Abstract
This study aims to determine the concentration of 16 Polycyclic Aromatic Hydrocarbons (PAHs) in urban soils from Leeds in order to determine what the factors are controlling their distribution and abundances. Soil samples were collected across an area from Leeds. Gas chromatography with mass spectrometry (GC-MS) using selected ion monitoring (SIM) was used to identify and quantify PAHs in the soil samples with the aid of PAH external standards. The results showed the highest concentrations of total PAHs in sample L8 (1344 ng/g) taken from an area located near a parking site and road in Leeds and the lowest total concentration of the 16 PAHs in sample L16 (87 ng/g) taken from a private garden. The ratio of anthracene to anthracene plus phenanthrene AN/(AN + PH), fluoranthene to fluoranthene plus pyrene FLU/(PY+FLU) and benzo[a]anthracene to 228 (BaA/228) implied that the PAHs pollution originated from pyrogenic, biomass and petroleum combustion in the samples which were collected from Leeds city.
