Chemical response of lakes in the Adirondack Region of New York to declines in acidic deposition.
Long-term changes in the chemistry of wet deposition and lake water were investigated in the Adirondack Region of New York. Marked decreases in concentrations of SO4(2-) and H+ in wet deposition haveExpand

Lake variability: key factors controlling mercury concentrations in New York State fish.
A 4year study surveyed 131 lakes across New York State beginning in 2003 to improve our understanding of mercury and gather information from previously untested waters. Our study focused onExpand

Response of surface water chemistry to reduced levels of acid precipitation : comparison of trends in two regions of New York, USA
In light of recent reductions in sulphur (S) and nitrogen (N) emissions mandated by Title IV of the Clean Air Act Amendments of 1990, temporal trends and trend coherence in precipitation (1984–2001Expand

Trends in Mercury Concentrations in New York State Fish
Atmospheric emissions of mercury in the US are being reduced, but worldwide mercury emissions remain high. Mercury is also being removed from many consumer items. Changes over time in mercuryExpand

Chronic and episodic acidification of Adirondack streams from acid rain in 2003-2005.
Limited information is available on streams in the Adirondack region of New York, although streams are more prone to acidification than the more studied Adirondack lakes. A stream assessment wasExpand

Changes in the chemistry of acidified Adirondack streams from the early 1980s to 2008.
Lakes in the Adirondack region of New York have partially recovered in response to declining deposition, but information on stream recovery is limited. Here we report results of Adirondack streamExpand

Lake/watershed sulfur budgets and their response to decreases in atmospheric sulfur deposition: watershed and climate controls
Atmospheric sulfur (S) emissions peaked in North America in the early 1970s followed by declines in S deposition and sulfate (SO42−) concentrations in surface waters. Changes in S biogeochemistryExpand

Use of stream chemistry for monitoring acidic deposition effects in the Adirondack region of New York.
Acid-neutralizing capacity (ANC) and pH were measured weekly from October 1991 through September 2001 in three streams in the western Adirondack Mountain region of New York to identify trends inExpand
