Levels of carbon monoxide emission by aging carsFeatured science projectScience project video

Observation

The results show that the 20-year-old car has the highest carbon monoxide emission levels while the new car produces the least carbon monoxide. The carbon monoxide levels were higher in the closed garage and lower in the open space.

 

Test location Age of car and carbon monoxide emission measured in parts per million (ppm)
  New 5 years 10 years 20 years
Closed garage 18 21 112 337
Open space 6 9 38 146
