Acute aquatic toxicity of arsenic-based chemical warfare agents to Daphnia magna

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...

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...

Assessment of Aquatic Toxicity of River Keya Using Daphnia magna

This study assessed the aquatic toxicity of the River Keya during its passage through the Hsin Chu City, Taiwan. The River Keya receives effluent from the Union Wastewater Treatment Plant of Hsin Chu Science Industrial Park (UWTP-HCSIP) primarily covering more than 500 semiconductors-related high-tech industries. Although the effluent from the UWTP-HCSIP has met the current environmental regula...

Investigation of acute toxicity of cadmium-arsenic mixtures to Daphnia magna with toxic units approach

Th e acute toxicities of cadmium chloride (CdCl2.H2O), arsenic trioxide (AS2O3), and their mixtures to Daphnia magna were investigated by employing the statistical method of aquatic toxicity. Th e data obtained were statistically evaluated with probit analysis method (SPSS 17.0). Th e 24 h LC50 of Cd and As to Daphnia magna was estimated to be 44 μg L−1 for Cd, and 509 μg L−1 for As, respective...
