Beijing air pollution soars to hazard level
 |
The air smells of coal
dust and car fumes
Air pollution in the
Chinese capital Beijing has reached levels judged as hazardous to human health.
Readings from both official
and unofficial monitoring stations suggested that Saturday's pollution has
soared past danger levels outlined by the World Health Organization (WHO).
The air tastes of coal
dust and a car fume, two of the main sources of pollution, says a BBC correspondent.
Economic growth has
left air quality in many cities notoriously poor.
Heavy smog has
smothered Beijing for many days, says the BBC's Damian Grammaticas, in the
capital.
By Saturday afternoon
it was so thick you could see just a few hundred meters in the city center, our
correspondent says, with tower blocks vanishing into the greyness.

Even indoors the air
looked hazy, he says.

WHO guidelines say
average concentrations of the tiniest pollution particles - called PM2.5 -
should be no more than 25 micrograms per cubic meter.
Air is unhealthy above
100 micrograms. At 300, all children and elderly people should remain indoors.
Official Beijing city
readings on Saturday suggested pollution levels over 400. An unofficial reading
from a monitor at the US embassy recorded 800.
Once inhaled, the tiny
particles can cause respiratory infections, as well as increased mortality from
lung cancer and heart disease.
Last year Chinese
authorities warned the US embassy not to publish its data. But the embassy said
the measurements were for the benefit of embassy personnel and were not
citywide.
Conclude:
