For most of the people specially belong to the Northern India, wheat is a very important crop because their main flooding depend upon wheat, there are several eatable food products prepared by wheat. Wheat is cultivated mostly in Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal and Madhya Pradesh. Recently in these states industrialization and infrastructural development work are going very fast causing huge amounts of pollutants and particulates entering into the atmosphere. Pollutants are mainly oxide of carbon, oxide of nitrogen, oxide of sulphur, oxide of chlorine, chloride ions, ammonia, organic acids and aldehydes whereas particulates are dust, smoke, mist and fog particulates are deposited on the surface of wheat some of these particulates are hydroscopic in nature. They absorb pollutants and form acids. These acids in turn develop micro electrochemical call with flower of wheat which destroy flowering of wheat. Other factors are acid rain; global warming and depletion of ozone layer also affect the production of wheat crops.
