Measurement of exchangeable inorganic phosphate in lake sediments

Description
Summary:A relatively simple short-term equilibration system is compared with a longterm system for use in measuring the amounts of isotopically exchangeable inorganic phosphate in a range of sediments from 8 Wisconsin lakes (see also Wat. Pollut. Abstr,, 1973, 46, Abstr. No. 40). The tabulated results indicate that measurements with the short-term system may be more representative of exchangeability under natural conditions than measurements made in long-term systems. It was also shown that much of the inorganic phosphorus in a large group of Wisconsin sediments is in a form potentially available to aquatic organisms and for interaction with the overlying lake water.
