First, to recap, from the “Why EPA proposal to put high-polluting diesel trucks back on American roadways is a bad move” post (Part 1), a “glider” truck is: “one where … Read more

Why EPA proposal to put high-polluting diesel trucks back on American roadways is a bad move

The U.S. Environmental Protection Agency (EPA) is once again in the spotlight, this time by its proposing to allow high-polluting diesel “glider” trucks to operate on America’s roads.

Fine particulate matter in the air: Health-impacting at any concentration?

I discovered a really interesting article about the Air Quality Index (AQI) titled: “Air Quality Index – time for a rethink?” written by Clive Stott in the Dec. 2017 issue of the Woodsmoke Climate Change News newsletter on pages 14 and 15.
