1,300 Chinese Children Near Smelter Suffer Lead Poisoning

More than 1,300 children have been poisoned by a manganese factory in central China, the state media reported today, amid growing fears about the prevalence of heavy metal pollution nationwide.

The
exposure of mass lead contamination in Wenping township, Hunan
province, is the second case in as many weeks, prompting accusations
that the authorities have failed to adequately regulate toxins that
build up over time.

A local government official told the Xinhua news agency
that tests of children living near the smelter showed that 60-70% had
unhealthy levels of lead in their blood. With tests continuing, more
positive cases are expected.

The authorities closed the factory last week and detained two executives on suspicion of "causing severe environment pollution".

The
plant reportedly opened in May 2008 without the approval of the local
environmental protection bureau within 500m of a primary school, a
middle school and a kindergarten.

Although the factory had only
been operating for a year, the blood of 1,354 local children was found
to have more than 100mg of lead per litre, the limit considered safe.

A gradual build up of lead in the bloodstream can lead to anaemia, muscle weakness and brain damage.

The
plant is unlikely to have gone ahead without support from the local
government. Many poor districts ignore environmental regulations to
attract investment, and Hunan is notorious for its heavy metal
industry. The Wugang city government said it had demanded an overhaul
of more than 100 plants, including seven other smelters.

But the
problem is likely to be nationwide because authorities are not obliged
to conduct expensive tests for heavy metals, which tend to accumulate
over time rather than be emitted in noticeable bursts.

In a separate case in Shaanxi, northern China, last week, 615 children tested positive for lead poisoning attributed to a nearby smelter, which is now due to cease operating this Saturday.
