyrene (B[a]P) as a representative of the whole PAH family.
Benzo[a]pyrene ( as other PHAs) may be found both in the gas and the particulate phase of ambient air or in mixtures of both phases.
Benzopyrene ( & other PHAs) dispersed in the ambient air becomes integrated with other particulates. Sampling for Benzopyrene ( & other PHAs) is carried out as integrated sampling for all particulates and is not carried out separately. The Benzopyrene ( & other PHAs) components are analysed after collection of the samples through a number of techniques.
A High Volume Sampler is generally employed for this purpose though the selection of the sampler will be dictated by the object of sampling and other considerations.
All our PM samplers can be used for this purpose.
