Which organism is used as indicator of fecal pollution in water

Which organism is used as indicator of fecal pollution in water Correct Answer E. coli

E. coli is used as an indicator of fecal pollution in water.

Key Points

  • Fecal contamination is the contamination of water with disease-causing organisms (pathogens) that may inhabit the gastrointestinal tract of mammals.
  • Infectious diseases such as cholera and other diarrheal diseases, dysenteries, and enteric fevers occur as a result of fecal contamination.

Important Points

  • Indicator organisms are used to assess overall sanitation or environmental conditions that may signal or indicate the potential presence of pathogens of food safety concern.

Additional Information

  • Clostridium:
    • C. perfringens as a conservative water quality indicator for total fecal pollution monitoring is no longer justified but suggest It can be used as a tracer for excreta from nonherbivorous wildlife and human sewage.
  • Bacillus subtilis:
    • It is used as an "indicator organism" during gas sterilization procedures, to ensure a sterilization cycle has been completed successfully.
  • Salmonella:
    • This organism is also present in fecally contaminated water. But, this is not preferred as an indicator organism.

Read the paragraph and answer the question that follows: Incessant combustion of fossil fuels emits toxic gases, polluting the air; urbanization results in deforestation and hence poor air quality; littering of plastic waste damages the productivity of soil and pollutes water bodies. Environmental pollution results in more serious consequences like – global warming, unexpected climatic changes, depletion of natural resources, species depletion, and various other adverse effects leading to a lowered sustainability of life on earth. Another prime contributor to the pollution of the environment is plastic pollution. Plastic bags those are not disposed of properly, reach the soil and water bodies, polluting them and damaging dependent lives. Being non-bio degradable plastic lingers around for years, rendering them useless. What is the prime contributor to pollution?

In this question, a passage and a statement related to it have been given. Read carefully the verse and review the statement based on it. Delhi, which is one of India's capital an d one of the largest cities in the world, is undergoing severe crisis, due to its high level of urbanization, increasing population and high levels of pollution. Studies have proven that Are the biggest factors of pollution used for industrial and domestic use? And due to their use, people here emit large quantities of nitrogen oxides (NOx), ozone (O3), black carbon (BC) and microorganisms (PM). According to the 2015 Global Burden of Disease report, there were 1.09 million deaths due to PM 2.5 in India. Air pollution was included as one of the 10 biggest threats to health. According to the World Health Organization, 37 cities of India are among 100 worst polluted cities in the world, where PM10 was found to be the highest ever. For the production of ozone, together with sunlight and heat, nitrogen oxides (NOx) and organic compounds (VOCs) are needed simultaneously. Therefore, in the summer months, ozone is produced in large quantities in the cities. Statement: Air pollution is one of the top 10 factors affecting health in India. Select the most suitable from the following options A-statement is absolutely true B-statement is probably true C-statement can not be reviewed D-statement is completely false
