ABSTRACT
Air pollution is a huge environmental problem on a global scale because it has a considerable impact on plant development and productivity. Pollutants that harm plant tissues, lower photosynthetic rates, and hinder nutrient uptake, such as ozone O3, sulfur dioxide SO2, nitrogen oxides NOx, and particulate matter PM, can result in reduced growth and production. For example, oxidative stress brought on by ozone damages plant cells, lowers chlorophyll levels, and stunts growth. While sulfur and nitrogen compounds change the pH and nutritional availability of the soil, so impairing plant health, particulate matter can block sunlight, lowering photosynthetic efficiency. Plant species, pollutant type, concentration, and length of exposure all affect these impacts differently. The mechanisms by which air pollutants impact plant physiology are examined in this paper, along with the productivity losses that ensue and possible mitigation and adaptation measures.
