absorbing the gaseous pollutants through leaf stomata during the normal exchange of gases. • binding or dissolving water soluble pollutants onto moist leaf surfaces. • intercepting and storing larger particulates on outer leaf surfaces, the epidermis, which may be waxy, resinous, hairy, or scaly. • capturing and storing particulates on the uneven, rough branch and bark surfaces.
• sequestering CO2 aboveground in woody tissue and belowground in the roots. • lowering local air and building temperatures through transpiration, shading, and reducing winter wind infiltration, thus lessening the demand for cooling and heating and the formation of ozone.
