Abstract:
This dataset reports copper, cadmium, iron, lead, and arsenic concentrations in liver and dorsal muscle of two freshwater fish species, 'Wallago attu' and 'Cirrhinus mrigala', from four barrages on the Indus Basin river system in Punjab, Pakistan - Head Sulemanki, Taunsa Barrage, Head Punjnad, and Head Islam - sampled on 27 June 2026. 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). All values are transcribed verbatim from the source thesis; none has been estimated, imputed, or otherwise generated.
