Study the picture given below and answer the following question: State one measure to control this pollution.

The contamination of water bodies usually caused due to human activities is called water pollution. The causes of water pollution are domestic waste, industrial effluents, urbanization, fertilizers. The steps to prevent water pollution are as follows: Trees or plants should be planted along the banks of rivers. Pollutants from industries should not be discharged into the water bodies.

Study the picture given below and answer the following question: Name one pollutant that causes the above pollution.

The contamination of water bodies usually caused due to human activities is called water pollution. The causes of water pollution are domestic waste, industrial effluents, insecticides, pesticides and detergents, fertilizers. As these pollutants get mixed with the water the aquatic animals will not get sufficient oxygen gas for respiration which ultimately leads to the death of aquatic animals.

Study the picture given below and answer the following question: Identify the type of pollution.

The contamination of water bodies usually caused due to human activities is called water pollution. The type of pollution shown in the given image is water pollution. The causes of water pollution are domestic waste, industrial effluents, insecticides, pesticides and detergents, fertilizers. As these pollutants get mixed with the water the aquatic animals will not get sufficient oxygen gas for respiration which ultimately leads to the death of aquatic animals.

Study the picture given below and answer the following question: What is a ‘Pollutant’? Explain the term.

A pollutant can be defined as a substance introduced into the environment that has adverse effects. The causes of pollution are domestic waste, industrial effluents, insecticides, pesticides and detergents, fertilizers. There are different types of pollutants: Water Pollutants, Air Pollutants, Soil Pollutants, Noise Pollutants. All living organisms and ecosystem gets affected due to pollutants. They increase the earth’s temperature that causes global warming.

Study the picture given below and answer the following question: Mention the impact of this pollution on human health.

The contamination of water bodies usually caused due to human activities is called water pollution. The causes of water pollution are domestic waste, industrial effluents, insecticides, pesticides and detergents, fertilizers. As these pollutants get mixed with the water the aquatic animals will not get sufficient oxygen gas for respiration which ultimately leads to the death of aquatic animals. In humans, consuming contaminated or polluted water causes typhoid, cholera, hepatitis and various other diseases.

This is a process in which dirt and other floating particles get stuck together to form scum which floats over the water surface. This method is used in wastewater treatment to remove the suspended light impurities.
