Common theory questions

Which exhaust emissions contribute to the formation of ground-level ozone?

The emissions of hydrocarbon and nitrogen oxide contribute to the formation of ground-level ozone.

Ozone in the atmosphere protects against the sun's radiation, but when it is formed too close to the ground it is harmful to humans and the environment.

Ground-level ozone irritates our mucous membranes and lungs, prevents photosynthesis and damages the water balance of plants.
