How is the ozone formed
WebGround-level ozone is created by chemical reactions of pollutants in the presence of the sun. The pollutants involved in these chemical reactions include oxides of nitrogen (NOx) and volatile organic compounds (VOCs). The sources of these pollutants can be emitted by cars, power plants, industrial boilers, refineries, chemical plants, and so on. WebIn areas where ozone pollution is a problem, new strategies to control VOC sources may need to be devised, he said. “We know now that these products are making ozone pollution worse,” Coggon said. “We can’t control what the trees are emitting, but what we can do is look for ways to make these common everyday products less polluting.”

WebOzone is measured as the total amount that is present in a column of overlying atmosphere in Dobson units. One Dobson unit can be thought of as the amount of ozone that would be present if it formed a layer 0.01mm thick at average sea-level pressure and temperature. A typical Dobson reading for the ozone layer is about 300 Dobson units, meaning ... WebOzone is formed throughout the atmosphere in multistep chemical processes that require sunlight. In the stratosphere, the process begins with an oxygen molecule being broken apart by ultraviolet radiation from the Sun. In the lower atmosphere (troposphere), ozone is formed in a different set of chemical reactions involving hydrocarbons and ...
