There are four components to tropospheric ozone production, as a result of Man's actions.
Production reactions primarily involve hydrocarbon and nitrogen oxide gases and require sunlight.
Figure 1 shows the monthly mean simulated and observed O 3 over East Asia in June 2006. Recently, atmospheric ozone pollution has demonstrated an aggravating tendency in China. Spatial distribution of lower tropospheric O3. Ozone exposure can aggravate existing respiratory conditions such as asthma, reduce your lung function and capacity for exercise and cause chest pains and coughing.
Ozone can also be found in the troposphere, the lowest layer of the atmosphere.Tropospheric ozone (often termed "bad" ozone) is man-made, a result of air pollution from internal combustion engines and power plants.Automobile exhaust and industrial emissions release a family of nitrogen oxide gases (NOx) and volatile organic compounds (VOC), by-products of burning gasoline and coal. The Air Quality Planning Unit's primary goal is to protect your right to breathe clean air.
2. This … If you can do this at work and everywhere else you go, then you’re doing a small, but important part to reduce ground level ozone. 127 the free troposphere with fresh NOx emissions.
Young children, adults who are active outdoors and people with respiratory diseases are most susceptible to the high levels of ozone encountered during the summer. Road Transport emissions (RTE) are a significant anthropogenic global NOx source responsible for enhancing the chemical production of tropospheric ozone (O3) in the lower troposphere. Ozone also occurs naturally at the earth’s surface, due in part to transport downward from the ozone layer in the stratosphere and in part to naturally occurring chemistry in the lower atmosphere (the troposphere).
Learn Tropospheric ozone with free interactive flashcards.
Despite what a lot of people say, too much oxygen is actually bad for your body, as you need the other gasses in the air to survive.
Guided by the Clean Air Act, we work collaboratively with states, communities, and businesses to develop and implement strategies to reduce air pollution from a variety of sources that contribute to the ground-level ozone or smog problem.
Madronich, S. and Hess, P. (1994) The oxidizing capacity of the troposphere and its changes, in G. Angeletti and G. Restelli (eds. Choose a cleaner way to commute. Chemical destruction of ozone is largest in the lower 128 troposphere where water vapour concentrations are high and in hig hly polluted regions where there 129 is direct removal by reaction with NO. However, ozone during pollution events is approximately ten times the natural level. ), Physico-Chemical Behaviour of Atmospheric Pollutants, Air Pollution
Its effects on plants include impeded growth and seed production, reduced functional leaf area and accelerated ageing. Photochemical pollution is formed from emissions of nitrogen oxides (NO x, where NO x = NO + NO 2) and of volatile organic compounds (VOCs) and carbon monoxide (CO) in the presence of sunlight.Ozone (O 3), the major photochemical pollutant, is transported across national boundaries (Simpson and Malik, 1996). Tropospheric ozone is a highly reactive oxidant that significantly reduces crop productivity as well as the uptake of atmospheric carbon by vegetation. Tropospheric ozone: background information.
