This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of the hazards resulting from the accidental or deli berate contamination of terrestrial and aquatic environments is in most countries still lirnited to the detection and quantification of the suspected pollutants by chemical analyses. Such an approach is unfortunately hampered by the following constraints : the costs as weil as the technical difficulties of analyzing every individual chemical which may be present in the sampies, and the difficulty of assessing the hazards and risks of environmental contaminations from a set of chemical data. During the last decades the scientific and regulatory community has gradually realized that biological methodologies have to be taken into consideration for an ecologically meaningful assessment of the toxicological hazards of contaminants. Effect evaluations obtained with biological techniques indeed integrate the impact of all the contaminants to which living biota are exposed. Bioassays with selected test species representative for the biological commumtles of the environments under consideration, are now applied more or less regularly to determine toxic and genotoxic effects. Taking into account the species specific and chemical specific character of toxicity to biota, the necessity of a «battery of tests» approach with species of different trophic levels is currently also generally accepted and implemented. It is dear that a balanced partnership between chemical, biological, toxicological and microbiological analyses is always the best strategy for generating the broadest information base on environmental hazards.

Download or read book The Utilization of Bioremediation to Reduce Soil Contamination Problems and Solutions written by Václav Sasek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional reliance on chemical analysis to understand the direction and extent of treatment in a bioremediation process has been found to be inadequate. Whereas the goal of bioremediation is toxicity reduction, few direct, reliable measures of this process are as yet available. Another area of intense discussion is the assessment of market forces contributing to the acceptability of bioremediation. Finally, another important component is a series of lectures and lively exchanges devoted to practical applications of different bioremediation technologies. The range of subjects covers a wide spectrum, encompassing emerging technologies as well as actual, full-scale operations. Examples discussed include landfarming, biopiling, composting, phytoremediation and mycoremediation. Each technology is explored for its utility and capability to provide desired treatment goals. Advantages and limitations of each technology are discussed. The concept of natural attenuation is also critically evaluated since in some cases where time to remediation is not a significant factor, it may be an alternative to active bioremediation operations.

Download or read book Water Contamination Emergencies written by Kenneth Clive Thompson and published by Royal Society of Chemistry. This book was released on 2004 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contamination of water supplies, whether by chemical, biological or radioactive agents, requires a rapid and effective response in order to reduce or avoid impact on the environment or consumers. Using seven major incident case studies (including the Milwaukee Cryptosporidium incident, Chernobyl and the UK Foot and Mouth outbreak), Water Contamination Emergencies: Can We Cope? looks at the complete handling of emergency incidents relating to water contamination emergencies. With contributions from experts involved in real life international incidents, the book also looks at: monitoring requirements; trying to prove the absence of contamination; novel approaches to screening analysis; health risks; the importance of efficient communication; the perception of the public; and the international height of alert situation with respect to potential terrorist acts. Anyone involved in water contamination emergencies, whether researchers and professionals in the water or health industries, or government agencies, should welcome this title as a review of lessons learnt in the past and as an identification of ways in which to improve response in the future.

Download or read book Artemia Basic and Applied Biology written by Th.J. Abatzopoulos and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this volume are to present an up-to-date (literature survey up to 2001) account of the biology of Artemia focusing particularly upon the major advances in knowledge and understanding achieved in the last fifteen or so years and emphasising the operational and functional linkage between the biological phenomena described and the ability of this unusual animal to thrive in extreme environments. Artemia is a genus of anostracan crustaceans, popularly known as brine shrimps. These animals are inhabitants of saline environments which are too extreme for the many species which readily predate them if opportunity offers. They are, thus, effectively inhabitants of extreme (hypersaline) habitats, but at the same time are able to tolerate physiologically large changes in salinity, ionic composition, temperature and oxygen tension. Brine shrimp are gener ally thought of as tropical and subtropical, but are also found in regions where temperatures are very low for substantial periods such as Tibet, Siberia and the Atacama desert. They have, thus, great powers of adaptation and are of interest for this capacity alone. The earliest scientific reference to brine shrimp is in 1756, when Schlosser reported their existence in the saltpans of Lymington, England. These saltpans no longer exist and brine shrimp are not found in Britain today. Later, Linnaeus named the brine shrimp Cancer salinus and later still, Leach used the name Artemia salina. The strong effect which the salinity of the medium exerts on the morphological development of Artemia is now widely recognised.
Download or read book Environmental Toxicity Testing written by K. Clive Thompson and published by John Wiley & Sons. This book was released on 2009-02-05 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an integral component of environmental policy, it has become essential to regulate and monitor toxic substances. Past emphasis has been primarily on analytical approaches to the detection of specific, targeted contaminants, thus allowing chemical characterisation. However, toxicity testing or biological assessment is necessary for ecotoxicological evaluation, and this offers marked benefits and advantages that complement chemical analysis. Key issues to be addressed include identification of pertinent tests, reproducibility and robustness of these tests, and cost considerations.This book examines these issues and describes and explains the approaches that have been developed for environmental toxicity evaluations. Advantages, benefits and drawbacks of the strategies and methods are highlighted. Directed equally at ecotoxicologists, industrial chemists, analytical chemists and environmental consultants, this book is written in a way that will prove helpful to both new and experienced practitioners.
