What Is Particulate Matter?
/The American Lung Association has published an insightful article about particulate matter (PM) that explains the topic well. Particulate matter consists of tiny particles such as dust, dirt, soot, smoke, and liquid droplets. While some particles are visible, many require a microscope to be seen. PM is categorized by size: larger particles are called PM10, while finer particles are known as PM2.5, which pose the greatest health risks.
Sources of Particulate Matter
Particulate matter comes from various sources, including:
Cooking: Frying, grilling, or using gas stoves.
Combustion Activities: Smoking, burning candles, and using fireplaces.
Household Products: Cleaning agents, air fresheners, and aerosol sprays.
Hobbies: Woodworking, metalworking, and crafting.
Biological Sources: Mold spores, dust mites, and cockroaches.
Outdoor Air: Vehicle emissions, wildfires, and industrial activities. Particle pollution can enter buildings through windows and ventilation systems.
Health Impacts of Particulate Matter
Inhalation of PM2.5 can penetrate deep into the lungs, causing irritation and exacerbating conditions like asthma and COPD, as well as leading to pneumonia, heart disease, stroke, and lung cancer.
Sensors like Decentlab's DL-PM | Particulate Matter, Temperature, Humidity and Barometric Pressure Sensor for LoRaWAN® and DL-IAM | Indoor Ambiance Monitor including CO₂, TVOC and Motion Sensor for LoRaWAN® help keep air quality in check, ensuring safer air for all.
