But water pollution is concentrated within a few sub-sections, mainly in the form of toxic wastes and organic pollutants. Most of these defaulting industries are leather, pulp and paper, textiles, chemicals, sugar mills, distilleries, and thermal power stations. Not all industries have treatment facilities for industrial effluents. As small-scale industries cannot afford enormous investments in pollution control equipment as their profit margin is very slender.
9. Noise pollution refers to a noise that causes a condition which is unbearable and uncomfortable for human beings. After technological innovations, it has become a serious problem, especially in urban areas. The noise can be from various sources such as:
   1. Factories, mechanised construction and demolition works, aircrafts automobiles loudspeaker, siren, etc.
   2. The noise produced by traffic is a major source of noise pollution. It creates a huge inconvenience for the people. Intensity and nature of noise made by traffic is dependent on various factors such as type of vehicle, (aircraft, train, etc) condition of road and condition of the vehicle (in case of automobiles).
   3. In sea traffic, noise pollution is limited to the harbour because of the loading and unloading activities of containers.
