It addresses air pollutants, including the acidifying air pollutants that cause acid rain, as well as ground-level ozone and trace elements. It briefly discusses the anthropogenic sources of these pollutants, their current status, their impacts on forest ecosystems and the issues they cause for Qu\u00e9bec\u2019s temperate forest. Most air pollutants come from combustion of fossil fuels for energy production or transportation. Since the mid-1990s, thanks to pollutant emission reduction programs implemented in Canada and the United States, emissions and ambient air concentrations of most pollutants have declined significantly. Sugar maple (Acer saccharum Marsh.), a dominant species in the northern temperate zone, is especially sensitive to air pollutants and their impacts for ecosystems. Previous chronic pollution of these forests has resulted in significant loss of ecosystem services. However, environmental monitoring is ongoing with a view to documenting ecosystem reactions in the wake of contemporary decreases in anthropogenic emissions of air pollutants in North America.<\/p>\n<p>\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in The Forestry Chronicle 101(2): 306-318 This paper is the third in a series documenting contemporary issues in Qu\u00e9bec\u2019s temperate forest.
