Download or read book Design and Analysis of Chronic Aquatic Tests of Toxicity written by Paul I. Feder and published by . This book was released on 1981 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present investigation considers aspects of the planning of, reporting results from, and the statistical analysis of data arising from chronic aquatic tests of toxicity with fathead minnows. The discussion emphasizes analyses and data displays for the interpretation of qualitative mortality and abnormality data and quantitative weight data. The report consists of nineteen sections. Section I-IV describe the literature search, argue for and present a set of standardized data reporting formats, and contain some suggestions for further improving and standardizing the test procedure. Section V briefly describes the early life stage testing procedure and the resulting data. Sections VI-XIX discuss various topics pertaining to the statistical analysis of such data and to statistical aspects in the design of toxicity tests. Techniques discussed include preliminary graphical displays, tests for homogeneity among tanks within treatment groups, adjustments to account for tank heterogeneity within groups, outlier detection procedures, overall tests for treatment effects, multiple comparions and pairwise confidence intervals of treatment groups with the control group, analysis of variance, regression analyis and parametric and nonparametric dose response curve fits along with associated estimates of 'safe concentrations'. All suggested procedures are illustrated with real examples based on aquatic toxicity data. Several newly developed, specialized computer programs are described to carry out nonstandard analyses.

Available in PDF, EPUB and Kindle. Book excerpt: CHEMOMETRICS AND CHEMINFORMATICS IN AQUATIC TOXICOLOGY Explore chemometric and cheminformatic techniques and tools in aquatic toxicology Chemometrics and Cheminformatics in Aquatic Toxicology delivers an exploration of the existing and emerging problems of contamination of the aquatic environment through various metal and organic pollutants, including industrial chemicals, pharmaceuticals, cosmetics, biocides, nanomaterials, pesticides, surfactants, dyes, and more. The book discusses different chemometric and cheminformatic tools for non-experts and their application to the analysis and modeling of toxicity data of chemicals to various aquatic organisms. You’ll learn about a variety of aquatic toxicity databases and chemometric software tools and webservers as well as practical examples of model development, including illustrations. You’ll also find case studies and literature reports to round out your understanding of the subject. Finally, you’ll learn about tools and protocols including machine learning, data mining, and QSAR and ligand-based chemical design methods. Readers will also benefit from the inclusion of: A thorough introduction to chemometric and cheminformatic tools and techniques, including machine learning and data mining An exploration of aquatic toxicity databases, chemometric software tools, and webservers Practical examples and case studies to highlight and illustrate the concepts contained within the book A concise treatment of chemometric and cheminformatic tools and their application to the analysis and modeling of toxicity data Perfect for researchers and students in chemistry and the environmental and pharmaceutical sciences, Chemometrics and Cheminformatics in Aquatic Toxicology will also earn a place in the libraries of professionals in the chemical industry and regulators whose work involves chemometrics.

Book Synopsis Aquatic Toxicology of Salinity and Silver in Daphnia Magna by : Mark A. Kolkmeier
Download or read book Aquatic Toxicology of Salinity and Silver in Daphnia Magna written by Mark A. Kolkmeier and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral bioassays with the model freshwater cladoceran Daphnia magna have the potential to serve as nontraditional but sensitive endpoints of sublethal stress in the field of ecotoxicology. However, few studies have examined the comparative sensitivity of phototaxis perturbations to standardized endpoints in chronic toxicity testing protocols. D. magna 21 d chronic toxicity studies were conducted with model stressors of salinity (NaCl) and dissolved silver (Ag+). Phototaxis assays of progeny response to relative light changes in small water columns were conducted of each brood. Results indicated predominantly decreased phototactic behavior in comparison to control brood performance at common ecotoxicological thresholds. Phototaxis assays showed effects at treatment levels below the 21-d adult reproduction LOEC value in broods 2, 3, 5 and 6 in the salinity study and broods 2, 5, and 6 in the silver study. Future refinement of robust and potentially highly ecologically relevant behavioral assays such as phototaxis in combination with traditional and nontraditional endpoints may prove useful in characterization of assessment factors.
