Acid-vulnerable areas are more numerous and widespread than believed 7 years ago. Lakes and streams in acid-vulnerable areas of northeastern North America have suffered substantial declines in acid-neutralizing capacity, the worst cases resulting in biological damage. Many invertebrates are very sensitive to acidification, with some disappearing at pH values as high as 6.0. However, the recent rate of acidification of lakes is slower than once predicted, in part the result of decreases in sulfur oxide emissions. A discussion of some of the processes that have contributed to the acidification of lakes as well as those that have protected acid-sensitive freshwaters is presented.

酸敏感区的数量和分布范围比 7 年前人们认为的要多得多。在北美洲东北部酸敏感地区的湖泊和溪流的中和能力已经大幅下降，最严重的情况导致了生物损害。许多无脊椎动物对酸化非常敏感，有些在 pH 值高达 6.0 的情况下就消失了。然而，湖泊酸化的最近速度比曾经预测的要慢，部分原因是硫氧化物排放量的减少。本文介绍了导致湖泊酸化的一些过程，以及那些保护了对酸敏感的淡水的过程。作者是加拿大马尼托巴省温尼伯市大学 crescent 501 号，渔业和海洋部淡水研究所的一员。
