Source Apportionment of Atmospheric Polycyclic Aromatic Hydrocarbons Collected from an Urban Location in Birmingham, U.K.

摘要: Intensive seasonal sampling campaigns were undertaken at an urban location in Birmingham, U.K., which high-volume samplers used to collect particulate- and vapor-phase polycyclic aromatic hydrocarbons (PAHs) by means of filter papers polyurethane foam plugs. Eighteen PAH species determined reversed-phase HPLC. Additionally, the suspended particle loading air was measured gravimetrically. Dichotomous stacked units (DSFUs) run simultaneously with high-volumes enabling collection particulate matter representative fine (<2.1 μm) coarse sized (2.1−10 fractions. Filters from DSFUs analyzed for 19 metal [by proton induced X-ray emission (PIXE)], ammonium, elemental carbon, various anions. Metal concentrations observed be broadly line other areas throughout U.K. Chemical source apportionment studies took form principal component analysis (PCA) followed multi-line...
