Includes bibliographic references : p. 9-11. "Historical records preserved in sediments show that the lakes are extremely sensitive to metal emissions from the smelters in the Sudbury basin. From the observed quick response, a strong capacity for rapid recovery (de-acidification) of acid-stressed lakes in then area is deduced. The study thus emphasizes the need for curtailing the emissions of acidic and acidifying substances as a critical step in reducing lake acidification as well as in rehabilitating many of the afflicted lakes"--Abstract.
