Field comparison between moss and lichen PAHs uptake abilities based on deposition fluxes and diagnostic ratios

In the present work, PAH uptake ability was tested in oven-devitalized moss (Hypnum cupressiforme) and lichen (Pseudevernia furfuracea) exposed in bags for six weeks in 9 periurban sites of Campania region (southern Italy). Based on a previous pilot work, aims of the study were to verify: i) whether...
