Jenkins (Wildlife Conservation Society) chronicles the deposition of acids and mercury from fossil fuel combustion onto the Adirondack Mountains region, and how researchers measured the acid rain and traced it ecological effects. Color graphs and maps illustrate sulfur, nitrogen, calcium, and mercury cycling in both forests and lakes. Previously published as Acid rain and the Adirondacks: a research summary by the Acid Lakes Survey Corporation in 2005. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
