Comparison 3erween Right Counties Adjacent to che Asbestos-Producing Areal a.-.c ;?*.; Selectee Counties To compare lung cancer mortality races in the coun ties surrounding the asbestos-producing areas wich another group of counties in which no asbestos miners are likely to reside, the rates were computed on the basis of figures for the years 1950 through 1955. The eight counties selected for comparison were Argenteuil, Chateaugay, Mor.tmagny, Portneuf, Richlieu, Rlvieredu-Loup, St. Hyacinthe, and Terrebonne, mainly because they re present a wide geographic distribution throughout the Province. The counties selected because of their proximity to the asbestos mines include Arthabaska, 3cauce, Drummond, Frontecac, Megantic, Richmond, Sherbrooke, and Wolfe. Table 25 shows the number of lung cancer deaths for che years 1950 through 1955 for each of these counties, and a mortality rate, based on the adult male population in 1952. To emphasize the comparison Megantic County has been shown separately, as has the Province of Quebec and also the Pro vince with the eight "asbestos-producing" counties subtracted. Be cause of its unique lung ciactr death rate, Montreal el Isle de Jesus has also been listed In order to provide further comparison.
