The air quality index in Beijing was 295, indicating “heavy” pollution, the local environmental monitoring centre said.
Beijing, along with the cities of Baoding, Andan, Langfang and Xingtai, in the neighboring province of Hebei, had issued red alerts, the most serious standard.
As of 8 p.m. Monday, the concentration of PM2.5 particulates, highly hazardous particles 100 times thinner than a human hair of 2.5 micrometers in diameter or less, was about 372 micrometers per cubic meter, roughly 15 times the guideline set by the World Health Organization. The agency expects similar levels for the capital on Wednesday as well, saying the smog won’t disperse quickly without the rain that’s expected in the morning down south. China has a four-tier colour-coded weather warning system, with red representing the most severe weather, followed by orange, yellow and blue.
