 Hi, welcome to OISOM Academy, let's begin with all you need to know about PM100. Particulate matter is not a single air pollutant, but refers to a complex mixture of solids and aerosols of varying shape, size and chemical composition. They are composed of various chemical species like organic compounds, inorganic ions, metallic compounds, elementary carbon, etc. As the impact of particulate matter exposure on human health directly depends on the size of the particles, they are classified by the diameter for air quality regulatory purposes. The particles with a diameter of 100 micron or less are collectively known as PM100. Examples include wood particles, dust and so on. PM100 is directly emitted from sources such as windblown dust from open land, pollen, spores, mold, dirt, soil erosion and forest fires, burning fossil fuels, dust emission from unpaved roads, crushing and grinding or other such uncontrolled construction activities. PM100 can enter the nose or mouth while breathing and get deposited in the air passages of the body. They may cause adverse health effects such as biologic reactions, heart diseases, silicosis, etc. Short-term exposure to PM100 can aggravate already present respiratory diseases such as asthma, but long-term exposure can affect respiratory mortality. PM100 in the atmosphere causes visible air pollution affecting the aesthetics of the surrounding environment. PM100 monitoring is an efficient way to detect high concentration of particulate matter and prevent high-level exposures. Different working principles for monitoring particulate matter of all sizes in the ambient environment are gravimetric, TOEM, beta attenuation and laser scattering. OISOM's PM sensor works on the active sampling method of laser scattering that counts particulate matter using a highly accurate laser beam. OISOM's DESTROID is an online particulate monitoring system that measures the concentration of various particulate sizes ranging from 1 micron to 100 microns such as PM1, PM2.5, PM10 and PM100 in the ambient air. It can be used for dust monitoring in areas with dust-laden activities like construction, mining, quarrying, ports, metallurgical processes and many more. Real-time particulate matter monitoring using DESTROID can assist in dust separation automation for instance to activate suppressants at the location once the threshold is breached.
