Escherichia coli is used as an indicator organism to determine pollution of water with:
Updated On: Jun 23, 2024
Heavy metals
Faecal matter
Industrial effluents
Pollen of aquatic plants
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
E. coli is commonly found in the intestines of warm-blooded animals, including humans, and is often used as an indicator of fecal contamination in water. The presence of E. coli in water indicates the potential presence of fecal matter and the possible presence of harmful pathogens associated with fecal contamination. It is an important marker for assessing water quality and safety.
So, the correct option is (B): Faecal matter
So, the correct option is (B): Faecal matter

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Concepts Used:
Water Pollution
- Water pollution means the contamination of water bodies such as seas, lakes, rivers, aquifers, oceans, and groundwater caused majorly due to inhuman activities with industrial and agricultural effluents. It is the change of chemical, biological, or physical properties of water that will result in a destructive consequence for living organisms.
- Portable water is considered safe for human and animal consumption as well as used for drinking, cooking, crop irrigation, washing, etc,. Nowadays, chemicals, bacteria, and other pollutants are also influencing this. It adversely acts on all the living forms, directly or indirectly depending upon the source. The effects of water pollution can be felt for years to come.
Sources of Water Pollution:
The following are the major sources of Water Pollution:
- Domestic Waste
- Urbanization
- Deforestation
- Industrial effluents
- Social and Religious Practices
- Insecticides and pesticides
- Detergents and Fertilizers
