"Atmospheric emissions of mercury from various sectors of the Canadian economy have been estimated for the year 1970. A summary of the data presented in this report is given in Table 1, along with estimates for the United States. Of the total 82.2 tons of mercury released through human activities into the atmosphere in 1970, 2.2% resulted from the primary and secondary production of mercury, 32.7% from the consumption of mercury metal, 2.7% from the consumption of mercury compounds, and 62.4% from the inadvertent release of small amounts of mercury in various fuels, wastes, and other materials. The largest single source of mercury emission was the chlor-aIkali industry, which accounted for 32.1% of total emissions."--Abstract.
