Figure 2. Line graph of calculated apparent consumption of asbestos by major asbestos-consuming countries, 1920-1990. Data from tables A1-A10. Figure 3. Line graph of calculated apparent consumption of asbestos by major asbestos-consuming countries, 1995-2003. Data from tables A11.A19. The vertical scale differs from that in figure 2 because asbestos consumption generally decreased after 1990.

Figure 1. Estimated world production of asbestos in 2003. Figures listed are in metric tons. Afghanistan, North Korea, Romania, and Slovakia also produced small amounts of asbestos estimated to be 10 metric tons for each. Figure 4. World production of asbestos, by type, from 1900 to 2003. About 2.81 million metric tons (Mt) of amosite, 460,000 metric tons ofanthophyllite, 173 Mt of chrysotile, and 3.92 Mt of crocidolite were produced from 1900 to 2003. Sources: U.S. Geological Survey, 1901-1921, 1924-1932, 1997-2005; U.S. Bureau of Mines, 1934-1996. Figure 5. World production of asbestos, by country, from 1900 to 2003. Total production from 1900 to 2003 was Brazil, 5.12 million metric tons (Mt); Canada, 61.2 Mt; China, 8.57 Mt; Greece, 0.92 Mt’ Italy, 3.87 Mt; Kazakhstan and Russia (combined), 70.4 Mt; South Africa, 9.93 Mt; Swaziland, 1.80 Mt; the United States, 3.29 Mt; Zimbabwe, 9.14 Mt; and other countries combined, 6.42 Mt.
