Air pollutants and greenhouse gases have common sources and are diffused all over the world, affecting ecosystems. During recent years, an increase in the air pollutant precursor for photochemical reactions has increased the effects of air pollution stress in the troposphere on plants. Especially in developing countries, where the current ambient air pollutant concentrations are high, due to rapid urbanization and an increase in fossil fuel consumption over the past decades, this increase could be harmful to plant growth and human health in urban ecosystems.
The impacts of air pollution on the physiological, morphological, and biochemical properties of plants have been investigated in several studies. Air pollutants generally enter leaves through the stomata and have negative impacts on the growth of plants, leading to a reduction in plant productivity .
Visible injury to leaves can take the form of white stippling, necrotic tip burn, and tiny purple, yellow, brown, or black spots. These symptoms are indicative of a loss of vitality in the vegetation. The production of reactive oxygen species (ROS) as a result of air pollution concentrations in plants reduces the growth of plants by severely compromising the integrity of metabolically important membranes. ROS from air pollution can also be combined with signaling pathways, which affects the response of plants to oxygen stresses and can even cause programmed cell death. These physiological disorders by long-term air pollutant exposure can result in lower quality in crops, due to a restriction of carbon storage. In addition, airborne pollens which originate from urban vegetation and particular matters produced by industrial areas are widespread during the growing season. The density of air pollutants such as ozone, CO2, NOx, SO2, airborne pollens and particular matters is highly correlated with the prevalence of allergies .
This Special Issue includes topics on the combined and interactive effects of air pollution and climate change on vegetation and ecosystems, the discrimination of species-specific physiological behavior in relation to air pollution, the impacts of elevated CO2 and nitrogen deposition on several forests, photosynthetic responses to elevated air pollutants, and air pollution-induced effects on the forests of several countries. There is evidence that effects of air pollutants on urban forests can be seen as a multi-pollutant, multi-effect problem for urban forest ecosystems. The combined effects may significantly differ from a sum of separate effects. Plants ecologists, physiologists, physicists, meteorologists, environmentalists, and any other researchers are welcome to submit papers.
