Polycyclic aromatic hydrocarbon source fingerprints in the environmental samples of Anzali—South of Caspian Sea

The major emission sources of polycyclic aromatic hydrocarbons (PAHs) in Anzali city, apportionment of these sources and transfer of PAHs through street dust and runoff to rivers and finally the Caspian Sea, were studied. PAHs in environmental samples including street dust, runoff, and river sedimen...
