• Abstract

  The concentration of ozone (O3) has increased worldwide threatening species and ecosystems. Plants act as O3 sinks via stomatal and non stomatal processes. Non stomatal processes include the removal of O3 molecules of the boundary layer that cover the leaf by volatile organic compounds (VOC) emitted by plants. Many studies have attempted to the development of critical levels of vegetation…

• Abstract

  The concentrations of ozone (O3) have increased annually in both urban and rural areas, which can result in reduced agricultural productivity and damage to plant species, communities and ecosystems. It is necessary to know the O3-induced effects on plants to determine the concentration threshold that should not be overcome to ensure the protection of species and vegetation. In Brazil ther…
