2. It is a carcinogenic.
3. Pyrene originates from multiple sources like combustion of petrogenic fossil fuels and incomplete incineration of municipal wastes and biomass.
Select the correct answer using the codes given below:

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: D
Notes:

Explanation: Pyrene Bioremediation:

  • Pyrene is a polycyclic aromatic hydrocarbon (PAH). It is a carcinogenic. Pyreneoriginates from multiple sources including combustion of petrogenic fossil fuels and incomplete incineration of municipal wastes and biomass. It gets lodged into the soil, water and atmosphere resulting in widespread environmental pollution.
  • Researchers at the CSIR have found a fungus named whiterot fungus Trametesmaxima IIPLC-32 which has the potential to cause microbial degradation of pyrene.
  • This fungus causes pyrene degradation using special enzymes.
  • This fungus may prove to be helpful in the remediation of pyrene and decrease the pollution level of the soil.
