Environmental Pollution

Which of the following are the reasons/factors for exposure to benzene pollution?

  1. Automobile exhaust
  2. Tobacco smoke
  3. Wood burning
  4. Using varnished wooden furniture
  5. Using products made of polyurethane Select the correct answer using the code given below:

B.2 and 4 only
C.1, 3 and 4 only
D.1, 2, 3, 4 and 5
A.1, 2 and 3 only

Correct Answer: Option D

Benzene is a volatile organic compound (VOC) with significant health implications, including cancer and aplastic anemia. Exposure primarily occurs through inhalation.

Here's a breakdown of how each factor contributes to benzene pollution:

  • Automobile Exhaust: Exhaust is a major source of benzene in the environment due to the presence of benzene in gasoline.

  • Tobacco Smoke: Both active and passive smoking are significant sources of benzene exposure.

  • Wood Burning: Incomplete combustion during wood burning releases benzene.

  • Using Varnished Wooden Furniture: Some varnishes and wood finishes contain solvents, including benzene, that can be emitted over time.

  • Using products made of Polyurethane: Burning polyurethane foams can release benzene, along with other toxic gases.

Therefore, all the given options are sources of Benzene Pollution.

Hence, option D is correct.
