Gases | Free Full-Text | Safe and Effective Use of Ozone ...

Airborne Ozone concentrations were measured by an ozone analyzer (model 401, Advanced Pollution Instruments, San Diego, CA, USA), with a detection limit of ppb. Ozone levels of – ppm for 20–112 min time guaranteed 90% and 99% of inactivation, respectively. For all the tested viruses, the ozone concentration required for the same inactivation level was lower at 85% RH than at 55%.

Evaluation of Ozone Exposure from use of Electrostatic ...

the ventilation system on, the exposure was never above the detection limit of the tube. The Riverside ESDA remained below the PEL until the 60-minute reading was taken. More specifically, after 15 minutes the ozone levels started to increase with a high level ( ppm) reached after 60 minutes. This exceeded not only the PEL, but the STEL as well. When the exhaust hood was turned on ...

Sensitive detection of ozone by a practical resorufin ...

· The detection limit of the probe for O3 is nM, which corresponds to an ozone concentration of mg m(-3) in air in this study and is lower than the international ambient air quality standard of mg m(-3). More importantly, the proposed probe is worth popularizing, and its applicability has been successfully demonstrated on both the determination of O3 in real ambient air samples and ...
