Abstract

This review provides knowledge about air pollution and its impact on agriculture crop yield and
quality in developing countries. The need of increasing agriculture production has been very
important for the increasing of population. Air pollutants pose risks on yield of crops depending on
the emission pattern, atmospheric transport and leaf uptake and on the plant’s biochemical defence
capacity. In the recent research it is identified that the agriculture production is being affected by
air pollution, the impact of air pollution is caused by number of air pollutants (sulphur dioxide
(SO2), Nitrogen oxides (NOx), and Ozone (O3). Air pollutants produce reactive oxygen species
(ROS), which adversely affect biochemical processes of plants and reduce their tolerance capacity
to other stresses also. Several vital physiological processes such as photosynthetic CO2 fixation and
energy metabolism are also affected negatively by air pollutants. An adverse effect caused by air
pollutants depends not only upon its concentration, but also on the duration and combination of air
pollutants. Ozone is the most phytotoxic of the common air pollutants. It is concluded that the
continuous increasing concentration of pollutants will pose a critical threat to future world food
security.
