DETERMINATION OF SUBSTITUTED POLYCYCLIC AROMATIC HYDROCARBONS IN URBAN AIR PARTICULATE MATTER.
Abstract
A method for quantitative determination of substituted polycyclic aromatics in air particulate matter is described based on liquid CO2-extraction, prefractionation on activated silica and gas chromatographic separation combined with neqative ion mass spectrometry. Results from winter and summer samples collected at St. Olavsgate, Oslo, are reported.
