Leslie Kaufman reports for the Bloomberg website that a new study suggests that passing more air pollution regulations in New York may not help air quality here. The study released Feb. 12 in the journal Nature showed about half of deaths related to poor air quality in the United States don't occur in states where the pollution entered the atmosphere.
