Abstract

Atmospheric aerosols were collected during the period from May2000 through January 2001 at 13 different sites in and around the Baciacavallo sewage treatment plant in Prato (Italy). The urban area surrounding the plant contains significant textile industrial activityand a main arterial road. Aerosol-associated n-alkane, polycyclic aromatic hydrocarbon (PAH), nonylphenol (NP) and nonylphenolethoxylate (NPnEO) (n = 1,2,3) concentrations were measured in order to evaluate contributions from the sewage treatment plant, naturallyproduced aerosols, transportation and industrial activities to the air qualityin the vicinityof the sewage treatment plant. Aerosol-associated n-alkane concentrations ranged from 36.7 to 205 ng/m3 and their possible origin was determined bythe presence of typical petroleum characteristics such as the unresolved complex mixture and an odd/even carbon ratio (Carbon Preference Index). PAH concentrations ranged from 0.855 to 24.2 ng/m3 , in accordance with those generallyfound for urban aerosols in Europe. NP and NPnEO (n = 1,2,3), as well as fine aerosol particulate matter (PM10) were significantly correlated with relative wind direction with increased levels observed in the ambient atmosphere when the relative wind direction was from the Baciacavallo sewage treatment plant. This studyconfirms the use of NP and NPnEO (n = 1,2,3) as markers of sewage treatment emissions and the importance of the contribution of aerosols produced bysewage treatment plant aeration tanks to the local atmospheric composition.
