For the second day in a row, the eastern U.S. was enveloped in a hazy beige smog that blocked the skies and sun of early summer.Countless tiny particles from the raging Canadian wildfiresmeasuring 2.5 microns or less in width (30 times the diameter of a human hair)are polluting the air.In New York City, levels of these particulates have soared to nearly 60 times the recommended guideline established by the World Health Organization, according to data collected by IQAir.
