Since 1900, the amount of ozone near the Earth's surface has more than doubled due to more automobiles and industry.When ozone pollution reaches high levels, pollution alerts are issued urging people with respiratory problems to take extra precautions or to remain indoors. The chlorine can then enter another reaction with ozone and cause additional ozone depletion. Ozone is a gas composed of three atoms of oxygen (O3).

it is a secondary polutant because it is not dangerous until exposed to the suns rays. After working with the states and tribes and considering the information from air quality monitors, EPA "designates" an area as attainment or nonattainment with national ambient air quality standards. It extends from the ground up to a variable height of approximately 14 kilometers above sea level. Stratospheric Ozone synonyms, Stratospheric Ozone pronunciation, Stratospheric Ozone translation, English dictionary definition of Stratospheric Ozone.

Nearly 100 major cities in the United States are periodically exposed to concentrations of ozone that exceed health-based air-quality standards. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Start studying APES Ch. It can worsen heart disease, bronchitis, and emphysema.Rubber, textile dyes, fibers, and certain paints may be weakened or damaged by exposure to ozone.

This beneficial ozone has been partially destroyed by manmade chemic… But neither of these sources contributes enough ozone to be considered a threat to the health of humans or the environment.

Tropospheric ozone is formed by the interaction of sunlight, particularly ultraviolet light, with hydrocarbons and nitrogen oxides, which are emitted by automobile tailpipes and smokestacks.

It can impair an athlete's performance, create more frequent attacks for individuals with asthma, cause eye irritation, chest pain, coughing, nausea, headaches and chest congestion. Oh no! These standards apply to the concentration of a pollutant in outdoor air. The troposphere is the lowest layer of the Earth's atmosphere. Ozone (O3) is a trace gas of the troposphere, with an average concentration of 20–30 parts per billion by volume (ppbv), with close to 100 ppbv in polluted areas. Tropospheric ozone. -Tropospheric ozone is a secondary pollutant contains smog ozone- toxic to humans, animals, and vegetation. Some elastic materials can become brittle and crack, while paints and fabric dyes may fade more quickly.What can we do to decrease the production of ozone in the © 2014 UCAR with portions adapted from Windows to the Universe (© 2005 NESTA) Ozone produc-tion reactions primarily involve hydrocarbon and nitrogen oxide gases, as well as ozone itself, and all require sunlight for completion. Tropospheric ozone exposure is responsible for an estimated one million premature deaths each year. Tropospheric ozone, commonly known as smog, is formed when VOC and nitrogen oxides (NO X) react in the atmosphere in the presence of sunlight. What are the advantages and problems with the substitutes for CFCs?-Substitutes for CFCS, Collection and Reuse of CFCs, Montreal Protocol-A 1987 treaty of 180 nations agreed to cut CFC production in half. EPA calls these “criteria air pollutants” because their levels in outdoor air need to be limited based on health criteria.There are national ambient air quality standards (NAAQS) for each of the criteria pollutants. Ozone (/ ˈ oʊ z oʊ n /), or trioxygen, is an inorganic molecule with the chemical formula O 3.It is a pale blue gas with a distinctively pungent smell. Ozone in the air we breathe can harm our health, especially on hot sunny days when ozone can reach unhealthy levels. Many urban and suburban areas throughout the United States have high levels of "bad" ozone. Plants and soil release some. Even relatively low levels of ozone can cause health effects. Ozone pollution is a concern during the summer months because strong sunlight and hot weather result in harmful ozone concentrations in the air we breathe. Ozone is a gas composed of three atoms of oxygen (O3).

Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Near Earth’s surface, ozone is produced by chemical reactions involving naturally occur-ring gases and gases from pollution sources. This series of reactions is what is known as a catalytic chain reaction.-Spring season (October) of Antarctic, ozone is at its thinnestExplain the role of the following in the formation of the Antarctic Ozone Hole:-Polar vortex: during the polar winter, the Antarctic air mass is isolated from the rest of the atmosphere and circulates about the pole in what is known as the polar vortex. Ozone is least concentrated in th… The good news is, this hole is diminishing. Tropospheric Ozone Definition stratospheric ozone is good for humans but tropospheric is not, it is produced by smog and lies in the tropospheric zone.
