Effect Of Ozone On Living Things
is ozone gas harmful to human health?
< P > ozone gas is derived from the air we breathe or pure oxygen. Due to its unstable nature, it is transformed back into oxygen, its raw material, after completing its mission. It is a natural disinfectant that does not leave any residue and is not harmful to human health unless inhaled continuously.</p>
EPA, OSHA, USDA and ACGIH organizations in the United States have found that staying at the ozone level of 0.10 ppm for 8 hours has no side effects.</p>
in a room of 9 M2 where a person lives, the amount of ozone can be increased to a maximum of 0.096 ppm.This amount is below the amount that would harm human health.As the square meter area of the room grows,as the number of people increases, as the temperature rises, this ratio decreases even more.</p>
< p>the amount of ozone in the environment should be adjusted according to the size of the space and the density of the unwanted matter .It is recommended to keep high concentration of ozone (0.2 – 0.3 ppm) during non-human hours and to stop the generator for half an hour before the space is opened for use in order to ensure full hygiene.At other times, an ozone level of 0.05 ppm will prevent the formation of new bacteria and microbes.</p>
in a paper published in 1998 at Pennsylvania State University, they examined the claim that ozone’s well-proven microbe-killing property in water should also be valid in air when similar rates are used on a mass basis. The results are summarized below.</p>
| Bacteria | ppb Ozone | Control Number | later the APD control | retry | Living rate ortalama | Min. | Max. |
| E.coli | 300 | 5 | 180,000 | 21 | 0,56 | 0,042 | 0,064 |
| 327 | 3 | 401,000 | 23 | 0,005 | 0,002 | 0,006 | |

| 631 | 5 | 180,000 | 8 | 0,007 | 0,007 | 0,008 | |
| S.aureus | 300 | 5 | 188,000 | 26 | 0,004 | 0,003 | 0,004 |
| 389 | 3 | 195,000 | 26 | 0,004 | 0,003 | 0,004 | |

| 1500 | 4 | 415,000,000 | 18 | 0,003 | 0,003 | 0,003 |
Havadaki ozona maruz kalan Escherichia coli (üst) ve Staphylococcus aureus (alt) kültürleri.Rakamlar saniye cinsinden ozonla temas sürelerini göstermektedir.
Deneylerde elde edilen E.coli ve S.Aureus ölüm eğrileri havadaki ozonun etkin bakteri sterilizasyonu için alt limitinin 0,1 ppm dolaylarında olduğunu göstermiştir.Bu da sudaki bakteri sterilizasyonunun etkinliğine yakın bir etkinliğe işaret etmektedir.
ABD St.Louis kentinde ozonlu hava sirküle edilen ve edilmeyen iki okullarda yapılan gözlemlerde aşağıdaki sonuçlar elde edilmiştir.
