Monitoring Ozone Using Portable Substrate-Integrated Hollow Waveguide-Based Absorbance Sensors in the Ultraviolet Range

Abstract: Ozone is an oxidizing molecule used for disinfecting a wide variety of environments, such as in dental clinics, and has most recently been promoted as a sanitizing agent to prevent coronavirus transmission. The easy access to ozone-generating sources also enables their ubiquitous use. However, exposure to ozone may seriously affect human health by amplifying or inducing respiratory diseases and distress syndromes and has been associated with premature deaths from other diseases. In this scenario, miniaturized,… Show more

“…Several countries across the globe have similar air quality standards for health safety. 1,2 At the ground level, the air quality standard for ozone is 60 ppb for 8 h. The concentration range recognized by OSHA for workstations as the occupational exposure limit (OEL) is 50-200 ppb, which is the recommended contact duration. 3,4 The primary source of ozone in the troposphere is the stratosphere, 5,6 while its second source is the photochemical reactions of NO x and volatile organic compounds (VOCs).…”

“…The development of an iHWG for the ultraviolet (UV) range represents a challenging but promising opportunity, especially for gas-sensing applications. , The UV spectrum covers a broad spectrum of gaseous molecules that exhibit pronounced absorption characteristics in the 190–400 nm range, which includes specific hydrocarbons, volatile organic compounds, and certain atmospheric pollutants. Accordingly, optical sensors operating in the UV range have the potential to offer fast response times, suitable sensitivity, and minimal cross-reactivity with other substances. …”
