Difficulty: 0

My name is Kevin Teichman and I'm a senior science advisor in the EPA Office of

Research and Development. I've worked at EPA for 33 years and I've seen firsthand

the impactful difference that scientists and engineers at EPA have made to protect

human health and the environment in our nation. A great example of this is

particulate matter both indoors and out. Particulate matter are the microscopic

solids and aerosol droplets that can so easily get into our lungs because they

are small. The sources of particular matter include smoking, vehicles, power

plants, wildfires, and other sources. I was fortunate to work on EPA's environmental

tobacco smoke assessment and that assessment was the first assessment to

show that somebody else's smoking was impacting your health.

Although EPA could not regulate indoor air we were able to contribute to no

smoking policies first in federal buildings, then airplanes, in restaurants

and public spaces. Over my career I also have been fortunate to work on the

national ambient air quality standards for a particulate matter and as we learn

more about the effects of exposures to smaller particles that standard changed.

This has all been possible because scientists at EPA have contributed to a

better understanding of particulate matter sources, exposures, health and

welfare effects, and control technologies. This science has helped protect people

across the nation from heart and lung disease, from heart attacks and

respiratory illness and as I look back I am very proud of the contributions EPA

and in particular Office of Research and Development scientists and engineers

have made to informing impactful policies that protect the American

public, protect the environment both indoors and out in the case of

particulate matter
