daily record (2003) 35: E.P.A.’s safe daily levels 377: Wednesday in New York City Source: New York City Community Air Survey and New York State Department of Environmental Conservation Data shows hourly concentrations of PM2.5 particles, measured in micrograms per cubic meter, for seven N.Y.C.
The air in New York City on Wednesday wasn’t just bad by the city’s standards.
It was historically bad, even compared with places around the world that generally experience much more air pollution.
Wednesday’s daily average was the highest since recording in New York began in 1999.
Wednesday’s pollution, of course, was not caused by a power plant or vehicles, but by major wildfires in Canada, mostly in Quebec.
