Having a corresponding AQI level alongside PM2.5 measurements can help students measure the precise amount of PM2.5 in a certain area and use them to determine the quality of the air. This difference in proportionality is represented in the following graph:
However, keep in mind that the two measurements are not directly proportional to each other as measurements in µg/m3 are representative of the actual amount of PM in the area whereas AQI measurements are subjective to the air quality standards that have been internationally agreed upon for your particular region. PM 2.5 is most commonly measured in units of µg/m3 (micrograms per meter cubed), or through AQI measurements (meter below).ĭepending on the meter you purchase, it may display either one of the units of measurement. There are many types of PM 2.5 meters in the market, with some of them capable of measuring other types of pollutants as well. Long-term exposure to high concentrations of these particles can put people at risk of developing respiratory illnesses, inflammation, trigger asthma and can even lead to lung cancer. They are fine particles that are commonly produced from factories, vehicle exhaust, burning of crops or volcanic eruptions. Particulate Matter (PM) 2.5 refers to particles or compounds which spans less than 2.5 micrometers in diameter. Without further ado, let’s jump into it! PM 2.5 Meter By measuring air quality, students can make sense of the different standards of air quality and recognize when it becomes appropriate to mitigate their effects. These ideas range from qualitative to quantitative methods and promote active discussion on which type of method would prove the most effective in producing reliable data. Hence, we have suggested 8 experimental ideas that teachers can use to actively involve their students to measure air quality. From the release of greenhouse gases, worsening climate change, and burning of fossil fuels, the rate at which pollutants are produced is unprecedented. As pollution is becoming more rampant worldwide, educators are deeply encouraged to teach students about the science of pollution and what they can do to care for the environment.
