Beijing issues first red alert as air pollution hits hazardous levels

Chad Serrate:

Beijing’s city government earlier today released a red alert for pollution. Schools, construction, and car use have been halted to help aid the people. Although they are generally normal as of now the red alert has been issued to help keep people safe from the extreme amounts to come in the next several days. Beijing had around 256 micrograms per cubic meter of poisonous particles. 25 micrograms is considered unsafe… Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions.
