Heavy smog posing health hazards covers north China

Nov. 13 (UPI) -- Thick smog hit north China, including Beijing, as cities across the world's second-largest economy are turning up heating for residents, and industrial emissions persist as a cause of pollution.

China's Ministry of Ecology and Environment said Tuesday the heavy smog will last through Thursday owing to "poor weather conditions." Atmospheric conditions will also improve when smog fades beginning Thursday at noon, the ministry said.

Pollutants in China are a combination of emissions from heating systems, industries and diesel cars, Xinhua reported Tuesday.

The South China Morning Post reported the thick smog will push north China into "heavy polluted" territory.

Pollution is expected to include particulates with a diameter of 2.5 microns, or less -- fine matter that poses the greatest health dangers. The pollutants could rise to above 200 micrograms per cubic meter, according to the Post.

The smog forecast is the first for China's winter season.

China's fight against pollution has been postponed because of the government's focus on responding to an escalating tariff conflict with the United States, according to the Hong Kong-based newspaper.

The Beijing Daily reported Sunday pollution in the capital is to reach a climax by Wednesday.

Elderly people and children, as well as patients with heart or lung conditions, have been told to stay indoors during peak pollution periods.
