@ Uptake factors calculated from contaminant concentrations measured in mayflies and sediment sample: collected from subreaches 3.03 and 4.04 and reach 18. > Average mercury uptake factor was not calculated using the mayfly uptake factor from reach 18 ir the Tennessee River. The mercury concentrations in mayflies and sediment in reach 18 showed obviou: differences compared to the Oak Ridge Reservation sites. This may be a result of mercury speciatio1 found off-site. CNR = not renorted Table 1. Sediment to mayfly uptake factors for the Clinch River/Poplar Creek System
