PM 2.5 were measured by using a low volume air sampler (LVAS) that was equipped with an elutriator to separate particulates with more than 2.5-micron size and a fiberglass filter to trap particulates with less than 2.5-micron size at air flow rate of 3.5 liter per minute. Meanwhile, a portable air quality monitor was used to measure CO dan CO 2 .

What is PM 2.5? Particulate matter, or PM2.5, is very small particles in air that are 2.5 micrometers (about 1 ten-thouh of an inch) or less in diameter. This is less than the thickness of a human hair. Particulate matter, one of six U.S. EPA criteria air pollutants, is a mixture that can include organic chemicals, dust, soot and metals. These particles can …

Particulate Matter < 2.5 microns (PM2.5) - airborne particulate matter with a mass median diameter less than 2.5 µm. Numerous studies have linked PM to aggravated cardiac and respiratory diseases such as asthma, bronchitis and emphysema and to various forms of heart disease. PM can also have adverse effects on vegetation and structures, and ...

Similarly, significant decreases are predicted for road transport PM 2.5. While in 1990 79 % of the population was exposed to levels exceeding 1 µ g m −3, this percentage was 58 % in 2001 and 18 % in 2010 (Fig. 9d). The corresponding changes for 2 µ g m −3 were from 27 % (1990) to 8 % (2001) and to zero (2010).

PM 2.5 particles are small enough for you to breath them deeply into your lungs. Sometimes particles can enter your bloodstream. People who are sensitive to air pollution might experience symptoms when PM 2.5 levels are high. This includes people with heart or lung conditions. Symptoms can include: wheezing. coughing.
