Background: Iron, manganese, and aluminum are three abundant metals on earth and their concentrations have increased in aquatic environments as a result of natural and industrial activities. This study was undertaken to report the median acute toxicity (LC50) and accumulation of the sub-lethal concentration (10% 96-h LC50) of iron (Fe), manganese (Mn) and aluminum (Al) in kutum (Rutilus kutum) ...

Scientists participating in the USGS Abandoned Minelands Initiative have quantified metal concentrations and loadings from mining-related and natural background sources in the upper Animas River of southwestern Colorado, with the goal of guiding remediation decisions by federal landmanagement agencies. We have compared site-specific toxicity thresholds with frequencies of dissolved metal concen...

The introduction of Registration, Evaluation and Authorisation of Chemicals (REACH), requires companies to register and risk assess all substances produced or imported in volumes of >1 tonne per year. Extrapolation methods which use existing data for estimating the effects of chemicals are attractive to industry, and comparative data are therefore increasingly in demand. Data on natural toxic c...

The purpose of the research is study pharmaco-toxicological properties Ornidazole- and Levamisole hydrochloride-based drug. Materials methods . drug were studied in premises Laboratory Preclinical Studies, Faculty Veterinary Medicine, Stavropol State Agrarian University. Acute chronic toxicity, irritant effect was under Guidelines for Studies Drugs (2012). Hematological studies laboratory anima...

Abstract Background Textile dyes which are eliminated as unfixed through the effluent from textile industry cause deleterious effect on fresh water fish. Thus, toxicity tests were conducted using indigo dye Oreochromis niloticus juveniles (mean weight 30.00 ± 0.73 g) a test fish under bioassay system. Varying concentration of 0.00 (control), 0.5, 1.0, 1.5, 2.0, and 2.5 mg/l containing graded le...
