In this work the leaf surface functional traits, potentially useful for air phytoremediation of particulate matter (PM) and polycyclic aromatic hydrocarbons (PAH), 28 woody species have been characterized, role these stomata, trichomes cuticle traits in assessed looking at existing correlations with species-specific ability to sequester retain airborne pollutants. Leaves were sampled urban area August September measured using Scanning Electron Microscopy Fourier-transform infrared spectroscopy. Pollutants extracted by leaves their concentrations daily uptake rates gas chromatography. Significant differences found between arrangement Correlations variables studied means principal component analysis. The trichomes-related scaled positively PM concentration uptake, whereas PAH phytoremediation, physical chemical features are relevant. Trichomes increase several fold providing extra surfaces retention, while thickness esterification regulate retention translocation subcuticular tissues. Results provide novelty on relationships plant potential, outlining an innovative way measuring traits. addition broadening economic spectrum it is emphasized how important nature-based solutions definition planning.
