Forest Filter Effect Revisited: First Evidence That Polycyclic Aromatic Hydrocarbon Metabolites Are Produced on Leaves by Biodegradation and Photodegradation.

ABSTRACT: Plants are considered "nature-based solutions" for the improvement of air quality. Through the so-called forest filter effect (FFE), they can remove both gas and particulate matter (PM) associated organic contaminants, such as polycyclic aromatic hydrocarbons (PAHs) from air, reducing their concentrations. In this work, new aspects of FFE were investigated through several laboratory experiments of increasing complexity. More specifically, the study was designed to evaluate for the first time the contribution of light and phyllosphere microbial communities of Quercus ilex leaves to the degradation of deuterated PAHs (naphthalene-d8, acenaphthene-d10, phenanthrene-d10, pyrene-d10, chrysene-d12, and perylene-d12). Such degradation was investigated by observing the production of deutera
