Reliable and Affordable Laser PM Sensor For Outdoor Particulate Matter Monitoring - 2

1. Why Particulate Matter Measurement Is Important Particulate matter (PM) is a highly prevalent and impactful air pollutant around the world. PM10 Coarse particules Fine particules Upper respiratory tract Lower respiratory tract Very fine particules Alveolus Ultrafine particules Blood/Whole body Particulate matter refers to small size particles, they can enter the body, move into the airways and lungs, and even enter the bloodstream. High PM concentration cause serious acute health problems including asthma attacks, COPD exacerbations, heart attacks. In the long term explosure, it will...

2. Why Outdoor Particulate Matter Monitoring Is More Critical Outdoor air pollution is one of the world’s largest health and environmental problems. PM is a common and first proxy indicator for air pollution. Many countries have legislation that require ambient PM monitoring in cities and industrial & construction worksite. Without measurement there is no control. Intensive grid monitoring becomes more and more necessary. 2005 V.S. 2021 WHO Air Quality Guidelines(AQGs) With the growing awareness for air pollution for human beings, WHO strengthened the standards for PM concentration in air....
