Monitoring chronic and acute PAH atmospheric pollution using transplants of the moss Hypnum cupressiforme and Robinia pseudacacia leaves

AbstractFew studies are focused on correlations between the concentrations of PAHs in mosses and other bioindicator plant species. This study was carried out to investigate the potential of the joint use of devitalized H. cupressiforme transplants and R. pseudoacacia leaves as cost effective biomonitors for the assessment of PAHs in the air. The test was performed in a land historically devoted to agriculture, where recurrent waste burnings randomly occur, especially in the season we chose for the investigation. The presence of 20 PAHs was assessed following EPA 3550 C 2007 and EPA 8270 D 2014 protocols. R. pseudoacacia was able to accumulate both LMW and HMW PAHs, while moss prevalently collected the latter. It is suggested that R. pseudoacacia combined chronic pyrogenic and petrogenic PAH inputs, while moss transplants reflected PAH depositions from recent pyrogenic events. Our approach revealed long and short-term pollution footprints, with R. pseudoacacia recording the chronic input of PAH compounds loaded along its vegetative growth, and moss bags reflecting acute pollution inputs occurred during the exposure duration.
HighlightsRelations between PAH contents in H. cupressiforme and R. pseudoacacia were studied.R. pseudoacacia was able to accumulate LMW and HMW PAHs while moss prevalently HMW.Locust tree combined chronic PAH inputs, while moss reflected PAH recently emitted.
