Question

The use of unleaded petrol and compressed natural gas in automobiles reduces noise pollution

• A. True
• B. False

Answer 1

Answer: (B)

Cars using leaded petrol have higher emissions of highly dangerous particulate pollutants due to lead content in fuel. Long-term exposure to low levels of lead can affect mental development in children. The higher the average blood lead concentration in a population, the lower is their average IQ.

CNG burns cleaner when compared to petroleum products. Carbon monoxide emissions are reduced by roughly 80 percent, and 44 percent fewer hydrocarbons are produced in comparison to petroleum fuels. So the use of unleaded petrol and compressed natural gas in automobiles reduce air pollution.
