Effect of traffic flow on the release of pollutant gasesFeatured science projectScience project video

Conclusion

The hypothesis that pollution will be highest during the peak hours in the early morning and late evening, due to high traffic, has been proven to be true.

Pollutant gases released from fuel combustion in motor vehicle engines has significant effects on our environment. They also negatively affect the health of humans and animals. Many regulations have been introduced to regulate vehicle emissions. The use of hybrid vehicles fitted with electric enginse help to reduce gasoline consumption and lessen the emission of pollutant gases.

Also consider

The science fair project may be repeated with diesel-operated vehicles, like busses and trucks, to test for differences in the levels of pollutants emitted.

The experiment may also be repeated in other areas, like more urban or residential areas, to test for differences in the levels of pollutants emitted.
