Do Air Ionizers Produce Ozone and are They Bad for You?

Ozone (O3 or triatomic oxygen) is a pale blue gas that has a pungent odor. Ozone can be generated naturally, for example by lightning or waterfalls, and unnaturally by special devices as ozone generators or when air pollutants expelled from power plants, cars, etc., react chemically to the sunlight. Ozone is present in the atmosphere in low concentrations and in high concentrations in the ...

How Ozone Pollution Works | HowStuffWorks

Ozone can also be found in the troposphere, the lowest layer of the ozone (often termed "bad" ozone) is manmade, a result of air pollution from internal combustion engines and power exhaust and industrial emissions release a family of nitrogen oxide gases (NOx) and volatile organic compounds (VOC), byproducts of burning gasoline and coal.

ozone detection – Oxidation Technologies News

By gas diffusion, ozonecontaining air reaches the sensing element. When electric resistance is changed in the sensing layer, a voltage change occurs. The voltage change is utilized to determine an equivalent concentration of ozone with the aid of a microcontroller. The voltage can also be used to raise an alarm when the sensor’s voltage is compared with a preset threshold voltage (Figure 1).

How can ozone be both good and bad? | HowStuffWorks

­The thing that determines whether ozone is good or­ bad is its location. Ozone is "good" when it is in the stratosphere. The stratosphere is a layer of the atmosphere starting at the level of about 6 miles (about 10 kilometers) above sea stratosphere naturally contains about six parts per million of ozone, and this ozone is very beneficial because it absorbs UV radiation and ...

Ozone is a pale blue gas with a distinctively pungent smell. Ozone gas is a powerful oxidant and has many industrial and consumer applications related to oxidation. This same high oxidising potential, however, causes ozone to damage mucous and respiratory tissues in animals, and also tissues in plants, above concentrations of about 100 ppb. This makes ozone a potent respiratory hazard and pollutant …
