particles, mist & dust
We monitor the mass concentration of PM 1, 2.5, 4 & 10, the data is stored but we only report PM 2.5 & 10 on the dashboard as these are the two standard measures currently referred to by the World Health Organization and other notable health bodies.
WHO guidelines state that exposure in a 24-hour period to PM2.5 should be limited to 15 µg/m3 and 45 µg/m3 for PM10.
However, there are no safe exposure limits to this size of particles.
Manufacturing processes, e.g., grinding, welding, cutting and machining operations create airborne particles.
Small particles less than 2.5 micrometres in diameter are referred to as PM2.5.
PM2.5 is especially dangerous to health because they bypass many of the body’s defences and can enter the lungs, where they can move to the alveoli and enter the bloodstream.
PM10 particles are tiny enough to enter the lungs and throat. PM10 can cause coughs, runny nose, and itchy eyes. With high PM10 levels, health problems related to the heart and lungs may be more pronounced. Some of the indicators include wheezing, chest tightness, and difficulty breathing.
what to do
Steps should be taken to reduce the exposure to Particulate Matter, identify the source of the particles and eliminate or introduce engineering controls to improve air quality and reduce risk of exposure.
