Air pollution of all sorts has declined sharply in the past 25 years according to official figures.2 Nitrogen oxide levels have fallen by almost two thirds from their 1990 peak, and particulates have more than halved over the same period. But the decline has slowed, and recent studies of the health effects of these two pollutants have raised the bar. While pollution is actually lower than it used to be, the damage it does is better quantified.
