The rapid growth in industries has led to considerable economic growth. However, apart from the benefits it has also contributed to the increase in pollution of land, water, air, noise resulting in degradation of the environment. Industries contribute to the following five types of pollution: (a) Air pollution: The paper factories, chemic factories, pulp. chemical, dyeing and textile industries emit out large amount of smoke. This smoke releases a high amount of undesirable gases, such as sulphur dioxide and carbon monoxide in the air which contribute to the air pollution. If there is any leakage of toxic gases it can be very hazardous with long-term effects. It can potentially affect the human health, animals, plants, buildings and the atmosphere as a whole. (b) Water pollution: Many industries including the paper industries, chemical industries and textiles industry release harsh chemical substances and other untreated wastes materials into the water resources leading to water pollution. Agriculture and fertilizer wastes when dumped in the water bodies contribute to lead and mercury poisoning in the water bodies which make the water unfit for the flora and fauna of the hydrosphere.
