Sea winds to reduce pollution levels soon
Print Edition
POLLUTION was moderate in Shanghai yesterday as winds brought in pollutants from the northern provinces, said the environmental monitoring center.
The situation is expected to ease today as sea winds sweep in.
The city’s Air Quality Index (AQI) peaked at 153 by 1pm yesterday, with tiny particle PM2.5 being the major pollutant. The districts of Qingpu, Putuo, Xuhui and Jing’an were among the most affected.
Qingpu reported a PM2.5 density of 173 micrograms per cubic meter at 3 m — almost seven times the World Health Organization’s recommended daily standard of 25 micrograms per cubic meter.
“Pollutants carried into Shanghai from the northern part of the country were the major cause (of the pollution),” a Shanghai Environmental Monitoring Center official told Shanghai Daily.
“With the arrival of some east wind from the sea, cleaner air can be expected in the next two days.”
The AQI is forecast to fall back to below 65 — or good — today, with PM10 being the major pollutant.
The lack of wind and high humidity caused fog in the northern and eastern coastal areas in Shanghai yesterday morning.
Due to the haze and poor visibility, Shanghai citizens in some areas missed the “supermoon” last night.
The natural phenomenon happens when a full moon comes in at its closet point to Earth. The next opportunity will not come until November 25, 2034.
Temperatures will drop slightly today and tomorrow, to between 12 and 18 degrees Celsius. The high is forecast to climb back to 21 degrees from Friday.
Today will be mostly cloudy and drizzle is expected for the rest of the week.
