The five-day test protocol with acceptably reproducible final results emphasizing carbonaceous BOD has long been endorsed by The us Environmental Protection Agency (EPA). This five-day BOD test outcome might be described as the level of oxygen essential for aquatic microorganisms to stabilize decomposable natural issue below aerobic circumstances.[6] Stabilization, In this particular context, may be perceived on the whole conditions since the conversion of meals to dwelling aquatic fauna. Despite the fact that these fauna will continue on to exert biochemical oxygen demand since they die, that tends to occur inside of a extra steady progressed ecosystem together with greater trophic amounts.[three]
