Harbin China Chokes on Poisonous Smog
B. McPherson
Air pollution affects us all.
Harbin China is choking on thick, poisonous smog. The
financial success of the PRC is exacting a heavy toll on its citizens. The
northern Chinese city has been hit with early cold weather and city authorities
have responded by ramping up electrical production. The source of energy to
produce electricity is coal fired plants which spew pollution.
A perfect brew of conditions has served to create this
health crisis. The cold weather necessitating a ramp up in coal burning,
farmers burning off stubble in their fields, factories that ignore pollution
guidelines, high humidity and a lack of wind have all contributed to the
situation.
Visibility is down to only a few metres in the soupy air. According
to the official Chinese news source, Xinhua, sight is limited to 100 metres or
less, but in the pictures they show, visibility fades out within about 10
metres. People who venture onto the streets are attempting to filter some of
the pollution out by using medical masks or pieces of clothing. Freeways have
been shut down, schools have been closed and the international airport was
forced to close for the duration.
Health of the citizens will be affected over the long term.
Immediate effects will be irritation of the eyes, nose and bronchi from the
chemicals and particulates in the air. More long term effects will include
chronic respiratory diseases and cancers. The most dangerous particles in air
pollution are not the tiny ones that people can see or that dirty clothing,
they are the nanoparticles that sink into the lungs and either stay there or
are gathered into the body to cause mischief in many areas.
The World Health Organization has set a safe level for these
nanoparticles at a maximum of 25 per cubic metre of air. Instruments in Harbin
are recording levels of 1000 per metre3 .
China’s major cities suffer from heavy air pollution, made
worse in the colder months. Beijing has been coping with increasing smog in
recent days as well. Government authorities have announced plans to cope with
the growing crisis.
Air pollution has recently been named by WHO as a world
crisis, constituting a health hazard as great as second hand cigarette smoke.
