Abstract

Suspended particles with the aerodynamic diameters not greater than 2.5 μm (PM2.5) and 1 μm (PM1, sub-fraction of PM2.5) were sampled at three sites: an urban background site, rural background site, and urban traffic site in southern Poland. In total, there were 240 samples taken within 02.08.2009–27.12.2010. Fifteen polycyclic aromatic hydrocarbons (PAH) were determined in each dust fraction. The averages of the concentration of total PAH (ΣPAH) and of particular PAH, as well as the share of carcinogenic PAH in total PAH (ΣPAHcarc/ΣPAH), carcinogenic equivalent, mutagenic equivalent, and TCDD-toxic equivalent appeared high compared to other areas in the world. Their high values express the significance of health hazard from PM and PM-bound PAH in southern Poland. The diagnostic ratios suggest that PM-bound PAH originate from municipal (PM1−2.5) and vehicular (PM1) combustion.

Highlights

Suspended particles with the aerodynamic diameters not greater than 2.5 lm (PM2.5) and 1 lm (PM1, sub-fraction of PM2.5) were sampled at three sites: an urban background site, rural background site, and urban traffic site in southern Poland
The averages of the concentration of total polycyclic aromatic hydrocarbons (PAH) (RPAH) and of particular PAH, as well as the share of carcinogenic PAH in total PAH (RPAHcarc/RPAH), carcinogenic equivalent, mutagenic equivalent, and TCDDtoxic equivalent appeared high compared to other areas in the world
Diurnal samples of PM1 and PM2.5 were collected at three sites in southern Poland: urban background (UB) and urban traffic (UT, urban site directly affected by road traffic) sites in Katowice, and a regional background site (RB) in Złoty Potok

Summary

Introduction

Suspended particles with the aerodynamic diameters not greater than 2.5 lm (PM2.5) and 1 lm (PM1, sub-fraction of PM2.5) were sampled at three sites: an urban background site, rural background site, and urban traffic site in southern Poland. The goal of the presented work was to investigate the ambient concentrations of fifteen PM1- and PM2.5-bound PAH (Acy, Ace, F, Ph, An, Fl, Py, BaA, Ch, BbF, BkF, BaP, DBA, BghiP, IP)1 at three sites, each representing one specific situation in air pollution in southern Poland.
