Effects of induced salinity on BOD reaction kinetics of river water samples (Kesan peningkatan kemasinan terhadap kinetik tindak balas keperluan oksigen biokimia 5 hari menggunakan sampel air sungai)

Biochemical Oxygen Demand (BOD) is a typical parameter used in assessing organic pollution strength in surface waters and is normally tested over a 5-day period at an incubation temperature of 20°C (BOD5). The accuracy of this constituent, in assessing organic contamination under brackish conditions...

The accuracy of this constituent, in assessing organic contamination under brackish conditions has always been known to be somewhat limited as elevated concentrations of chloride (Cl-) disrupts microbial activity from osmotic cellular degradation, causing the bottle decay rate, k1, to be effected.
