This dataset contains the results of a laboratory chronic bioassay with 6-week-old juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a 28-day zinc exposure (120 and 240 micrograms zinc per liter) with endpoints of survival and growth (biomass and length) following standard ASTM methods. Surviving mussels were transferred from the control and treatment groups into a culture pond and their survival and growth were monitored for 56 days. In this data release we report individual biological, chemical, and water quality measurements from the laboratory toxicity test exposure and pond grow-out period.

This data set includes mortality data from acute toxicity tests with juveniles of the mussel, Lampsilis siliquoidea exposed to 6PPD and 6PPDQ. Concurrently collected analytical chemistry and general water quality measurements are included.

This data set contains toxicity data from 24- and 96-hour water bioassays to assess the effects of a Syngenta Crop Protection product on early life stages of a freshwater mussel. We used ASTM International methods to conduct tests with juveniles and glochidia of the freshwater mussel Lampsilis siliquoidea. Analytical chemistry and water quality analysis results are included as well.

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

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.
