This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae are important components of many aquatic communities that can be sensitive to effects of aquatic pollutants. Standard algal toxicity tests quantify effects on population growth over 3 to 14 days. These population growth tests are useful for environmental hazard assessment but have limitations. These limitations include test duration, pH, nutrient and metabolite changes during toxicity testing, inability to test at the community level, potential interaction between algal media and test materials, and poor control or understanding of the effects of sample volatilization, sorption, biodegradation, photolysis, or hydrolysis on test material toxicity. These test limitations can be addressed in short-term (

Download or read book Toxicity Testing Using a Chemostat Grown Green Alga Selenastrum Capricornutum written by HG. Peterson and published by . This book was released on 1991 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regulatory toxicity testing with algae commonly use 72- or 96-h inhibition of growth by the green algae Selenastrum, Chlorella, or Scenedesmus. The long incubation period is sufficient for the algae to change the composition of the test medium. Organism-induced changes include the release of organics and the uptake of nutrients with accompanying pH changes. Both the released organics and the variable pH can change the chemical speciation of the toxicants; this may alter their toxicity. In addition, the competitive interactions between hydrogen ions and toxicants can affect toxicity as the pH varies. It is shown here that cadmium (Cd) toxicity to Selenastrum capricornutum increases by up to eight times for every unit of pH increase. Copper (Cu) with its different speciation pattern does not vary as much as Cd, and the pattern is different. Because the toxicity of the two metals vary differently with pH, Cd is 500 times less toxic than Cu at pH 6, but Cd is twice as toxic as Cu at pH 10.

Available in PDF, EPUB and Kindle. Book excerpt: Completely revised and updated with 18 new chapters, this second edition includes contributions from over 75 international experts. Also, a Technical Review Board reviewed all manuscripts for accuracy and currency. Focusing on toxic substance and how they affect the ecosystems worldwide, the book presents methods for quantifying and measuring ecotoxicological effects in the field and in the lab, as well as methods for estimating, predicting, and modeling in ecotoxicology studies. This is the definitive reference for students, researchers, consultants, and other professionals in the environmental sciences, toxicology, chemistry, biology, and ecology - in academia, industry, and government.

Download or read book Handbook of Ecotoxicology written by Peter P. Calow and published by John Wiley & Sons. This book was released on 2009-06-05 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Ecotoxicology provides a readily accessible, yet critical collection of information on ecotoxicological testing. Now available in a single paperback volume, this handbook represents excellent value. Part A concentrates on techniques, especially those tests used for prediction. Thorough descriptions of the main tests are provided, followed by critical analyses in terms of ease of handling, repeatability and ecological relevance, and finally, an extensive bibliography citing key documents describing test methods and key papers evaluating them. Part B focuses on the toxicants themselves: summarising their ecological effects, describing ways of predicting effects from physico-chemical properties alone, and describing and discussing fate models. Now available as a single volume in paperback An invaluable reference resource

Download or read book Plants for Environmental Studies written by Wuncheng (Woodrow) Wang and published by CRC Press. This book was released on 2020-02-10 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the problems of using plants in environmental studies is finding current information. Because plants play a key role in environmental studies, from the greenhouse effect to environmental toxicological studies, information is widely scattered over many different fields and in many different sources. Plants for Environmental Studies solves that problem with a single, comprehensive source of information on the many ways plants are used in environmental studies. Written by experts from around the world and edited by a team of prominent environmental specialists, this book is the only source of complete information on environmental impacts, mutation, statistical analyses, relationships between plants and water, algae, plants in ecological risk assessment, compound accumulations, and more. Encompassing algae and vascular plants in both aquatic and terrestrial environments, this book contains a diverse collection of laboratory and in situ studies, methods, and procedures using plants to evaluate air, water, wastewater, sediment, and soil.

Available in PDF, EPUB and Kindle. Book excerpt: The book mainly introduces readers to the development and current status of water quality criteria (WQC) in China and other countries or areas, and proposes a minimum toxicity data requirement (MTDR; i.e., six species from three phyla) as the principle metric for deriving WQC in China. Further, ten model species from 4 different phyla are recommended as domestic test species, and the methodologies for deriving aquatic life criteria, sediment criteria, ecocriteria and nutrient criteria in China are also described in detail. In order to demonstrate the methods, several representative chemical pollutants and aquatic environments are highlighted as examples. The book provides important references for future WQC-related research in China, which will make it of great interest to researchers and graduate students in the fields of environmental science, ecology and aquatic science etc.
