Abstract:

This study examined the response of several particulate monitoring instruments to aerosols which might be encountered during monitoring of an in situ oil spill burn. Aerosols included road dust, salt, and particulates from the combustion of heptane, diesel fuel, and crude oil. Different sampling heads, including Total Suspended Particulates, 10 mum cutoff (PM-1O), and 2.5 mum cutoff (PM 2.5), were used with each instrument. Both optical cell and gravimetric instruments reported similar concentrations of aerosols generated by combustion of crude oil, diesel fuel, or heptane. For the road dust and salt aerosols, gravimetric monitors reported mass concentrations two to three time higher than the values recorded by the optical cell instruments.
