Impacts Acadia National Park Natural and scenic resources in
Acadia National Park (NP) are susceptible to the harmful effects
of air pollution. Sulfur, nitrogen, mercury, ozone, and fine
particles impact natural resources including surface water,
wildlife, and vegetation, and scenic resources such as
visibility. Click on the tabs below to learn more about air

Acadia NP. - Nitrogen & Sulfur - Toxics & Mercury Nitrogen and
sulfur from the air—how much is too much? When airborne nitrogen
(N) and sulfur (S) pollutants deposit onto streams, lakes, and
forests, they may cause acidification. An assessment in the
Northeast has identified forests, lakes, and streams in the
region most sensitive to N and S deposition. Also, the project
mapped areas where current levels of deposition exceed the
critical load (Dupont et al. 2005; NESCAUM
