Ozone Pollution
What is Ozone?
Ozone is a mixture of multiple molecules in the atmosphere that shields the planet from harmful UV rays, this is referred to as the "Good Ozone" but when ozone is produced closer to the ground it is a harmful gas for humans to breath in; this is known as "Bad Ozone".
What causes Ozone pollution?
The good and naturally produced ozone layer in the stratosphere is being destroyed by the man made Ozone-Depleting Substances(ODS). These ODS's are usually found in coolants, fire extinguishers, aerosol cans and pesticides. Overuse of these products is causing holes in the ozone layer and allowing more and more harmful UV rays into the atmosphere.
Along with the depletion of the "good" ozone in the atmosphere the "bad" atmosphere is also continuing to grow. Emissions from industrial facilities and electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents are some of the major sources of NOx and VOC, which are the harmful chemicals that make up the "bad" ozone.
What are some threats that Ozone pollution presents?
When the ozone layer in the upper atmosphere begins to have holes due to ozone pollution it allows for harmful UV rays to enter the atmosphere. These rays when exposed to can cause various forms of skin cancer and immune system disorders. When exposed to the ozone close to the earths surface conditions such as chest pain, coughing, irritation, asthma and permanent lung damage.
What is being done to help this issue and what you can do.
In 1987 the United States along with over 180 nations adopted the Montreal Protocol which calls to phase out the production and use of Ozone Depleting Substances. With this solution the ozone is currently on track to be repaired by 2050 if the United States is able to follow through with this protocol. The EPA has also passed the Clean Air Act which sets standards on all the air we breath. Programs are set to reformulate gas and cut down emissions to cleanse the air.
