Asbestos is a mineral with long, thin fibrous crystals. The word asbestos (῾ἀσβεστος) is derived from a Greek adjective meaning inextinguishable. The Greeks termed asbestos the miracle mineral because of its soft and pliant properties, as well as its ability to withstand heat.
Asbestos is known to have toxicity. The inhalation of toxic asbestos fibers can cause serious illnesses, including malignant mesothelioma, lung cancer, and asbestosis (also called pneumoconiosis). Since the mid 1980s, many uses of asbestos have been banned in many countries.
Canada’s deadly trade in asbestos
by Mark Bourrie
Canada is starting work this summer on a billion dollar project to renovate its parliamentary buildings and cleanse them of asbestos, which has been found to cause cancer.
The project will take six years to complete but, in the meantime, Canadian government agents are still pushing exports of the fibre. Canada even has gone so far as to argue a challenge at the World Trade Organization that a proposed French ban on asbestos imports would be an illegal trade practice.
Despite recent warnings that asbestos was the cause of 500,000 cancer victims in western Europe alone, Canadian asbestos producers continue to promote and sell their fibre worldwide – especially to developing nations.
Asbestos is used as a binder in cement, as insulation, and in anti-fire walls. It is also a potent carcinogen with a long, well-documented legacy of death.
The danger comes when small asbestos fibres are released and inhaled by labourers. The fibres cause cancerous growths in the lungs, lung lining and abdomen but can take 20 years or more to manifest.
In 1997, Canada exported 430,000 tonnes of asbestos – more than 96% of production – most of it to the developing world. Canada is the world’s second-largest exporter of asbestos after Russia.
Union activists, who have visited India and other developing countries say, however, that the public relations efforts of the government and the asbestos industry are simply window-dressing to hide the fact that most people who work with the natural mineral fibre risk cancer.
Critics of Canada’s asbestos exports say the country is exporting death to protect the profits of a handful of companies and the jobs of 1,600 miners.
“What’s the difference between land mines and asbestos?” asks Dr. Barry Castleman, author of a respected book on the danger of asbestos. “A key difference, of course, is that Canada doesn’t export land mines.”
At the heart of the issue is Canada’s own precarious political situation. All of the asbestos mines in Canada are in Quebec, a predominantly French-speaking province with a separatist government.
Federal and provincial politicians are pushing asbestos exports to prove that they are successful at developing overseas markets, and are protective of Quebec workers. Critics of asbestos exports say the industry would probably be allowed to die if it was centred in any other part of the country.
“Personally, I believe this is all about Quebec politics,” says Canadian Auto Workers Health and Safety director Cathy Walker. “The Canadian and Quebec governments are competing with one another to show just how prepared they all are to protect Quebec jobs.”
The real costs will be borne by the developing world, she says.
Walker just returned from India, where she saw unprotected workers slashing open bags of asbestos fibres. In places where the asbestos was being mixed into cement, clouds of the carcinogenic fibres swirled around workers.
In Britain, the Cancer Research Campaign said in January that its study into the European asbestos-linked cancer epidemic should sound alarm bells everywhere, “particularly in the developing world where uncontrolled asbestos is still very common,” said CRC director Gordon McVie.
Seven of Canada’s top 10 markets are Third World countries. Still, the Canadian government, the asbestos industry and lobby groups are trying to put a good face on the asbestos industry.
Recently, diplomats stationed here were flown to asbestos- producing regions on an all-expense-paid first-class junket.
