An Ozone Action Day, which can be declared by a local municipality, county or state, is observed at certain times during the summer months, when weather conditions (such as heat, humidity, and air stagnation) run the risk of causing health problems.he ozone layer protects people from the sun's most damaging ultraviolet rays. Because the ozone layer is located high in the atmosphere, people are not directly exposed to it. Ground-level ozone, however, is a health hazard because people breathe it.
Ozone is a colorless gas. Chemically, ozone is very active; it reacts readily with a great many other substances. Near the Earthâs surface, those reactions cause rubber to crack, hurt plant life, and damage peopleâs lung tissues.But ozone also absorbs harmful components of sunlight, known as âultraviolet Bâ, or âUV-Bâ.his depleted region is known as the âozone holeâ. The area of the ozone hole is determined from a map of total column ozone. It is calculated from the area on the Earth that is enclosed by a line with a constant value of 220 Dobson Units.
