These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in invertebrates, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation; radioactivities for small rodents were previously presented at https://doi.org/10.5066/P9HARTQ4. Histopathology results are given for liver and kidney lesions generally associated with metals toxicoses in small rodents. Samples were collected at the Pinenut Mine (active mining) and Arizona 1 Mine (post-production) in the Grand Canyon watershed. The non-mineralized reference sites were Little Robinson Tank and Wild Band Reservoir (Valley pocket gophers only). Results for the pre-production site (Canyon Mine) were previously presented at https://doi.org/10.5066/F7QF8R16.

Elemental and radionuclide exposures and uptakes by small rodents, invertebrates, and vegetation at active and post-production uranium mines in the Grand Canyon watershed
The effects of breccia pipe uranium mining in the Grand Canyon watershed (Arizona) on ecological and cultural resources are largely unknown. We characterized the exposure of biota to uranium and co-occurring ore body elements during active ore production and at a site where ore production had recently concluded. Our results indicate that biota have taken up uranium and other elements (e.g., arseniAuthorsDanielle M. Cleveland, Jo Ellen Hinck, Julia S. Lankton - Connect
