Rep. Tina Orwall joins "Capitol Ideas" today to talk about the dangers of ultrafine particles, microscopic pollutants that float down from jet airplanes as a byproduct of burning Jet A fuel, and efforts to site a new or expanded airport in Washington state to take some of the pressure of of SeaTac International Airport, which sits in the middle of her legislative district.

Democratic state Rep. Tina Orwall has learned a lot about ultrafine particles, tiny pollutants (800 times smaller than the thickness of an average strand of human hair). She spearheaded a recent study to find out how prevalent they are in her district, which includes one of the nation's busiest and fastest-growing airports. The results? They're very, very prevalent. She also talks about ongoing efforts to site a new or expanded regional airport to take some of the pressure off of SeaTac International, which is bursting at the seams.
