Question:medium

A water sample shows high COD but relatively low BOD. This indicates the presence of

Show Hint

Remember: \[ \boxed{ \begin{aligned} \text{High BOD} &\rightarrow \text{Biodegradable organics} \text{High COD with low BOD} &\rightarrow \text{Non-biodegradable organics} \end{aligned} } \]
