This book was released on 2015 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discharge of wastes into the lower Mahoning River in Northeastern Ohio since the 19th century has resulted in the accumulation of toxic hydrocarbons, including PAHs, in the river channel and river bank sediments. This study characterizes the polluted bank sediments and evaluates the feasibility of cleanup using in situ bioremediation. Characterization was undertaken in order to study the feasibility of in situ bioremediation. This was accomplished through the collection of 208 samples from 37 soil borings from both banks at five locations along the river. Samples were then analyzed by grain-size analysis and hydraulic conductivities were estimated using the Hazen method. Soil borings also revealed the following: depth to groundwater, depth to bedrock, the upper and lower limits of hydrocarbon contamination, and the thickness of the hydrocarbon contamination in the river banks. Slug tests were performed at four locations to evaluate hydraulic conductivity in very fine-grained sediments, which could not properly be evaluated by the Hazen method. Flow between the groundwater in the bank and the river channel was monitored at four locations for a period of up to one year. Monitoring confirmed the active exchange of flow between the river channel and the banks. This exchange is capable of recontaminating the river's channel by transporting the dissolved contaminants from the bank, via groundwater if the banks are not remediated. PAHs were analyzed in soil samples taken from five locations which verified PAH impact at all four locations. Based on groundwater flow directions, sediment makeup, hydraulic conductivity distribution, thickness of contamination, and PAH availability, this study suggests first, the probability of leaching from impacted bank sediment to groundwater and second, based on the values of hydraulic conductivity that in situ bioremediation is feasible.
Download or read book The Seine River Basin written by Nicolas Flipo and published by Springer Nature. This book was released on 2021-01-30 with total page 430 pages. 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 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 Wastewater Treatment written by Amy J. Forsgren and published by CRC Press. This book was released on 2018-10-08 with total page 260 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Polycyclic aromatic hydrocarbon PAH dispersion and deposition to vegetation and soil following a large scale chemical fire written by A A. Meharg and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs) were determined in soil and vegetation following a large scale chemical fire involving 10 000 ton of polypropylene. In comparison with sites outside the plume from the fire, PAH concentrations were elevated in grass shoots (by up to 70-fold) and in soil (by up to 370-fold). The pattern of PAH dispersion under the plume was dependent on the physical-chemical properties of individual PAHs. The lighter, least hydrophobic PAHs were dispersed into the environment at greater distances than heavier, more hydrophobic PAHs. At the most distant sampling point (4.5 km) under the plume, the low molecular weight PAHs were still considerably elevated in vegetation samples compared to control sites. Dispersion appeared to be regulated by the compounds partitioning between the vapour and particulate phase, with dry particulate deposition occurring closer to the fire source than gaseous deposition. For all PAHs, the fire resulted in greater contamination of soils compared to grasses, with the relative ratio of plant/soil contamination decreasing as hydrophobicity increased.

Available in PDF, EPUB and Kindle. Book excerpt: This book reviews Polycyclic Aromatic Hydrocarbons (PAHs) and Nitropolycyclic Aromatic Hydrocarbons (NPAHs) contamination in the context of environmental pollution in Asia. It is comprised of the following sections: 1. Fundamental Chemistry and General Characteristics; 2. Analytical Methods; 3. Emission Source and Atmospheric Behavior; 4. Atmospheric Polycyclic Aromatic Hydrocarbons and PM2.5; 5. Polycyclic Aromatic Hydrocarbons in Marine Environments; 6. Metabolic Activation/Toxicities; and 7. Environmental Standards and Guidelines. This volume concentrates on the Far East due to the massive consumption of coal and petroleum in China, which has led to considerable levels of air pollution. High concentration of atmospheric PM2.5 in Beijing have been reported since January 2013 and exposure to such high concentrations may cause respiratory, cardiac and lung diseases. Gathering contributions from international experts, this volume provides a valuable reference guide for global researchers and students interested in learning from the East Asian experience.
