Augusto, S./ M. J. Pereira/ C. Máguas/ C. Branquinho 2013: A step towards the use of biomonitors as estimators of atmospheric PAHs for regulatory purposes. - Chemosphere 92(5): 626-632. [RLL List # 232 / Rec.# 34893]
Keywords: Air/ BaP/ Biomonitors/ Environment/ Human health/ PAHs
Abstract: One of the main drawbacks of using lichens to monitor atmospheric PAHs has been reported as the inexistence of studies aiming to translate PAH values in lichens into the atmospheric equivalents ones, in order to use this information for regulatory purposes. In this work, PAH concentrations in lichens were compared with PAH concentrations measured in a conventional active sampler in an outdoor environment for a 9-month span. Significant positive correlations between HMW-PAHs, ?16 EPA-PAHs, and BaP equivalent concentrations in lichens and those in air (TSP) were found. Concentrations of ?16 EPA-PAHs in lichens and air showed a seasonal variation, with highest values during winter and lowest values during summer. Meteorological variables
