Available in PDF, EPUB and Kindle. Book excerpt: Ecological Toxicity Testing provides a critical comparison of toxicity tests at different levels of biological organization from cells to landscapes. While ecological toxicity tests can be designed at any of the many levels of complexity and on spatial scales ranging from square millimeters to square kilometers, the uses to which this information can be put often differs with scale. In the past decade, tests at all levels have been refined and subjected to critical evaluations of their predictive accuracy. This text/reference includes evaluations of toxicity test systems at various scales and complexities by expert practitioners. It also offers broader analyses of the effects of scale on endpoint selection, test design and analyses, and chemical sensitivity.

Available in PDF, EPUB and Kindle. Book excerpt: A multispecies toxicity test is described that uses indigenous microorganisms. The test is suitable for both laboratory and field, is inexpensive, replicates easily, and uses extremely inexpensive materials. An additional advantage is the use of an important ecological rate process as an end point; therefore the test is superior to test using lethality as an end point. The test can be carried out using organisms collected from a site of interest or from a specific ecological resource area. Site-specific or synthetic dilution water may be used. The major drawback is a requirement for significant taxonomic ability. However, more general chemical measures such as ATP biomass, chlorophyll biomass, or heterotrophic index may substitute for species identification. Although this test has been used in a variety of freshwater ecosystems in the United States and has been validated to a limited degree in the People's Republic of China, a wider data base is required before it can be generally used.

Download or read book Development of Techniques for the Evaluation of Toxicant Impacts to Multispecies Systems written by and published by . This book was released on 1994 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research program, new methods of data analysis were applied to the analysis of multispecies toxicity tests using three complex toxicants. The water soluble traction of the turbine fuels Jet-A, JP-4 and JP-8 have been examined as stressors for two microcosm protocols, the standardized aquatic microcosm (SAM) and the mixed flask culture (MFC). The SAM is a 3 L system inoculated with standard cultures of algae, zooplankton, bacteria, and protozoa. In contrast, the MFC is 1 L and is inoculated with a complex mixture of organisms derived from a natural source. Analysis of the organism counts and physical data were conducted using conventional and newly derived multivariate nonmetric clustering methods and computer visualization techniques. Several fundamental discoveries regarding the impacts of toxicants on ecological systems were made. The first is that recovery of an ecosystem in the sense that it returns to the original or reference state is not a property of these systems. In fact, it is unlikely that recovery is a property of other larger ecological systems. In our experiments the various treatment groups incorporated the information as to toxicant concentration that was expressed after periods of so- called recovery. The differentiation of the treatment groups occurred even after the elimination of the toxicant from the test system. Another fundamental discovery is that multispecies toxicity tests are not repeatable, although within one experiment the replicates of a treatment group are replicable. In other words, initial conditions are important. The outcome of this research may lead to a new viewpoint in describing the impacts of toxicants on complex ecological systems. This viewpoint is described as the Community Conditioning Hypothesis.

Available in PDF, EPUB and Kindle. Book excerpt: Many techniques developed by computer scientists in the field of artificial intelligence (AI) are currently being used as standard, state-of-the-art technology. These techniques have proven their value and validity in medicine, geology, agronomy, and astronomy time and again, often beating human experts at their own game. We present here an analysis tool for multispecies data based on nonmetric clustering, an AI technique developed specifically to aid in the interpretation of complex ecological data sets. This technique uses AI search to find an appropriate and meaningful characterization of a multivariate system. After appropriately characterizing the system in this fashion, the relationship between this characterization of the system and the critical environmental variables (pollution, toxicity, etc.) can be quantitatively analyzed to aid in the assessment of the effects of the environment on the system. A priori endpoints or indices are not necessary; the data are allowed to determine the variables that best separate treatment from controls.

Download or read book Introduction to Environmental Toxicology written by Wayne Landis and published by CRC Press. This book was released on 2017-09-29 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fifth edition includes new sections on the use of adverse outcome pathways, how climate change changes how we think about toxicology, and a new chapter on contaminants of emerging concern. Additional information is provided on the derivation of exposure-response curves to describe toxicity and they are compared to the use of hypothesis testing. The text is unified around the theme of describing the entire cause-effect pathway from the importance of chemical structure in determining exposure and interaction with receptors to the use of complex systems and hierarchical patch dynamic theory to describe effects to landscapes.
