AIR CHEMISTRY [3 records]

Record 1 2011-03-16

English

Subject field(s)
  • Atmospheric Physics
  • Chemistry
  • Environmental Studies and Analyses
DEF

Set of chemical reactions and associated processes and properties that are specific to the atmosphere and its constituents.

OBS

atmospheric chemistry: term standardized by ISO.

French

Domaine(s)
  • Physique de l'atmosphère
  • Chimie
  • Études et analyses environnementales
DEF

Ensemble des réactions chimiques particulières aux constituants atmosphériques ainsi que les processus et les propriétés qui se rattachent à ces réactions.

CONT

L'acidification des eaux des lacs scandinaves, en Suède notamment, région exclusivement granitique, pose aujourd'hui un problème angoissant. Il est difficile de dire si les émissions locales de SO2 sont seules en cause, ou si des transports à longue distance sont également vraisemblables. Outre la difficulté de suivre avec précision les trajectoires des masses d'air, la complexité des réactions de chimie atmosphérique possibles ou probables ne permet pas aujourd'hui de répondre valablement.

OBS

chimie de l'atmosphère : terme normalisé par l'ISO.

Spanish

Campo(s) temático(s)
  • Física de la atmósfera
  • Química

English

Subject field(s)
  • Air Pollution
CONT

Evidence of increasing precipitation acidity in north-west Europe was first documented in a Swedish government report in 1967 (Odén 1976). An area of enhanced rainfall acidity centred in the Low Countries of western Europe was identified by the European air chemistry study for the period 1955 - 1968 ....
