• Polycyclic aromatic hydrocarbons (PAHs) were assessed in 65 atmospheric particulate matter (PM 10 ) samples collected at a coastal urban area of Southwest Atlantic Europe during the 1-year period. Analytical methodology was successfully validated in terms of limits of detection and quantification, linearity, precision and trueness by using ERM CZ100 reference material and analytical recovery studies. Status of PM 10 -bound PAHs and their relationship with other PM 10 constituents (major ions, trace metals, equivalent black carbon (eBC) and UV-absorbing particulate matter (UVPM)) in an area where few data are available is provided. Benzo(b)fluoranthene (BbF) and benzo(e)pyrene (BeP) were observed to be predominant in all samples analysed with average concentrations of 1.6 and 1.5 ng m −3 , respectively. Furthermore, high RSDs were achieved for PAHs during the sampling period, which reflects inherent heterogeneity of the atmospheric particles besides weather conditions variations. Statistical significant seasonal changes in PAH concentrations during summer and winter seasons were not found. Data obtained from molecular PAH indices, univariate analysis, principal component analysis (PCA) and cluster analysis (CA) suggested a pyrogenic origin derived from the continuous harbour activity and marine and road traffic emissions at the studied urban site throughout the year. Additionally, major ion and metal(oid) concentrations in PM 10 samples were also used as tracers of PAH origin and for PM 10 source exploration. Linear and quadratic models have shown that the PAH concentrations exhibited correlation with some metals (Ba, Bi, Cu, Pb, Sb and Zn) and NO 3 − concentrations. Finally, carcinogenic and mutagenic potencies and inhalation cancer risk (ILCR inh ) posed by PM 10 -bound PAHs were assessed.
