Common theory questions

What is ground-level ozone?

Ozone in the atmosphere protects against the sun's radiation, but when it is formed too close to the ground – due to, among other things, hydrocarbon and nitrogen oxide emissions – 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.
