The BOD can be described as carbonaceous BOD (CBOD) for extremely diluted samples or in samples through which nitrification was inhibited. The real difference in BOD between portions of the sample incubated with and without nitrification inhibition may be the nitrogen oxygen demand (NOD). The NOD also can be estimated from the entire ammonia nitrogen concentration in milligrams for every liter (exact as components per million) multiplied by 4.
