Chemical and biological data from chronic bioassays with native Spea multiplicata exposed to field-collected water or sediment from the Pinyon Plain Mine containment pond in Arizona, USA, or single metals in water-only tests

The dataset reports biological endpoints (survival, growth, developmental stage, and body burden of selected metals) for larval spadefoot toads (Spea multiplicata) in laboratory-based exposures to 1) field-collected water or sediment from a containment pond at the Pinyon Plain Mine in Arizona, USA, during its pre-production phase and 2) six concentrations of copper or cobalt in water-only bioassays. Also reported are data on water quality and the concentration of metals in the test media during the assays.
