Source Apportionment of Organic Pollutants of a Highway-Traffic-Influenced Urban Area in Bayreuth (Germany) Using Biomarker and Stable Carbon Isotope Signatures

摘要: Traffic- and urban-influenced areas are prone to enhanced pollution with products of incomplete combustion fossil fuels biomass such as black carbon or polycyclic aromatic hydrocarbons (PAHs). Black is composed graphitic structures may act a carrier for pollutants PAHs heavy metals. However, little known about possible contributions traffic-derived the inventory in soils. Similar uncertainties exist regarding contribution different pollutant sources total PAH contents. Therefore, objective this study was quantify importance traffic inventories contamination soils adjacent major German highway urban area Bayreuth 50 000 vehicles per day same order magnitude compared highway-close reported other studies. Using molecular (black PAHs) compound-specific stable i...
