This data release contains survival and growth data from 4-d acute and 28-d chronic water-only bioassays to assess the sensitivity of juveniles of the Federally endangered Venustaconcha trabalis (Tennessee Bean) to seven chemicals with different modes of toxic action (ammonia, chloride, nitrite, potassium, cobalt, manganese, nickel). A commonly tested mussel (fatmucket, Lampsilis siliquoidea) was also tested side-by-side with Tennessee bean in chronic exposures.

We conducted multiple toxicity tests to (1) evaluate the survival and growth of juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a standard 4-week and a longer-term 12-week exposures following a method refined from the standard method using two common reference toxicants (potassium chloride [KCl] and nickel [Ni]); (2) evaluate reproductive endpoints from reproductive KCl and Ni toxicity tests. Reproductive toxicity tests started with Fatmucket brooding mature glochidia to five concentrations of K and Ni for 6 weeks. Subsamples of glochidia were then removed from the adults to determine (1) the viability of brooded glochidia; (2) the viability of free glochidia in a 24-h additional exposure; and (3) success of glochidia parasitism. In this data release we report individual biological, chemical, and water quality measurements from each toxicity test.

This data set contains toxicity data from short term 7-day chronic water-only bioassays to assess the effects pH on ammonia toxicity to survival and growth of a juvenile fatmucket mussel (Lampsilis siliquoidea). We conducted 4 concurrent exposures at nominal pHs of 7.0, 7.5, 8.0, and 8.5 with varying ranges of ammonia to capture effect concentrations. This data set has three tables: (1) routine water quality, including measured pH and ammonia (2) survival and dry weight of juvenile mussels, and (3) length measurements of juvenile mussels

This data release includes physical and chemical characteristics of field collected samples from streams and rivers within the Tri-State Mining District (TSMD) as well as toxicity endpoints from chronic water-only and sediment laboratory exposures including survival and growth of the mussel Lampsilis siliquoidea; survival, growth, and reproduction of the amphipod Hyalella azteca; metal concentrations, and various water quality parameters collected during the toxicity studies. Mining in the Tri-State Mining District took place over a large geographic area, with mining taking place in the three states of Missouri, Kansas, and Oklahoma.
