Descripción
Seasonal trend of polycyclic aromatic hydrocarbons (PAHs) associated with PM10 particles was assessed in an urban area in Cordoba, Argentina, during 2011-2013. In addition, we quantified the contribution of temperature, relative humidity, rainfall, atmospheric pressure and wind speed on total and individual PAH concentrations. Mean PAH concentrations were higher during autumn and winter. Temperature was the meteorological parameter that affected the most total and individual PAHs. Its influence was stronger in lightweight than in heavy PAHs, since they are more easily partitioned in the vapor phase. We found also that temperature has a lagged effect on PAHs concentration with the strongest association observed with 2-day lag temperature. Wind speed and relative humidity were also significant predictors for both light and heavy PAHs. Despite the fact that we observed a decreasing trend in the concentration levels of PAHs, they are still high enough to pose a risk to human health due to chronic exposure.
