Oxygen demanding substances
WebNational Pollutant Discharge Elimination System (NPDES) permits typically have permit limits for oxygen demanding substances: 5-day biochemical oxygen demand (BOD5), ammonia (NH3), and dissolved oxygen (DO). These constituents affect the dissolved oxygen (DO) levels in streams as they naturally decay. WebOxygen demand, chemical EPA Registry Name: Chemical oxygen demand Preferred Acronym: COD Definition: A measure of the oxygen equivalent of the organic matter content of a sample that is susceptible to oxidation by a strong chemical oxidant, usually reported as COD as mg O2/L.
