Effects of Pollution on Waterbodies
Effects of Pollution on Waterbodies
The polluted water affects mankind as well as plants and animals.
1. Many diseases like cholera, dysentery, measles, typhoid etc. are caused due to consumption of polluted water.
2. The polluted water enhances the growth of algae and water hyacinth which reduces the supply of oxygen and sunlight to the aquatic fauna and flora resulting in adverse effect on their growth. This is called Eutrophication.
3. Industrial water contains compounds of mercury, cadmium, lead, arsenic, chromium etc. which are highly poisonous. They cause serious disorders of many kinds. They may cause death.
4. Flourides in water cause fluorosis which affect teeth and bones.
Soil Contamination: Soil becomes infertile due to the deposition of harmful chemicals discharged by industries. The high concentration of poisonous chemicals in soil can cause serious diseases in future generations.
Oil Spills from pipeline and tankers at sea are one of the most dangerous forms of pollution. The oil spreads very fast on the surface of water. It cuts off the supply of oxygen to the organisms living in sea and cause their death.
Soil Erosion caused by rains and floods takes all the sediment to the rivers and lakes. This results in the death of organisms living at the bottom of the lake or river thus upsetting the balance. The Dal lake in Srinagar, Nainital lake in Uttarakhand and Ulsoor lake in Bangalore are examples where silting is causing the choking of the lakes.
