There are two basic pathways whereby acid precipitation can impact a terrestrial ecosystem. It can impact directly on the foliar surface of the plants themselves, causing a direct effect on the leaf or stem of the plant, or it can indirectly affect plants, through effects on the soil. Regarding the latter, next to nutrient impoverishment and mobilization of toxic elements, acidic substances in precipitation can induce changes in root function, and reduce the number of essential microorganisms.

OBS

"Acid" and "acidic" are generally synonymous. However, in those instances where one is used in opposition to the other, "acidic" takes on the meaning of "acidifying".

En 1968, le Suédois Svante Oden [...] démontre que, «dans les pays nordiques de degré d'acidité des précipitations avait progressivement augmenté et que de grandes quantités de substances acidifiantes - essenttiellement des composés sulfureux - provenaient de régions industrielles d'Europe centrale et de Grande-Bretagne et seraient la cause de l'acidification de lacs et de rivières en Scandinavie».

OBS

Dissolved salts and minerals in the ground water are carried away by rivers and streams to the oceans. Although plants slow down this process by taking up the dissolved material from the ground water and returning it to the soils as they drop their leaves or die, litter as well as acid substances from the atmosphere add acidic materials to the soils.

Jusqu'à ces dernières années, on considérait que les pluies étaient le mécanisme principal par lequel les substances acides se déposaient.
