PM2.5
PM2.5 refers to tiny air pollution particles that are 2.5 micrometers or smaller in size - so small they can only be seen with special microscopes. When candidates mention PM2.5 on their resume, it usually means they have experience measuring, monitoring, or creating plans to reduce these particles that can affect air quality and public health. This is an important measurement used in environmental assessment, air quality monitoring, and pollution control projects. You might also see it referred to as "fine particulate matter" or "fine particles."
