 Hi, welcome to Oizom Academy, let's begin with all you need to know about ozone. Ozone is naturally present in stratosphere called good ozone, as it protects and shields the Earth's surface from harmful effects of the sun's UV radiation. However, when it is formed just above the Earth's surface, it highly impacts the human health and welfare, making it bad ozone. Ground level ozone is a critical air pollutant with three oxygen atoms. It is a highly combustible reactive pale blue glass with a distinctively pungent irritating smell that resembles chlorine bleach. Its odor can be detected at 0.1 ppm concentrations. Sources of ozone are from forest fires, emissions from vehicles such as cars, trucks, buses, aircraft, construction activities, agricultural equipment, power plants, painting and dry cleaning activities, fuel handling, and storage and other industrial emissions. Due to its high oxidizing potential, ozone reacts with a wide range of cellular components causing damage to mucus and respiratory tissues in humans, animals as well as plants at levels. Ozone can irritate the eyes, nose, throat, and the respiratory system causing coughing and uncomfortable sensation in the chest. It can aggravate respiratory diseases such as asthma and bronchitis. High level of ozone inhalation can cause heart diseases, reduce lung capacity and continue to harm the lungs even after symptoms disappear. Ozone affects the photosynthesis of trees and plants and impairs the growth. An accumulation of ozone leads to formation of smog which is a powerful eye irritant. Ozone monitoring is an efficient way to detect the accumulation of high levels of ground level of ozone that we are exposed to and alerts when a certain level is exceeded. Different working principles for ozone monitoring in the ambient environment are UV photometry, gas phase chemiluminescence, semiconductor, and electrochemistry. At OIZOM, we measure ozone on principle of electrochemical sensing. It operates based on diffusion of ozone molecules into the sensor which results in the production of an electrical signal proportional to the ozone concentration. OIZOM's polytron is an ambient air quality monitoring system capable of monitoring more than 30 parameters including gaseous pollutants like carbon monoxide, carbon dioxide, socks, knocks, dust particulates like PM 2.5 and 10, noise, and weather parameters like rainfall, wind speed, and wind direction. Real-time monitoring of ozone levels helps in calculating the air quality index to deliver health advisories as well as formulating an action plan to meet standards. Polytron is deployed across several cities, campuses, universities, and is used for drawing actionable insights to tackle the rise in ambient ozone concentrations. With this, I hope you now know all about OIZOM. For any questions or suggestions, please contact us. Thank you and happy learning.
