What does pm10 mean?
PM10 is particulate matter 10 micrometers or less in diameter, PM2.5 is particulate matter 2.5 micrometers or less in diameter.
PM2.5 is generally described as fine particles.
By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width..
Is pm10 a dust?
When someone talks about PM10 they are referring to particles smaller than 10 µm. These particles include dust, pollen and mold spores. Conversely, when someone references PM2.5 they are referring to particles smaller than 2.5 µm. These smaller particles include combustion particles, organic compounds and metals.

5 standard (12.0µg/m3). EPA also is setting the 100 value of the index at the level of the current 24-hour PM2. 5 standard, which is 35 µg/m3. An AQI of 100 is the upper end of the “Moderate” range, and the level above which EPA begins cautioning at-risk groups.

Is the pm10 visible?
Dust and smoke are visible examples of PM10, but more than 90 percent of particulate matter isn’t visible to the naked eye. We call these substances “fine particulate matter” or “PM2. 5.” The particles have a diameter of less than 2.5 micrometers, which means they can only be seen underneath a microscope.
What happens if you breathe unhealthy air?
Even though you can’t see it, the air you breathe can affect your health. Polluted air can cause difficulty breathing, flare-ups of allergy or asthma, and other lung problems. Long-term exposure to air pollution can raise the risk of other diseases, including heart disease and cancer.
What particle size is most harmful to human health?
Some particles less than 10 micrometers in diameter can get deep into your lungs and some may even get into your bloodstream. Of these, particles less than 2.5 micrometers in diameter, also known as fine particles or PM2.5, pose the greatest risk to health.

Which two pollutants are the greatest threat to human health?
Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country.
What is pm10 in air quality?
PM10 are very small particles found in dust and smoke. They have a diameter of 10 micrometres (0.01 mm) or smaller. PM10 particles are a common air pollutant. We measure PM10 at some of our air monitoring sites.
Can PM 2.5 be removed from body?
Part of the PM2. 5 inhaled cannot be removed by the lymphatic system and enters the blood circulation via diffusion. Then, the inhaled PM2. 5 goes into the heart, kidneys, and other organs.
How is pm10 measured?
To measure PM10 and PM2. 5, extract a sample of gas at a predetermined constant flow rate through an in-stack sizing device. The particle-sizing device separates particles with nominal aerodynamic diameters of 10 micrometers and 2.5 micrometers.
How can pm2 5 and pm10 be reduced?
Take additional steps to keep pollution in your home low.Avoid using anything that burns, such as wood fireplaces, gas logs and even candles or incense.Keep the room clean – but don’t vacuum unless your vacuum has a HEPA filter. … Don’t smoke.Be cautious when the weather is hot.More items…

Due to small in size both PM2. 5 and PM10 particles act as gas. When you breathe, these particles they penetrate into the lungs, which can lead to cough and asthma attacks. High blood pressure, heart attack, stroke etc.
Is pm10 or pm2 5 more harmful?
PM2. 5 is more likely to travel into and deposit on the surface of the deeper parts of the lung, while PM10 is more likely to deposit on the surfaces of the larger airways of the upper region of the lung. Particles deposited on the lung surface can induce tissue damage, and lung inflammation.
