Air pollution is a matter of great concern in the globe. Generally air pollutant generates from industries, automobiles, etc. and the primary pollutants may easily convert to secondary pollutants. Both of these pose serious threat to the plant community viz. crops, vegetables and avenue plant species are depending on the emission pattern, atmospheric transport and leaf uptake and on the plant’s biochemical defense capacity. An impact caused by air pollutants depends not only upon its concentration, but also on the duration (acute and chronic exposure) and combination of air pollutants. Biomonitoring on plant species is an easy tool to know bioindicator species in which exposure of air pollutants can easily be identified. The present review deals with past and present research works of major gaseous pollutants emissions and their impact on crop, vegetables and tree species performance from available literatures.
