Book Description
PCBs and dioxins are among the most toxic organic chemicals and where the latter is an unwanted bi-product primarily from residential wood burning, fires, municipal waste incineration and steel reclamation, PCBs have been widely used in a number of industrial and commercial products and activities. PAHs have carcinogeni/mutagenic properties and are produced when materials containing carbon and hydrogen are burned. The heavy metal mercury is also one of the most toxic chemicals that is being used today and although there are legally binding instruments in force within the EU and globally, which aim to limit the use and spreading of mercury in the environment it is still found in various consumer and commercial products. The use of these chemicals gives rise to emissions to air. This joint Nordic project contributes to improving the emission inventories for mercury, PAHs, dioxins and PCBs related to the sector "Solvents and Other Product Use", which will help the Nordic countries to assess whether they reach the overall environmental objective of clean and healthy surroundings and several targets in the Nordic Environmental Action Programme 2009-2012 and the international air quality conventions such as Convention on Long-Range, Transboundary Air Pollution (CLRTAP). The report is mainly aimed at experts performing the national emission inventories but also policy-makers and the general public may find information on sources to emissions, working procedure of emission inventories and on measures implemented on an international and national level for reducing emissions.

Book Description
This book details three main topics: the screening and characterization of hydrocarbons from air, soil and water; technologies in the biodegradation of hydrocarbons; and the bioconversion of hydrocarbons for biofuel/chemicals, as well as recent developments in the remediation of hydrocarbons and their environmental benefits. The first section focuses on screening methods, qualitative and quantitative analysis of hydrocarbons from soil, air and water environments, speciation of hydrocarbons, and natural bioremediation strategies in such environments. The second section examines technologies for removing hydrocarbon contaminants from various environments, especially advanced technologies for the removal of hydrocarbons and in-situ and ex-situ remediation strategies and problems, as well as concrete case studies. The last section, covering the bioconversion of hydrocarbons for biofuel/chemicals, highlights the biochemicals and bioproducts developed from hydrocarbons, with a particular focus on biochemical and chemical technologies used to produce biopolymers, biofuel precursors and commodity chemicals from hydrocarbons.

Book Description
The automobile is one of the inventions that have made a decisive contribution to human mobility, and consequently it has become an inseparable part of modern human society. However, it is through this widespread use that its negative impacts on the environment have become so highly visible. Achievements in improving the ecological characteristics of the automobile are highly impressive: a modern car emits only a fraction of the amounts of noise and exhaust pollutants produced by its predecessors 30 years ago. The contributions to this book were written by experts, most of whom have been actively involved in the development of modern automobiles and their combustion engines for more than 30 years. They have participated in all phases of the ecological development of the automobile and summarize their experience and know-how in this book .

Book Description
"Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.

Book Description
This third edition of the book has been completely re-written, providing a wider scope and enhanced coverage. It covers the general principles of the natural occurrence, pollution sources, chemical analysis, soil chemical behaviour and soil-plant-animal relationships of heavy metals and metalloids, followed by a detailed coverage of 21 individual elements, including: antimony, arsenic, barium, cadmium, chromium, cobalt, copper, gold, lead, manganese, mercury, molybdenum, nickel, selenium, silver, thallium, tin, tungsten, uranium, vanadium and zinc. The book is highly relevant for those involved in environmental science, soil science, geochemistry, agronomy, environmental health, and environmental engineering, including specialists responsible for the management and clean-up of contaminated land.

Book Description
The volume contains the main papers presented at the 1994 EUROTOX Congress, Basel, Switzerland, August 21-24, 1994. Toxicology has become a less descriptive science because more importance has been placed on the mechanisms underlying toxic effects. This is reflected in symposia and workshops devoted to species differences in organ toxicity, receptor-mediated toxicity and stereochemical effects of xenobiotics. Recent progress in the fields of immunotoxicology, ecotoxicology, and neurotoxicology is highlighted and documented together with the present discussion on harmonized regulatory guidelines.

Book Description
Although the U.S. Environmental Protection Agency presented a comprehensive review of the scientific literature in its 2003 draft reassessment of the risks of dioxin, the agency did not sufficiently quantify the uncertainties and variabilities associated with the risks, nor did it adequately justify the assumptions used to estimate them, according to this new report from the National Academies' National Research Council. The committee that wrote the report recommended that EPA re-estimate the risks using several different assumptions and better communicate the uncertainties in those estimates. The agency also should explain more clearly how it selects both the data upon which the reassessment is based and the methods used to analyze them.
