I'm the Data and Advocacy Steward with Public Lab, and am an avid environmentalist living in Durham, North Carolina. My background is in environmental geochemistry, and I am interested in the intersections and overlaps between environmental science and social justice. Joining Public Lab, I am looking forward to getting involved in environmental protection in a more tangible way.
Are there any methods to distinguish where particulate matter in the air comes from?
