Yesterday, the Shanghai Environmental Monitoring Center advised all the elderly, young, and infirm to remain indoors due to a wave of fog-fostered “light” air pollution that is sweeping the city. The “fog,” ( also known by its real name, smog), blew in from central and eastern China and delayed and cancelled flights from Shanghai to destinations in the north.
But despite smog thick enough to harm your health and delay flights, officials claim that everything is tip top:
Today the city is expected to have good air quality, second-best in a five-tier category.
According to the center’s real-time monitoring data, PM10 particulates started to rise at 1am yesterday and peaked at 10am. Then the density dropped quickly in the afternoon, with visibility in most areas of the city improving to 5 to 10 kilometers, reported the Shanghai Meteorological Bureau.
Starting tomorrow, with the strengthening of a warm and wet air current from the southwest, drizzle is expected to return to the city for at least three days. But temperatures will not change much. The daily high is forecast at 7 to 8 degrees Celsius, after lows around 2 to 4 degrees, said the bureau.
The same authorities released similarly oh-so-sincere information concerning the smog two days ago:
Influenced by the fog, air quality in Shanghai almost reached the “polluted” level, according to the Shanghai Environment Monitoring Center, under the PM10 standard. The content of nitrogen dioxide and sulfur dioxide was also relatively high.
Sounds like they’re pulling a Beijing, conveniently confusing fog with serious pollution.
If “light” air pollution is dire enough to force us indoors, then what qualifies as “heavy”? When they say air quality almost reached the “polluted” level, whose standards are they measuring by, Earth’s or Jupiter’s?
acid rain drizzle they highlighted will arrive soon to wash away some of the haze, since the fog that shrouds their reports doesn’t appear to be dissipating anytime soon.
When is that PM2.5 monitoring standard being installed again?
