So, What Exactly Is PM2.5? How Do We Measure Microns In Air Pollution?

Air quality is an important aspect of our health and well-being, and one important aspect of air quality is the presence of particulates. Particulates are tiny particles suspended in the air, and they can come from a variety of sources such as industrial emissions, vehicle exhaust, dust, and wildfires. In this blog post, we will take a closer look at the various micron levels of particulates and how they contribute to air quality.

Particulates are measured in microns, which is a unit of measurement equal to one-millionth of a meter. Particulates can be divided into several categories based on their size, with the most common being PM10 and PM2.5.

PM10 particulates are particles that are 10 microns or smaller in size. These particulates can include dust, dirt, and pollen, and they are mostly produced by human activities such as construction and agriculture. PM10 particulates can be inhaled deep into the lungs and can cause respiratory and cardiovascular problems, including asthma, bronchitis and emphysema.

PM2.5 particulates are even smaller, measuring 2.5 microns or smaller. These particulates are produced by burning fossil fuels, such as those emitted by cars, trucks and industrial activities. Typically the majority of contributors of this size are found outside the home.

It's important to note that these particulate measurement are just a representation of the air quality, and other factors such as VOCs, sulfur dioxide, and nitrogen oxides also play a role in air quality.

In conclusion, particulates are tiny particles suspended in the air and are measured in microns. Particulates can be harmful to our health and can cause respiratory and cardiovascular problems. It's important to take into account different particulate measurements to evaluate the overall air quality. Reducing man-made activities that contribute to particulate pollution, such as the burning of fossil fuels, and taking steps to improve air quality, such as using public transportation, walking or biking instead of driving, and purchasing energy-efficient appliances and vehicles can all help to improve air quality and protect our health.
