China’s capital city is suffering through its worst air pollution since May in the wake of its decision to boost coal production to address a power crunch.

The concentration of PM 2.5 particles -- the most-hazardous, tiny particulate matter floating in the air -- soared to 151, according to data from the U.S. Embassy. An air quality index compiled by the capital’s government stood at 182, which officially fell in the “moderate pollution” range.
