Deposition of hydrogen ions is closely linked with rainfall amount. Although most of the region covered by the network had hydrogen ion inputs of about 0. 5 kg ha^-1 yr^-1, there were areas with much larger amounts of hydrogen deposited, exceeding 1 kg ha^-1 yr^-1.  1, record 1, English, - kg%20ha%2D1%20yr%2D1

Des valeurs pour l'absorption foliaire de l'ammoniac atteignant au maximum 30 kg ha^-1 an^-1 ont été calculées, bien qu'une valeur moyenne de 5 kg kg ha^-1 an^-1 soit proposée pour la France. Les taux d'absorption de l'azote et de l'ammoniac dépendent sans doute du taux de pollution et des concentrations relatives de ces deux composés dans l'air.  1, record 1, French, - kg%20ha%2D1%20an%2D1

The potential is high for widespread environmental degradation, from acid rain and other pollutant deposition, because hydrogen ion concentration(acid, H+) in the aquatic environment is a critical factor controlling most chemical reactions.  1, record 2, English, - pollutant%20deposition

Les précipitations n'ont sans doute qu'une influence faible sur l'extension de la pollution atmosphérique. Nous connaissons mal leur rôle sur les retombées des polluants au sol.  1, record 2, French, - retomb%C3%A9es%20des%20polluants

Deposition patterns for hydrogen and sulfate ion are similar to that of pH on this scale, with the pH 5 contour typically corresponding to a hydrogen ion deposition of 10 mg m^-2y^-1(10 meg m^-2y^-1) and to an excess sulfate(i. e., with seasalt sulfate deducted) ion deposition of ca. 1 g S m^-2y^-1(10 meg m^-2y^-1).  1, record 3, English, - seasalt%20sulfate

Because sulfur dioxide is the main precursor of acidity, and because understanding of the atmospheric behaviour of sulfur is most advance, sulfate and sulfur dioxide, in addition to hydrogen ion, are frequently used as reliable indicators of the acid deposition phenomenon.  1, record 4, English, - atmospheric%20behaviour
