Model No. APM 856 - Organic Vapor Sampler APM 856
Recent addition of Benzene in petrol, in place of a lead compound, has made Benzene and its derivatives a part of vehicular pollution. Already Benzene concentrations in high traffic areas and near petrol pumps have become a matter of concern. Unfortunately a majority of these compounds are highly toxic and many have been reported to be carcinogenic. Organic compounds are also reported to be pre-cursers for Ozone formation and play a role in secondary formation of oxidants. As such air pollution monitoring networks are now beginning intensive efforts for monitoring of specific organic compounds such as Benzene, Toluene & Xylene and often a mixture of Total Non Methane Hydrocarbons.
