Acute Toxicity of Thallium to Daphnia magna and Ceriodaphnia dubia

Acute toxicity of thallium to Daphnia magna and Ceriodaphnia dubia.

Lethal and sublethal effects of azulene and longifolene to Microtox(R), Ceriodaphnia dubia, Daphnia magna, and Pimephales promelas.

The data from this study were needed to investigate the aquatic toxicity of the natural compounds azulene and longifolene, which were representatives of nearly 500 compounds of 19 chemical classes tentatively identified in Laurentian Great Lakes fish (Hesselberg and Seelye 1982; Passino and Smith 1987). There are growing concerns over the potential toxic and ecological effects of these hydroand...

Aquatic acute toxicity assessments of molybdenum (+VI) to Daphnia magna.

Generally, molybdenum (Mo) metals in the environment are very rare, but wastewater discharges from industrial processes may contain high concentrations of Mo, which has the potential to contaminate water or soil if not handled properly. In this study, the impact of three common compounds of hexavalent Mo (sodium molybdate (Na2MoO4‧2H2O), ammonium molybdate ((NH4)6Mo7O24‧4H2O) and molybdenum tri...

Influences of water chemistry on the acute toxicity of lead to Pimephales promelas and Ceriodaphnia dubia.

The acute toxicity of lead (Pb) was examined for fathead minnows (Pimephales promelas; 96-h) and daphnids (Ceriodaphnia dubia; 48-h) in waters modified for hardness (as CaSO₄), dissolved organic carbon (DOC; as Aldrich humic acid) and alkalinity (as NaHCO₃) for parameterization of an acute freshwater biotic ligand model (BLM). Additionally, acute (96-h) and chronic (30-d) bioassays were perform...
