Figure 2. Comparison of Canadian anthropogenic atmospheric lead emission profile for 1970 and 2009

One pie chart showing Canadian atmospheric lead emissions in 1970 and one pie chart showing Canadian atmospheric lead emissions in 2009. Pie chart for 1970 indicates total emissions of about 21,400 tonnes and that of this, emissions from automobiles is 65 percent or 14,083 tonnes; non-ferrous mining, smelting and refining is 19 percent or 4,001 tonnes; iron and steel industries is 11 percent or 2,485 tonnes; incineration is 1 percent or 194 tonnes; cement manufacture is 1 percent or 116 tonnes; aviation is 1 percent or 152 tonnes; other is 2 percent or 389 tonnes.

Pie chart for 2009 indicates total emissions of about 260 tonnes and that of this, emissions from base metals smelting and refining is 70 percent or 181 tonnes; aviation is 17 percent or 44 tonnes; mining is 3 percent or 9 tonnes; iron and steel is 2 percent or 5 tonnes; electric power generation is 1 percent or 3 tonnes; other is 7 percent or 18 tonnes.
