(b)Pathogens(viruses,bacteria,fungi,protozoa etc)are biological pollutants of water. They cause typhoid,cholera,dysentery,jaundice,hepatitis. 2)Removal of desirable substance from water bodies: With increase in the amount of organic waste the bacteria multiply rapidly and use up the available oxygen.
(c)Recycling and Reuse of wastes: To minimize soil pollution, the wastes such as paper, plastics, metals, glasses, organics, petroleum products and industrial effluents etc should be recycled and reused. Ex: Industrial wastes should be properly treated at source. Integrated waste treatment methods should be adopted.
