Lecture_3 Air Quality Standards

[@hugadarn]

Thanks for the video. Very informative. Would have been good to have a bit more critical material though (eg a practical example of why some jurisdictions have stringent AQ standards (eg CARB) while others do not, ie such decisions are often made in a political context and must balance economics and protection of human health (I realize he touched on this point but it was very cursory)). Thx again.
