Question
Consider air-water partitioning at a lake where the water temperature is 30oC:a. Calculate the solubility of oxygen (in mg/L) in water at this temperature, and
b. Would a biochemical oxygen demand (BOD) value of 5 mg/L pose a risk to fish? Consider air-water partitioning at a lake where the water temperature is 30oC:

b. Would a biochemical oxygen demand (BOD) value of 5 mg/L pose a risk to fish?
Explanation / Answer
Answer:
A.as per the obeservation from the standard graph by Henry's law
the solubility of the oxygen at 30c would be 7.5mg/l
B. BOD as 5mg/l would not pose any risk for the fishes as striped bass prefer DO levels above 5 mg/l, and most warm water fish need DO in excess of 2 mg/l
