उत्तर
Replacement of coal by the oil fuel has increased the problem of pollution. The presence of oil in a water course is undesirable since it creates aesthetic problems. It has a tendency to spread over the surface of water; diffusion of oxygen into water is inhibited and re-aeration of water is affected.
