ozone detection in South Korea

Factors controlling surface ozone in the Seoul ...

Ozone is produced rapidly under highly elevated NO x and VOC concentrations, which may lead to severe surface O 3 pollution (Jacob, 1999). Many metropolitan areas across the globe have suffered from extreme O 3 pollution, with severe exceedances of the National Ambient Air Quality Standards (NAAQS). For example, in North America and

Observationbased modeling of ozone chemistry in the Seoul ...

The Seoul Metropolitan Area (SMA) has a population of 24 million and frequently experiences unhealthy levels of ozone (O3). In this work, measurements taken during the KoreaUnited States Air Quality Study (KORUSAQ, 2016) are used to explore regional gradients in O3 and its chemical precursors, and an observationallyconstrained 0D photochemical box model is used to quantify key aspects of ...

UV Sensitivity to Changes in Ozone, Aerosols, and Clouds ...

Feb 01, 2014· Abstract. The total ozone (O 3) and aerosol optical depth (AOD) at 320 nm have been observed from the ultraviolet (UV) measurements made at Yonsei University in Seoul, South Korea, with Dobson and Brewer spectrophotometers, respectively, during 2004– daily datasets are analyzed to show the sensitivities of UV radiation to changes in O 3, AOD, and cloud cover (CC) together with …

Ozone Detector, Trioxygen, O3 gas equipment GazDetect

Ozone health effects Ozone (O3) taint varies from colorless to blue with a bleachlike pungent smell, detectable from , ozone is a strong oxidizer and can ignite explosions. Although its toxicity depends on several factors (temperature, pressure, concentration), ozone is very harmful for the breathing system (lungs, nose, throat) and can irritate the eyes.

Ozone Detection | Detectors Available at AirMet Scientific

Ozone is a bluish gas at room temperature with a pungent odour usually detectable by smell at around ppm. In chemical jargon it is called an allotrope, which is another form of the element oxygen (chemical symbol O) with a different molecular structure (O 3 O 2). Ozone is an even more powerful oxidising agent than oxygen. Hazardous ...
