Kinetically influenced terms for solute transport affected by heterogeneous and homogeneous classical reactions
Jean M. Bahr
1990, Water Resources Research (26) 21-34
Simulation of transport affected by heterogeneous or homogeneous reversible reactions requires a choice between local equilibrium-based and kinetics-based models. The error associated with the use of equilibrium-based models is equivalent to the error of neglecting certain mathematical terms in the governing kinetics-based transport equations. Identification and evaluation of these kinetically...

Holocene paleoclimatic evidence and sedimentation rates from a core in southwestern Lake Michigan
Steven M. Colman, Glenn A. Jones, R. M. Forester, D.S. Foster
1990, Journal of Paleolimnology (4) 269-284
Preliminary results of a multidisciplinary study of cores in southwestern Lake Michigan suggest that the materials in these cores can be interpreted in terms of both isostatically and climatically induced changes in lake level. Ostracodes and mollusks are well preserved in the Holocene sediments, and they provide paleolimnologic and paleoclimatic...

Can we determine the biological availability of sediment-bound trace elements?
Samuel N. Luoma
1989, Hydrobiologia (176) 379-396
It is clear from available data that the susceptibility of biological communities to trace element contamination differs among aquatic environments. One important reason is that the bioavailability of metals in sediments appears to be altered by variations in sediment geochemistry. However, methods for explaining or predicting the effect of sediment...
