Vehicle traffic is down.
As side benefits, pollution and mortality are down a bit, too, according to Bloomberg, citing a new study.
Overall levels of nitrogen dioxide dropped by 0.10 micrograms a cubic meter of air, the scientists estimated. Levels fell by 0.73 micrograms a cubic meter in zones where the fee is charged, compared with 0.07 micrograms a cubic meter in areas where it is not. The zone designated the city's most-deprived saw a drop of 0.24 micrograms a cubic meter compared with a drop of 0.02 in the least-deprived parts of town.
There was a less-pronounced decline in levels of fine particles, likely because there are other significant sources of the pollutant, the scientists said. Overall concentrations fell by 0.03 micrograms a cubic meter. The most-deprived area benefited from a reduction of 0.08 micrograms a cubic meter.
Air pollution has been linked to heart disease, cancer, allergies, asthma as well as impaired lung development in children.New York is considering congestion pricing. Could it work in Wisconsin?
