The 5-day test protocol with acceptably reproducible results emphasizing carbonaceous BOD has been endorsed by The us Environmental Defense Company (EPA). This five-day BOD test final result can be referred to as the level of oxygen required for aquatic microorganisms to stabilize decomposable organic make any difference under aerobic conditions.[seven] Stabilization, Within this context, may very well be perceived normally conditions since the conversion of food items to dwelling aquatic fauna. Even though these fauna will keep on to exert biochemical oxygen demand from customers since they die, that tends to come about in just a extra steady developed ecosystem like higher trophic stages.[3]
