Atmospheric constituents may be deposited to and incorporated into plant leaves, with gases entering via stomata, gas particles being sorbed at the surface in some cases traversing cuticle, possibly reaching epidermis. Plants are known a sink for atmospheric mercury (Hg), current paradigm is that uptake of gaseous elemental Hg occurs by way stomata. Four species, Rudbeckia hirta, Sorghastrum nutans, Andropogon gerardii, Populus tremuloides, were exposed air from different sources CO2...
