Determination of leachate toxicity through acute toxicity using Daphnia pulex and Anaerobic Toxicity Assays

Acute toxicity of titanium dioxide nanoparticles in Daphnia magna and Pontogammarus maeoticus

Titanium dioxide nanoparticles (nTiO2) are the world's second most widely consumed nanomaterial and large quantities of this material enters the aquatic ecosystem annually. Therefore, understanding the effects of nTiO2 on aquatic organisms is very important. The present study used Daphnia magna as a model freshwater organism and Pontogammarus maeoticus as a brackish water organism to evaluate s...

Acute toxicity test with Daphnia magna: an alternative to mammals in the prescreening of chemical toxicity?

In this study, the association between the acute toxicity of 15 compounds to Daphnia magna, expressed as 24- and 48-h LC(50) values, and the corresponding oral LD(50) values for the rat was tested. Since there was evidence of a strong relationship between the two species, the sample was extended to 54 cases by including the values for acute toxicity to D. magna and rat of more chemicals publish...

Acute toxicity of thallium to Daphnia magna and Ceriodaphnia dubia.

Toxicity Evaluation of Essential oil of Trachyspermum ammi in Acute and Sub-chronic Toxicity Experiments

Background: Trachyspermum ammi is one of the prominent plant in traditional medicine of the east with several medicinal effects such as improvement of stomach disease, digestive disorder, diarrhea, hemorrhoid, bladder stones, respiratory disease and etc. Medicinal plants is one of the important reason of toxicity particularly in children and the elderly therefore, evaluation of the toxic effect...

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...
