The Power of Clean Air: Understanding PM2.5 and PM10 Particles

What are PM2.5 and PM10 particles, and how can we measure them?

PM2.5 and PM10 particles are air pollutants that can have harmful effects on human health and the environment. How can we selectively measure these particles?

Understanding PM2.5 and PM10 Particles

PM2.5 and PM10 particles refer to particulate matter in the air that have a diameter of 2.5 micrometers or smaller and 10 micrometers or smaller, respectively. These particles can come from various sources such as vehicle emissions, industrial processes, and agricultural activities. When inhaled, they can penetrate deep into the respiratory system and cause health issues such as asthma, cardiovascular problems, and even premature death.

Measuring PM2.5 and PM10 Particles

One way to selectively measure PM2.5 or PM10 particles is by using a high-volume air sampler fitted with an electrostatic precipitator. This device applies charges to particles in the air and attracts them to a filter, effectively removing them from the airstream. It is a powerful tool for monitoring air quality and identifying sources of pollution.
