New Microbiotests for Routine Toxicity Screening and Biomonitoring

Category : Science

Pages : 572
Book Description
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.

Book Description
In the summer of 1999, an international group of experts convened in Jerusalem, Israel, in order to define the major environmental challenges facing humanity at the dawn of the new millennium and - where possible - propose ways of addressing them. Almost 50 selected articles are collected in the present book, which constitutes a striking interdisciplinary combination of state-of-the-art science with the latest views on environmental law, education, and international cooperation. Whilst a major fraction of the book is devoted to water-related issues (water quality monitoring, water and wastewater treatment, water-based international cooperation, and more), other sections deal with timely topics relating to air pollution, biodiversity, conservation, and education. The book is intended for environmental scientists, professionals, and students of all disciplines.

Book Description
This document reviews the current state of knowledge about St. Lawrence belugas, recommends a series of actions for ensuring their survival and proposes an implementation schedule. The goal of the Recovery Plan is to bring population numbers and conditions to a state where natural event and human activities will not threaten the survival of the St. Lawrence beluga whale population. A subsidiary goal is to improve the status from endangered to vulnerable, as defined by COSEWIC.
