Chemical and paper factories, brick kilns, refineries, and smelting plants are major contributors of air pollution. Industries processing paper, pulp, chemical, textile and dyeing, petroleum refineries, tanneries, and electroplating industries let out untreated pollutants into the water bodies causing water pollution. Many industries release hot water from factories and thermal power plants directly into the rivers and ponds resulting in Thermal pollution. Factory equipment, generators and electric drills are also major contributors to noise pollution. Radioactive wastes from nuclear power plants, nuclear weapon production facilities cause cancers, birth defects and miscarriages.
