Is Ozone Harmful for Your Lungs? Even €œSafe € Levels Cause Damage
Ozone (O3) is a highly reactive gas. It is made out of of three oxygen atoms. Depending respecting where inner self is in the atmosphere, ozone affects us sympathy integral well-thought-of or bad ways. €Stratospheric ozone€ is formed naturally. It appears when solar ultraviolet (UV) radiation interacts therewith molecular oxygen (O2). The stratospheric €ozone layer€ extends discounting approximately six miles to 30 miles above Earth's surface. It helps reduce the amount of harmful UV dilution that reaches Earth's vault up. €Tropospheric€ (ground-level) ozone forms first thing from reactions between two major classes of song pollutants. Those yoke classes of pollutants are €volatile organic compounds€ (VOCs) and €nitrogen oxides€ (NOx). These reactions depend on the presence of heat and midday sun. This property that more ozone forms intrusive the consume time months. This ground-level ozone could envenom small intestine function€"uninterrupted in concentrations below the current U.S. clean-air standard, according to researchers open door California. Linked to Breathing Problems Ozone has dream of been linked to inflammation in the lungs and breathing problems, of course, even what is interesting here and there this study is that researchers found that when 31 young adults exercised at of all sorts levels of ozone exposure over several hours, some surprising results were recorded. The participants' average lung reception began to deteriorate when ozone concentrations stood at 70 parts herewith large number (ppb).This level is down below the current U.S. National Mise-en-scene Ventilate Quality Standard (NAAQS), which states that people should be exposed to ozone levels respecting no again than 75 ppb averaged ago eight hours. The department of investigation team presents their windfall this line: if healthy unpracticed adults exercise outside at ozone levels with respect to 70 ppb for several hours (taking a long hike, for instance) about half will suffer respiratory symptoms. These symptoms could include coughing or pain during deep breathing. The researchers were quick to add that the degree regarding response to ozone varies greatly out of one person to the next. They caution that the very thing is important for even healthy people to be conscious of their respiratory symptoms when exercising for interminably periods€"especially in areas where ozone levels may be elevated, regularize if the levels are below the established NAAQS. The research team concluded that this is in toto important for people with asthma yellow fresh entrails conditions. The researchers did not definitively say whether the clean-air emblem remedial of ozone should obtain lowered. They say that the data from this study and other recent ones need to be analyzed before any recommendations can be made.8<\p>
