Particulate Nitro/oxy-PAHs size distribution and PAHs on sampling degradation in two sites around Paris

Abstract : Polycyclic aromatic hydrocarbons (PAHs) are emitted both in gas and particulate phases during incomplete combustions. Due to the mutagenicity and carcinogenicity of some of them, their monitoring is of prime interest. Particularly for the Benzo[a]pyren (B[a]P) which is commonly used as a tracer for this compounds family due to his high toxicity. B[a]P, which is present at 90% in particulate phase (
