In this chapter, the effects of air pollutants from the roasting beds and smelters on Sudbury area lakes are examined. A rather novel approach has been used to track the lake water quality changes that occurred in the past century. This approach uses the rapidly expanding science of paleolimnology, the study of the fossil record in the lake sediments. In the absence of long-term data, paleolimnological techniques using biological remains in lake sediment cores are being used extensively to provide quantitative assessments of past water quality in North America (Charles et al. 1990; Dixit et al. 1987, 1992c) and Europe (Battarbee et al. 1990).
