Canada mines and exports white asbestos or chrysotile to developing countries such as India.

The industry says that white asbestos can be used safely.

But a scientific controversy rages around the continued use of white asbestos, and the World Health Organisation says the most efficient way to eliminate asbestos-related diseases, such as lung cancer and asbestosis, is to stop using all types of asbestos.

While the EU has banned all asbestos and the United States has banned many asbestos products, other countries continue to produce and manufacture large quantities of the mineral.

The world's biggest producer is Russia.

It mines more than a million tonnes of Asbestos a year and exports large quantities of it.

Russian scientists say the EU ban is unnecessary, and a world wide ban would be a direct attack on Russian industry and jobs.

They point out the industry now mines only White Asbestos or Chrysotile which they say can be safely handled - unlike banned types of asbestos which have caused deaths.

From Moscow Rupert Wingfield Hayes reports.

The global asbestos industry earns billions of dollars and employs millions of people. It makes materials which perform a great job in buildings, in pipework and in vehicles.

But according to a panel of scientists, which reported to the World Health Organisation, all forms of it are "carcinogenic to humans".

Even though it is banned or restricted in more than 50 countries, white asbestos is widely used in many developing nations, according to "Dangers in the Dust", a joint report by the International Consortium of Investigative Journalists and the ³ÉÈËÂÛ̳.

In the early 20th Century, Turner Brothers Asbestos was the largest asbestos producer in the world.

It owned mines in Canada and southern Africa, as well as factories in the north of England which processed the mineral into a spun yarn.

The company boasted that 'new uses for asbestos are constantly being discovered, the industry may be regarded as having touched only the fringe of its immense possibilities.'

Then, in 1924, an asbestos spinner named Nellie Kershaw died and things began to change.
