Book excerpt: This book describes the sources of water contamination by PAHs and their transportation and fate in natural aquatic systems. It then discusses, from the analytical chemist’s view, how to determine the presence of PAHs in water and wastewater, and the changes in PAH concentration during treatment processes. The text examines the removal of PAHs using membrane bioreactors and advanced sludge processes, highlighting results from both demonstration and full-scale plants. It also examines the presence of PAHs in conventional wastewater treatment plants, especially in sludge.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network “Zones Ateliers”, itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.

Download or read book Handbook of Polycyclic Aromatic Hydrocarbons written by Guilherme C. Bandeira and published by Nova Science Publishers. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs) are high molecular weight, aromatic compounds containing two or more benzene rings joined together in different ways. They belong to a group of persistent organic pollutants (POPs); are resistant to degradation; and can remain in the environment for long periods with the potential to cause adverse environmental and health effects. This book discusses the chemistry, occurrence and health issues related to PAHs. Topics include PAHs in foods and herbal medicines; biomonitoring of PAHs by pine needles; thermodynamics and phase behavior of polycyclic aromatic hydrocarbons mixtures; occurrence of polycylic aromatic hydrocarbons in cephalopods; children environmentally exposed to PAHs and at risk of genotoxic effects; analysis of PAHs in environmental solid samples; the chemical and electronic properties of PAHs; and the determination of PAHs in drinking water sources.
Download or read book PAHs written by Peter E. T. Douben and published by John Wiley & Sons. This book was released on 2003-07-25 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.
Download or read book Determination of Polynuclear Aromatic Hydrocarbons in Water and Wastewater by a Gas Chromatographic Ultraviolet Spectrophotometric Method written by RA. Brown and published by . This book was released on 1979 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency and American industry are interested in determining the concentrations of 129 potentially hazardous compounds in water. Included on the recently issued priority pollutant list are 13 polynuclear aromatic hydrocarbons (PNAs) containing from three to six condensed rings. Exxon Research has developed a gas chromatographic, ultraviolet spectrophotometric (GC-UV) method that accurately determines 23 PNAs, including the 13, at the 0.1-ppb (microgram/litre) level and higher in industrial and municipal wastewater effluents. Alkyl-substituted PNAs can be measured and additional compounds added as desired. The method has been verified by analyzing effluents spiked with a variety of PNAs.

Book excerpt: This book presents new insights into the development of different aspects of petroleum science and engineering. The book contains 19 chapters divided into two main sections: (i) Exploration and Production and (ii) Environmental Solutions. There are 11 chapters in the first section, and the focus is on the topics related to exploration and production of oil and gas, such as characterization of petroleum source rocks, drilling technology, characterization of reservoir fluids, and enhanced oil recovery. In the second section, the special emphasis is on waste technologies and environmental cleanup in the downstream sector. The book written by numerous prominent scholars clearly shows the necessity of the multidisciplinary approach to sustainable development in the petroleum industry and stresses the most updated topics such as EOR and environmental cleanup of fossil fuel wastes.

Download or read book Determination of Polynuclear Aromatic Hydrocarbons in Wastewater from Coal Liquefaction Processes by the Gas Chromatography Ultraviolet Spectrometry Technique written by GT. Boyer and published by . This book was released on 1980 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the classes of compounds that may be present in wastewater from coal conversion plants is polynuclear aromatic hydrocarbons (PAH). Since 13 PAHs containing from three to six condensed rings are on the U.S. Environmental Protection Agency (EPA) list of priority pollutants, an analytical method has been developed for the determination of PAHs in process waters from coal liquefaction processes. This method utilizes the well-established gas chromatography-ultraviolet spectrometry (GC-UV) technique to determine the 13 at the 0.1 ppb (micrograms per litre) level and higher. Isomers and twelve additional PAHs are routinely measured, and the technique may be extended as necessary to cover other compounds as well.
