CONT

Il existe une législation aux termes de laquelle un déversement doit rester dans certaines limites de température, de pH, etc., et ne doit contenir aucune substance dangereuse pour les égoutiers; dès lors, plusieurs industries doivent traiter leurs effluents avant tout rejet dans le réseau public.

OBS

Les processus biochimiques qui se déroulent dans les sols dépendent souvent de l'activité des ions H+ : d'où l'importance du pH en agriculture (amélioration du rendement des cultures quand le pH est compris entre certaines limites).
