Tissue concentrations are reported on a wet-weight basis. One specimen pool was analysed per species per site; the two species function here as a predator- detritivore contrast rather than as biological replicates, so no within-site variance can be attached to any single value.
This dataset is derived from "Heavy Metal Speciation in Riverbed Sediments and Trophic Transfer to Benthic Fish at Selected Barrages of Punjab", a thesis by Afifa Sehr (24-CUVAS-0082), Cholistan University of Veterinary and Animal Sciences, Bahawalpur, Pakistan (2026).
