Positive Trends in PM2.5 Levels

October 19, 2017Environmental Instruments BlogBy Nikki Wolf

Fine particulate matter (PM_2.5) is an air pollutant that is a concern for people’s health when levels in air are high. PM_2.5are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated.¹

The EPA has been tracking the levels of PM_2.5 in the air for several years and monitor trends in various locations throughout the U.S. This monitoring is all done under the Clean Air Act – one of the most comprehensive air quality laws in the world.

The results of the study are quite positive – PM_2.5 levels are trending down. The graph below shows that from 2000 to 2016 there has been a 42% decrease in the national average of the PM_2.5 in the air.

Despite this improvement, particulates continue to be a major health hazard globally. Mesa is dedicated to providing instruments that use BGI pioneering technology to meet and exceed the requirements for ambient particulate sampling dictated by the U.S Environmental Protection Agency.
