What is smog? Is ozone the culprit? Ozone is three oxygen molecules that near earth is created when man made pollutants and heat from sunlight are present. Ozone is not the culprit however. Hydrocarbons Billiga Nike Air Max 2019 , VOC's, and nitrous oxides (exhaust basically) are the true causes of smog. Here is what the EPA has said in the past about cars, ozone, and smog:


?Ozone is not emitted directly but is formed in the atmosphere through a complex set of chemical reactions involving hydrocarbons Billiga Nike Air Max DLX , oxides of nitrogen, and sunlight. The rate at which the reactions proceed is related to both temperature and intensity of the sunlight. Because of this, problematic ozone levels occur most frequently on hot summer afternoons. Hydrocarbons and nitrogen oxides come from a great variety of industrial and combustion processes. In typical urban areas, at least half of those pollutants come from cars Billiga Nike Air Max 180 , buses, trucks, and off-highway mobile sources such as construction vehicles and boats. In fact, a major portion of ozone-forming hydrocarbons can be attributed to a relatively small number of super-dirty cars whose emission control systems are not working properly.?


One must ask themselves why ozone is called "problematic" and not hydrocarbons Billiga Nike Air Max 96 , VOC's, and nitrous oxides? Ozone is a clear gas. Smog is a dirty, brown, fog-like substance similar to vehicle exhaust. Can it be that ozone is being made the scapegoat here to distract attention away from the heavy polluters? What is problematic is the fact somewhere around two thirds of big rigs and buses nationwide are exempt from emission controls. If one wants to point a finger at the true cause of smog that would be a great place to start. If you've ever found yourself behind an older bus at a traffic light and have seen the large Billiga Nike Air Max 270 , billowing dark clouds of exhaust that fill the air when the light turns green, you know exactly what smog looks and smells like.


Another serious health issue is the lack of emission control devices on older school buses that leak exhaust into the cabin. Here is what the Natural Resource Defense Council has to say on this subject:


" How much diesel exhaust gets into school buses?


To help answer this question, researchers from NRDC, the Coalition for Clean Air and the University of California at Berkeley measured air quality inside typical school buses as they traveled along real elementary-school bus routes in the Los Angeles area. They took continuous measurements inside the buses Billiga Nike Air Max 2018 , and compared these to air quality both just outside the buses and in passenger cars traveling ahead of the buses tested. They took readings while idling with the motor running, while traveling up and down hills or driving slowly, and while making frequent stops. And most of the buses tested did not emit a significant amount of visible black smoke. In other words, the tests re-created real-life conditions.


The results were alarming. Our study found that levels of diesel exhaust inside a school bus can be four times higher than those found in passenger cars driving just ahead of the bus. And the diesel levels inside the buses were more than eight times the average diesel-exhaust content of California air."


Why are the real issues related to smog not addressed by the media? Can it be that the financial cost of dealing with the older vehicles is so great the powers that be would rather blame ozone for the smog problem rather than face the real issues? Is the medical use of ozone also playing a factor in this vilification process?


Why are ozone producing air purifiers being vilified as well? Ozone generators have a place Billiga Nike Air Max 360 , for smoke and odor remediation projects and for use in bars, casino's, and other smoky environments. Ozone is also used by the food industry to keep food from spoiling. Furthermore, ozone is used by most municipal water districts to purify the water. Ozone has been used for over 100 years to treat illness. In Germany Billiga Nike Air Max 97 , over 6.5 million doses of ozone have been administered and numerous ozone studies have been conducted showing the medicinal effects in the treatment and cure of everything from cancer to AIDS with medical ozone. In Germany, there are reports of only 30 adverse results from those 6.5 million plus does, mostly from improper administration. One such ozone therapy is an ?ozone sauna.? A plastic body bag that covers everything but the head is fitted with an ozone generator inside that will produce several hundred milligrams of ozone per hour. Within an hour, much of that ozone will be absorbed through the skin and then enter the blood where it can attack cancer cells Billiga Nike Air Max Zero , chemicals, and any foreign substance that shouldn't be there. One can then speculate that the medicinal use of ozone is yet another motive for the vilification of ozone and ozone producing air purifiers given the size and strength of U.S. pharmaceutical drug industry and their lobbying power. Here is what had to say recently on the subject of medicinal ozone:


"In fact numerous ef
