Field observations and experimental measurements of the partitioning coefficient ( K d ) of 7 Be in fresh water show that it varies inversely with the solids concentration at typical environmental values (up to 30 mg/1). This behavior is similar to that of many other metals and organic pollutants, which means that 7 Be may be useful as a tracer of the movement of these substances in the water column. However, the wide range in the percentage of 7 Be adsorbed by solids over this range of concentrations (over 50%) means that in order to use 7 Be either to measure total sedimentation rates or to trace lateral sediment movement it will be necessary to monitor changes in sediment concentration over the area and time period of interest. The wide scatter in our data at both high and low solids concentrations suggests that other factors also affect K d . Until these factors are identified, application of our results to other systems will be risky. At high (greater than 100 mg/1) solids concentrations over 90% of 7 Be is associated with the solid phase, so it may be a useful tracer of reworking rates in bottom sediments. 7 Be has a slightly greater affinity for the solid phase in fresh water than in seawater.
