Question : 4
Total: 6
Explain five types of 'industrial pollution.'
Solution:  
Industrial pollution creates environmental degradation in the following ways :
Due to the release of undesirable gases like sulphur dioxide and carbon monoxide, air borne particulate matter containing smoke, dust and spray mist, toxic gases by burning fossil fuels in the industries, air pollution is caused. Release of these pollutants also causes acid rain. Thus, chemicals pollute the atmosphere and cause life threatening diseases. This also affects monuments, buildings and animals.
Water pollution is caused by organic and inorganic industrial wastes discharged into the rivers, liquid wastes produced by chemical and textile industry, tanneries, petroleum refineries, electroplating industries and metallic pesticides etc. solid wastes like fly ash, phospo-gypsum and slags produced by iron and steel industries. Water pollution leads to loss of rich aquatic life and flora-fauna. This causes water scarcity as well. This also causes diseases like typhoid and cholera.
All the pollutants that cause water pollution, along with wastes from nuclear power plants are responsible for land pollution. Water and land pollution are closely related. All the liquid and solid affluents, if not being disposed off into the rivers, goes directly into the soil and degrade the land areas.
All the unwanted sounds caused due to industrial and construction activities, machinery, generators and drilling activities create irritants and are a source of stress.
