Month of publication on resource is written in French. Resource was published in March 1991. Includes bibliographical references (pages 74-76). "The recent acidification of precipitation (Likens and Butler, 1981) in North America has given rise to concern on the subsequent acidification of poorly buffered surface waters and on the effects of acid pollutants on forest ecosystems (Morrison, 1984). The greater part of the eastern boreal forest lies on the Canadian Shield where the low mineral content of the surface waters renders it them susceptible to acidification. In addition, the forest soils of this region are generally thin and, under the influence of acidic pollutants, may suffer from accelerated leaching of base cations (Cronan et al., 1978) or the inhibition of biological activity (Stroo and Alexander, 1986)"--Introduction.
