Question

Jill Cataldo says:

“And, in 2011, the University of Washington released a study that determined that phosphorous runoff from detergents, even when discharged directly into the Spokane River, never worked as an algae fertilizer: ‘Effluents making their way into the river contained phosphorus in complex molecular forms which are not bioavailable. Algae lack the enzymes necessary to break down this phosphorus, meaning it is essentially harmless.’”

Jonathan Last at the Weekly Standard summarized the study as follows:

“Last month the University of Washington released a study suggesting that some of the phosphorus being discharged into the Spokane River never actually worked as fertilizer for algae to begin with. It seems that not all phosphorus is alike. Some of the effluents making their way into the river contained phosphorus in complex molecular forms which are not bioavailable. Algae lack the enzymes necessary to break down this phosphorus, meaning it is essentially harmless. The study was a useful reminder that all science is settled. Until it’s not.”

Explanation / Answer

As the thoery says that the phosphorus was not being utilized by algae so how did the concentration declined.

Error margins are also high so this might be a decrease in axcuracy of the results
