Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere. How is ozone produced and what is its function? StratosphericRead More →
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. What breaks CFCs apart in the stratosphere? The UV light in the stratosphere breaks up the CFCs. They release chlorine, and these free chlorine atomsRead More →
1. In the area to be tested for the presence of ozone, spray a strip of the test filter paper with distilled water and hang it at a data collection site out of direct sun light. Make certain the strip can hang freely. [Note: The xerographic process in most copyRead More →
Certain industrial processes and consumer products result in the emission of “halogen source gases” to the atmosphere. These gases bring chlorine and bromine to the stratosphere, which cause depletion of the ozone layer. Which CFC element causes ozone depletion? Photodissociation of the chlorofluoromethanes in the stratosphere produces significant amounts ofRead More →
When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. What causes ozone smell in house? 3. ElectricalRead More →
CFCs do not easily react with other substances. In fact, they break up only through sunlight, which divides their molecules, causing the release of chlorine (Cl). Once the chlorine is released, it is able to react with ozone (O3), to form chlorine monoxide (ClO) and oxygen (O2). Why are CFCsRead More →
