What fraction of the total metal flux into lakes is retained in the sediments? / by Jerome 0. Nriagu and Henry K.T. Wong. : En13-5/86-75E-PDF
"The concentrations of, and deposition rates for, the pollutant metals (Pb, Cu, Zn, Ni, and Cd) and the rare earth elements are reported for the sediments and settling particulatesin a large, remote lake (Lake Opeongo) in the Algonquin Provincial Park, Ontario. Using a mass conservation model based on the rare earth elements, it is estimated that only 40-60% of pollutant metals getting into the lake is retained by the sediments. The low retention rate may explain the widely reported intra-basin and intra-lake differences in metal contents of sediments and casts some doubt on the use of pollutant metal profiles in retrospective assessment of the human contribution to the metal flux into many lake basins"--Abstract, p. 1.
