Mercury Poisoning in the production of fluorescent light bulbs

From the London Times:

WHEN British consumers are compelled to buy energy-efficient lightbulbs from 2012, they will save up to 5m tons of carbon dioxide a year from being pumped into the atmosphere. In China, however, a heavy environmental price is being paid for the production of “green” lightbulbs in cost-cutting factories.

Large numbers of Chinese workers have been poisoned by mercury, which forms part of the compact fluorescent lightbulbs. A surge in foreign demand, set off by a European Union directive making these bulbs compulsory within three years, has also led to the reopening of mercury mines that have ruined the environment.

Doctors, regulators, lawyers and courts in China - which supplies two thirds of the compact fluorescent bulbs sold in Britain - are increasingly alert to the potential impacts on public health of an industry that promotes itself as a friend of the earth but depends on highly toxic mercury.

Making the bulbs requires workers to handle mercury in either solid or liquid form because a small amount of the metal is put into each bulb to start the chemical reaction that creates light. . . .

In one case, Foshan city officials intervened to order medical tests on workers at the Nanhai Feiyang lighting factory after receiving a petition alleging dangerous conditions, according to a report in the Nanfang Daily newspaper. The tests found 68 out of 72 workers were so badly poisoned they required hospitalisation.

A specialist medical journal, published by the health ministry, describes another compact fluorescent lightbulb factory in Jinzhou, in central China, where 121 out of 123 employees had excessive mercury levels. One man’s level was 150 times the accepted standard.

The same journal identified a compact fluorescent lightbulb factory in Anyang, eastern China, where 35% of workers suffered mercury poisoning, . . . .
