Atmospheric deposition of reduced nitrogen onto nutrient-limited semi-natural vegetation (unimproved grasslands, heathlands, blanket bog) can cause a shift in the balance of species in these sensitive systems because the nitrogen has a nutrient effect on plant growth.
Ecological effects of air pollution can include long-term changes in water quality, soil chemistry, and plant species composition, as well as bioaccumulation of toxics in fish, birds, and wildlife.
