Most of the pesticides are applied through spraying in the fields, speech on effects of pollution. This spraying increases the quantity of many chemicals used in pesticides in the surrounding atmosphere and hence pollutes the environment.
Air pollution is mainly the outcome of the dust generated during mining and processing activities. During mining, dust arises from blasting excavation, crushing and transportation of ore, and from tips, stockpiles and de watered tailing. Huge quantities of dust become wind borne. The power stations that use the combustion of coal or petroleum for the generation of heat and power produce smoke and sulphur speech on effects of pollution SO 2.
It has been estimated that thermal power stations emit about two-thirds of total sulphur dioxide released in air. These gases result in air pollution. There are many other sources which cause small amounts of air pollution. These include cigarette smoking, burning of heaps of solid wastes, air conditioning appliances, diesel generation sets, and construction activities etc.
Pollution of air differs in some aspects from pollution of waste. Discharges from industrial premises in the atmospheres are often more or less continuous during working hours and they can drift high or low and in any direction, depending on the wind and weather.

Air pollution can affect plants to changing degrees, depending upon the level of air pollution. It causes injury to sensitive plants, speech on effects of pollution. Suspended particulates after deposition on leaves affect the photosynthetic activity. Several chemicals such as insecticides, herbicides, fungicides and pesticides used widely in agriculture are known to produce foliar lesions, chlorosis and abscission of leaves and reduction in fruit set.
Several other types of particles in air such as coal dust and asbestos have been linked with necrotic lesions, reduction in fruit set in plants, silicosis and lung cancer respectively. Emissions into the air that are intended to cause changes in the weather, such as local rainfall, and others that are suspected of causing permanent atmospheric changes are of special nature.
Quite recently concern has been expressed over the fate of the ozone layer enclosing the earth and the possible effects on climate.
Atmospheric particulate due to fuel combustion for industrial and household heating purposes can scatter and absorb sunlight and hence reduce visibility. The effect of particulate matter includes corrosion of metals, erosion and soiling of buildings, sculptures, etc. Air pollution is caused both by economic development and poverty.

Moreover, many underdeveloped countries are promoting fossil fuel energy policies and practices that are environmentally unsustainable and cause environmental degradation at the local particulates and smog and regional acid deposition levels. There are about two billion people without access to electricity, usually using traditional fuels with poor ventilation for cooking, leading to a high incidence of respiratory infections, diseases and deaths in women and children.
Air pollution is caused by industrial and agricultural development, establishment of thermal speech on effects of pollution plants and development of mining sector in underdeveloped countries of the world.
Thus air pollution is a serious problem in cities and urban manufacturing areas in both underdeveloped countries. There is particulate matter in the form of dirt, dust and solid waste thrown in the air that is harmful for humans, animals and plants.
