Hydrogen chloride and inorganic chlorides are introduced into the troposphere by volcanic emissions, by seaspray evaporation and by human activity. Removal of these compounds by rain is so rapid that their concentrations decrease rapidly with altitude. Molecular chlorine (Cl2) escaping from industrial processes is also rapidly removed by chemical processes in the atmosphere. 3, record 1, English, - chlorine

Le chlore, dont le nom vient du terme grec chloros, qui signifie vert-jaune, entre, à un titre ou à un autre, dans la moitié des fabrications de la chimie moderne [...].
