摘要

The recent economic crisis in Greece resulted in a serious wintertime air pollution episode in Thessaloniki.This air quality deterioration was mostly due to the increased price of fuel oil,conventionally used as a source of energy for domestic heating,which encouraged the residents to burn the less expensive wood/biomass during the cold season.A wintertime sampling campaign for fine particles (PM_(2.5)) was conducted in Thessaloniki during the winters of 2012 and 2013 in an effort to quantify the extent to which the ambient air was impacted by the increased wood smoke emissions.The results indicated a 30% increase in the PM_(2.5) mass concentration as well as a 2-5-fold increase in the concentration of wood smoke tracers,including potassium,levoglucosan,mannosan,and galactosan.The concentrations of fuel oil tracers (e.g.,Ni and V),on the other hand,declined by 20-30% during 2013 compared with 2012.Moreover,a distinct diurnal variation was observed for wood smoke tracers,with significantly higher concentrations in the evening period compared with the morning.Correlation analysis indicated a strong association between reactive oxygen species (ROS) activity and the concentrations of levoglucosan,galactosan,and potassium,underscoring the potential impact of wood smoke on PM-induced toxicity during the winter months in Thessaloniki.
