title: [Levels of polycyclic aromatic hydrocarbons (PAHs) in air samples in the city of Arezzo (1997-1998)].
abstract: Polycyclic aromatic hydrocarbons (PAHs) are widely distributed environment pollutants of air, water and soil. Since many PAHs are potent mutagens and/or carcinogens the occurrence of these compounds in the lower atmosphere is an important element of environmental pollution. We measured PAH levels in airborne particles collected in the town of Arezzo, (Tuscany, Italy), during the period April 1997-February 1998. Air monitoring for 24 h was repeated for 7 days, during two weeks, in each season; a total of 84 air samples were obtained sampling two urban sites where the traffic is the main source of pollution. One site is a residential area. The data of this study indicate a pronounced seasonal variation in PAH levels and show that in cold spells other sources of contamination besides vehicular traffic are important.
