Heat Increases the Level of Tropospheric Ozone
Heat increases tropospheric ozone level has heat added to usual traffic in Madrid and a half of the pollution measurement stations in Madrid beyond the level of health protection by ozone. No rain and no wind, but many cars and no political will to reverse the situation. Gallardón Mayor was reelected in office for four years. That, I hope I’m wrong, mean four more years of increasing pollution in the capital of Spain.
The so-called bad or tropospheric ozone is produced as a result of a photochemical reaction that increases when the nitrogen oxide pollution is high and the solar incidence increases, explained the organization Ecologists in Action. On Tuesday May 24, 2011, at eleven at night, a total of 16 of the 23 stations of the capital there were over 100 micrograms per cubic meter of nitrogen dioxide (NO2). Weather forecasts predict more heat. Forecasts predict political stagnation.
It is not a new situation, if at all. It occurs every year from April to late August. Ozone production increases and decreases each day as the solar intensity. By becoming more oblique incidence of sunlight on the surface in late August when the summer draws to a close, low ozone production significantly.
In the rest of the Community of Madrid is also the phenomenon. Alcalá stations, Fuenlabrada, Torrejón, Alcorcón, Colmenar Viejo, Majadahonda, Arganda, San Martin de Valdeiglesias Guadalix Algete Orusco Atazar and have reached levels above 120 micrograms per cubic meter. The same has happened at five stations in the capital’s heavy traffic away from downtown: Barajas, Vallecas Eixample, El Pardo, Juan Carlos I and Three Olives.
The current regulations can not overcome those 120 micrograms per cubic meter on average in eight hours and more than 25 days a year. The European Union already has a very serious warning about the Madrid City Council, notice that they seem to have fallen on deaf ears. The threshold at which authorities are obliged to inform the population, by contrast, stood at 180 per cubic meter micrograms for one hour. This threshold has not been surpassed so far this year and the peaceful citizens breathe polluted air.
One of the electoral promises of the mayor of Madrid has been to give priority to this problem. Hopefully, this time, they deliver what it promises. Meanwhile, it discourages physical activity, the athletic work in the middle of the day.

Water Treated With Ozone
What is water treated with ozone?
Water treated with ozone is a form of purification and water purification plants, i.e, a water treatment system. Specifically Ozone (O3) is a colorless gas with strong oxidizing capacity of organic matter, hence its use to disinfect water.
Thus it can be reused for both drinking and for irrigation. Even small devices can be installed to treat water with ozone in the home or the tanks or other devices for pools larger.
How does the water treatment with ozone?
Water treatment with ozone is based, as mentioned, the large capacity of oxidation that has this gas on organic matter. In fact, after the element fluorine is more capable of oxidation.
Which produces a fairly rapid and effective destruction of all they are organisms, including the dreaded virus and bacteria. This results in a germ-free water suitable for use in the above terms.
Benefits of water treatment with ozone
The advantages of ozone-treated water are diverse and notable for its greater efficiency compared to chlorine. The latter being the most common water disinfectant and used.
Treating water with ozone allows not only the elimination of harmful bacteria but also kills viruses that chlorine can not destroy.
- Ozonation of water is between 600 and 3,000 times more effective than chlorine, because it takes far less amount of ozone than chlorine to achieve the same effect.
- The ozone water treatment does not increase the content of inorganic salts, toxic chemicals in the water.
- Ozonation is cheaper than super-chlorination and is the same economic investment that a normal chlorination, but prices are decreasing as the ozonation technology is improving.
- Treating water with ozone eliminates odors and flavors that can produce some organic substances.
Disadvantages of water treatment with ozone
- Ozonation has the disadvantage that ozone has an active life in the water about twenty minutes on average.
- Water treated with ozone must be installed in situ and the means to do because it can not be transported.
- Ozonation can produce nitric oxide or nitric acid, producing corrosive effects on the devices used to treat water with ozone.
- Ozonation in the case of operators who work with big machines to treat water should take precautions in their use and exposure to ozone. These should be provided to safeguard their health, as the oxidizing power of ozone can affect the eyes and lungs.
