Environmental pollution can be defined as “the unfavorable alteration of our surroundings”
3.1.1 Types of pollutants 1.
1. Bio degradable pollutants – decompose rapidly by natural processes. 2. Non- degradable pollutants – do not decompose or slowly decompose in the environment. 3.1.2 Classification of Pollution Air pollution Water pollution Soil pollution Marine pollution Noise pollution Thermal pollution and Nuclear hazards 3.2 AIR POLLUTION The presence of one or more contaminants like dust, smoke, mist and odor in the atmosphere which are injurious to human beings,

3.1.2 Classification of Pollution Air pollution Water pollution Soil pollution Marine pollution Noise pollution Thermal pollution and Nuclear hazards
3.2 AIR POLLUTION The presence of one or more contaminants like dust, smoke, mist and odor in the atmosphere which are injurious to human beings, plants and animals.
3.2.1 Sources of air pollution Natural pollution – volcanic eruptions, forest fires, biological decay. Man – made activities – Thermal power plants, agricultural activities.
3.2.2 Classification Primary pollutant – these are those emitted directly in the atmosphere in harmful form like CO, NO. Secondary pollutant – these may react with one another or with the basic components of air to form new pollutants.
3.2.3 Control Measures 1. Source control Use only unleaded petrol Use petroleum products and other fuels that have low sulphur and ash content Plant trees along busy streets because they remove particulates and carbon monoxide and absorb noise.
