Cover title. "The use of di-2-ethylhexyl-phosphoric acid (DEHPA) and tributyl phosphate (TBP) in some proprietary mineral processing plants is causing eutrophication problems. At the request of Environmental Protection, Ontario Region, Environment Canada an experiment was conducted to test the feasibility of finding which chemical might be most responsible for undesirable algal growths. Sufficient DEHPA-P was extracted under laboratory conditions to stimulate growth. TBP-P was not extracted efficiently enough. It was pointed out that this type of experiment will depend largely on the P extraction efficiency and that this can be measured more easily than biological responses"--Management Perspective.
