PM2.5 Particulate Matter

Not everyone thinks about what they are breathing. However, it’s a given that we breathe the air around us, and unfortunately, that air can be polluted by various natural and manufactured contaminants. PM2.5 and PM10 are two of the pollutants that can cause harm to people, animals and the environment.

Differences In Air Quality

Have you ever noticed that the air ‘feels’ different in certain areas? The difference is more noticeable when you are in a city or industrial location than when you go off the beaten track in the countryside or the seaside. 

One reason people go for country walks or bracing seaside hikes to ‘clear their head’, is because the air quality in these regions is less polluted than in urban areas. The air is somehow easier to inhale, feels fresher, cleaner even, and you feel better overall.

PM2.5 - ‘Floating Dust’

Tiny particulate matter can be found in a suspension, fluid or solid-state and are sometimes called aerosols. PM2.5 gets its name from its size, which is 2.5µm – an µm is equal to one-millionth of a metre or one-thousandth of a millimetre. 

The composition of this dust is varied and depends on what emissions are local but mainly from industrial, transport and agricultural sources. The smaller the particulate matter, the longer it remains in the air and the further it can travel.

Science has identified that particulate matter, especially PM2.5 is damaging to health. For example, the WHO guidelines 2021 guidelines state that “the annual average concentrations of PM2.5 should not exceed 5 µg/m3, while 24-hour average exposures should not exceed 15 µg/m3 more than 3 – 4 days per year.”

The Danger Of PM2.5

These tiny particulates can be inhaled into the lungs and can pass into the bloodstream due to their size. A wide range of respiratory problems can be caused by PM2.5, especially in children who inhale more air than adults per pound of body weight. The particulates can also exacerbate already established lung problems like COPD. PM2.5 creates more ill-health issues like cancers and cardiovascular diseases because it can enter the blood system. Long-term exposure can cause fatalities. According to WHO statistics, an estimated 7 million premature deaths are caused by exposure to air pollution.

Monitor Your Breathable Air

Those are scary statistics; for the most part, you cannot see PM2.5, so you cannot know the quality of the air you are breathing or the number of pollutants it contains. Environmental Monitors are the company that can help you find out. We offer several services to purchase, hire or rent to monitor your indoor or outdoor air quality. 

As an experienced, well-trained team, we supply the information on air quality levels and advise and educate on air quality prevention, control, and protection.

Please feel free to contact our friendly and knowledgeable team with any questions or concerns you may be having on the quality of the ambient air you are living or working in.
