Ozone Monitoring & Testing
The ozone layer in our atmosphere is a critical part of good health, without it the earth would be exposed to 10% more harmful UV radiation.
Ozone monitoring and testing can be done by Environmental Monitors.
Environmental Monitors are an important aspect of any ozone monitoring program. We provide the data that is used to identify potential problems in the ozone layer or other aspects of our environment.
Our devices are usually placed in high altitude sites, which makes it easier for them to collect accurate readings on atmospheric composition and meteorology.
What is the ozone layer
The ozone layer in our atmosphere is a fragile shield that protects us from ultraviolet radiation coming from the sun. It filters out much of this harmful UV radiation from reaching the Earth’s surface, making it a critical part of good health.
With the introduction of man-made chemicals into our environment, however, this thin shield is being depleted by up to 10% each year!

What to do if you suspect someone has been exposed to carbon monoxide poisoning?
Testing the ozone layer’s levels is done using a Dobson Unit or DU. The higher the DU reading, the more UV radiation that has passed through the earth’s atmosphere. These units are used to measure how much of this radiation is currently present in your area.
What should be monitored?
As we continue to deplete our ozone layer, it is important to test for any changes in its levels. Three areas of interest should be monitored: UV radiation levels, the amount of chlorine and bromine present, and the size and depth of the ozone hole (if applicable). The following ozone monitoring equipment will be used to test each aspect:
Monitoring UV radiation levels
UV radiation is measured with a spectrophotometer, which will detect any changes in wavelengths. These units are able to measure both UVA and UVB. They also have a built-in filter that measures the UV index of your area. Additional filters are also available that can measure longer wavelengths, allowing for specific measurements in different ranges (such as UVC or UVA).
Monitoring chlorine and bromine levels
Both chlorine and bromine are measured in a similar way, using an iodide-starch test. A solution is prepared that contains iodine, potassium iodide, and starch. This solution is then exposed to the air in your area for 10 minutes. If there are high levels of chlorine present, it will react with the starch in the test tube, changing its colour. Bromine reacts in a similar manner, but the solution turns a dark-purple colour.

Environmental Monitors provide data on atmospheric composition and meteorology at high altitude sites which makes it easier for them to collect accurate readings on things like ozone levels.
