Chlorine [is] an element that is found in biological tissues as the chloride ion. The body contains about 100g of chloride and the average diet contains 6-7 g, mainly as sodium chloride. Free chlorine is used as a sterilising agent e.g. in drinking water.

OBS

Used also as a flour bleaching agent and as an aging and an oxidizing agent.

CONT

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 [...]. Agent anti-microbien, présent dans les emballages, le chlore a de très nombreuses applications. Cependant, comme tout outil à la disposition des hommes, il présente des effets indésirables que l'on doit s'efforcer de limiter.

OBS

chlore : Si on fait exception du chlore atmosphérique, où il est à l'état atomique, le chlore se retrouve généralement à l'état moléculaire, soit C12, d'où l'emploi de ce terme pour désigner aussi, de manière elliptique, le chlore à l'état moléculaire.
