Garden Grove, CA, May 1st, 2014
This week is Air Quality Awareness Week and the U.S. Environmental Protection Agency (EPA) has posted special information about air quality and its impact on people’s health in recognition of the occasion. There are many components to air quality, but one that is known especially well to residents of California is ozone.
Ozone is a significant component to the creation of smog, a type of air pollution that frequently causes issues in many parts of California. Both ozone and smog are health concerns for not only people spending time outdoors, but also for people indoors as it infiltrates into homes, schools and businesses.
Ozone is found in two regions of the Earth's atmosphere, at ground level and in the upper regions of the atmosphere. Both types of ozone have the same chemical composition and while upper atmospheric ozone protects the earth from the sun's harmful rays, ground level ozone is the main component of smog and can cause health concerns.
Ground level ozone is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOCs). It is likely to reach unhealthy levels on hot sunny days in urban environments, but has also been observed during cold months in some high elevation areas in the Western United States. Ozone can also be transported long distances by wind so even rural areas can experience high ozone levels.
“Even relatively low levels of ozone can cause health issues for some people,” said Michael Chapman, Laboratory Manager at LA Testing’s Garden Grove facility. “Those with lung disease, children, older adults and people who are active outdoors may be particularly sensitive to ozone. LA Testing’s network of laboratories provides analytical services and sampling supplies for ozone and a wide range of other chemical and microbial contaminants to help protect people’s health.”
LA Testing recently sponsored an online video about ground level ozone and health risks that can be seen at: http://youtu.be/idvxQsd_yRM.
