Book Description
La surveillance classique de la pollution atmospherique obeit a des contraintes specifiques qui demandent le deploiement de techniques particulieres et couteuses. Ces contraintes ont conduit l'Algerie, comme pays en emergence, a privilegier utilisation d'organismes vivants (lichens, mousses, feuilles des arbres etc..) dans lesquels les contaminants surveilles sont doses: la bio-surveillance. Le but de cet ouvrage est l'etude de l'utilisation d'une mousse, pour quantifier les emissions en metaux lourds, dans le milieu urbain de la ville de Tiaret (Algerie). Cette methode de bio-surveillance demeure necessaire pour completer les outils de veille sanitaire, afin d'orienter la politique publique en matiere de gestion des risques sur l'environnement."

Book Description
This book gives an overview of the relationships between agriculture and air quality, which is an issue of increasing importance for practitioners and policy makers. It provides the keys to understand natural and anthropogenic mechanisms governing emission and deposition of pollutants produced by and/or impacting agricultural activities It identifies how management practices can help mitigating emissions and how public policies on air pollution progressively addressed the agricultural sector This book was written for students, researchers and agriculture actors as well as for public decision-makers

Book Description
Long before "green" issues became a subject of widespread concern, both editors of the present book were heavily involved in research relating to pollutants in the highway environment. The result was the First International Symposium on Highway Pollution in 1983 with subsequent Second and Third Symposia held in London and Munich respectively.The proceedings of these three conferences were published respectively as Volumes 33, 59, and 93 of The Science of the Total Environment which provided individual insights into developing research projects. This book is an attempt at a more coherent overview of highway pollution in which leading international authorities were invited to contribute their works.This book covers all aspects of air, water and noise pollution in the vicinity of highways. Sources, transport and effects are reviewed and control by engineering and legal procedures are considered. The current state of knowledge is put into perspective in this unique work.

Book Description
This book focuses on explaining the distribution of sexual systems (simultaneous hermaphroditism, sequential hermaphroditism, environmental sex determination,dioecy, androdioecy, etc.) among taxa, which remains a major challenge in evolutionary biology. Although significant advances have been made for angiosperms, there is not yet a theory that predicts the sexual system for the majority of animal taxa, and other taxa of plants also remain poorly understood. The problem, particularly for animals, is that sexual systems can be very conservative, with whole phyla and classes being characterized by a single sexual system; for example essentially the whole phylum Platyhelminthes is simultaneously hermaphroditic, whereas the Insecta (Hexapoda) and the Tetrapoda among the vertebrates, are exclusively dioecious. Sex allocation theory on the other hand, suggests that sexual systems should be highly responsive to evolution, changing with population density, life span, patterns of resource availability, etc. The book provides an overview of the topic and then presents a series of chapters, each dealing with a taxon with substantial lability in sexual system in order to identify the factors associated with changes in sexual system in each case. By doing so, the authors reveal factors that have not been considered in formal theory but seem to have a major impact on transitions between sexual systems. This book appeals to a wide readership in fields from zoology and evolutionary biology to botany.

Book Description
This Tema Nord report presents a study based on open information and custom market research to review the most common perfluorinated substances (PFC) with less focus on PFOS and PFOA. The study includes three major parts:1) Identification of relevant per-and polyfluorinated substances and their use in various industrial sectors in the Nordic market by interviews with major players and database information; 2) Emissions to and occurence in the Nordic environment of the substances described in 1); 3) A summary of knowledge of the toxic effects on humans and the environment of substances prioritized in 2); There is a lack of physical chemical data, analystical reference substances, human and environmental occurrence and toxicology data, as well as market information regarding PFCs other than PFOA and PFOS and the current legislation cannot enforce disclosure of specific PFC substance information.

Book Description
This book focuses on the fungi found in one of the most pristine regions on Earth: Antarctica. It discusses the fungal occurrence in all substrates of the region, including soil, seawater, lake and marine sediments, rocks, ice, and snow. It also addresses the impact of climate changes on these organisms, the genomic techniques developed to study them, and how a number of compounds, such as antibiotics and enzymes, produced by the Antarctic fungi can be used in medicine, agriculture and the chemical industry.

Book Description
This volume of the IARC Monographs provides an assessment of the carcinogenicity of fluoro-edenite fibrous amphibole, silicon carbide fibres and whiskers, and carbon nanotubes, including single-walled and multiwalled types. None of these agents had been assessed previously by the IARC Monographs Working Group. The Working Group relied mainly on epidemiological studies to evaluate the carcinogenic hazard to humans exposed to fluoro-edenite fibrous amphibole, an environmental contaminant that was reported to cause mesothelioma in the regional population of Biancavilla, Sicily, Italy. Silicon carbide fibres are by-products of the manufacture of silicon carbide particles by the Acheson process; silicon carbide whiskers are produced by other processes. The evaluations of the fibres and of the occupational exposures associated with the Acheson process were mainly based on epidemiological studies, whereas the assessment of the whiskers--in the absence of epidemiological--was based on carcinogenicity bioassays and consideration of their physical properties. In view of the absence of epidemiological studies on carbon nanotubes and the limited information available from mechanistic data, the evaluations of single-walled and multiwalled carbon nanotubes relied essentially on carcinogenicity bioassays.
