Figure 4. Decreasing blood lead levels in Canadians

Bar chart showing geometric mean blood lead levels in Canadians age 6 to 79 years from the Canada Health Survey conducted in 1978 to1979 which is 4.79 micrograms per decilitre and from the Canadian Health Measures Survey conducted in 2007-2009 which is 1.34 micrograms per decilitre. The chart also indicates that the current blood lead intervention level set in 1994 by the CEOH or Federal-Provincial Committee on Environmental and Occupation Health, is 10 micrograms per decilitre and that in 1978 to 1979, 27% of Canadians had levels which exceeded this guideline, and that in 2007 to 2009, less than 1% of Canadians had levels exceeding this guideline.
