Atmospheric Issues
As the planet expands, so does time periods that people spend in different interior spaces. Indoor air quality is of particular interest, since it effects behavior, ventilation, and the health of people. There is major concern for health issues resulting from indoor air pollution, as well as from the atmosphere. Similar to the Volatile organic compounds used in polluting indoor air quality, uses of similar chemicals are causing atmospheric issues as well. Compounds originate from indoor sources; a point of origin of gases or other materials which appears constantly in a ...view middle of the document...

Once it has broken down into chlorine, it then reacts with the oxygen atoms in the ozone and rips apart the molecules. Air pollution from mad-made sources such as, smog, factories, incinerators, transportation these do not replenish the stratospheric ozone. Sunlight triggers reactions between nitrogen oxides and volatile hydrocarbons (Berg, 2011)
A study conducted in central Germany with 622 homes in a midscale city called Leipzig, showed 2,242 measurements of more than 60 VOC’s in a single home. Studies concluded “items, activities, and buildings emit fixed compound spectra” (2014) Depending upon the VOC lifetime and the emission strength, the source intensity is variable, but usually the composition is relatively constant. Therefore, one must consider mixtures of VOC’s from multiple sources, because various source combinations of numerous air pollutants, including interactions as well as superposition of compounds, possess different effects on human health and the universes atmosphere. Studies aimed at finding characteristic sources of VOC’s in urban housings in areas without strong outdoor influences.
Air pollutants combined with global warming would be carbon dioxide, coal, oil, methane, nitrous oxide and the tropospheric ozone. Chemicals like toluene/benzene are good markers for influencing outdoor air and traffic. “Local conditions like industry and busy roads create emission sources that differentiate the pollution amount of homes in industrial, urban, and nonurban regions. A high variety of possible sources of indoor and ambient air poses a big challenge for scientists to assign different compounds to their point of origin” (2014).
Several aspects label atmosphere issues, from car exhaust to cigarette smoking all of these issues pollute air and effect the environment as well as our health. Air pollutants have a lasting effect on this world and the people who live here. Through science and technology, it is possible to identify pollutants impacting air people breathe in and atmospheric dangers protecting our world.
An outdoor atmosphere such as car exhaust pollutes the earth’s atmosphere. Car exhaust causes pollution from carbon dioxide released when vehicles burn fuel. This is a major issue for our environment in urbanized areas. The area with millions of vehicles driven daily produces massive amounts of air pollutants into congested areas. With urbanization comes expansion when this happens cities build roads, buildings, and homes to accommodate the population. The large...
