Book Description
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.

Book Description
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.

Book Description
This research showed runoff pollution can pose a water quality management problem at the Sweetwater reservoir in terms of PAHs. As presently operated, forebay structures in the URDS do not appear effective to control these pollutants. Further studies are recommended to understand settling of PAH containing suspended solids in the forebays in order to optimize their removal from runoff.

Book Description
Polycyclic aromatic hydrocarbons (PAHs) are globally found contaminants, classified into two main groups: petrogenic and pyrogenic. Petrogenic PAHs are introduced naturally into the environment by oil seeps or anthropogenically by spills of crude or refined petroleum product. Pyrogenic PAHs are formed from the incomplete combustion of fossil fuel or biomass and are commonly distributed by atmospheric deposition and urban runoff. The persistence and toxicity of PAHs make them a target for remedial investigations. Otter Creek, northwest Ohio, is a small tributary to Maumee Bay and has been associated with natural oil and multiple incidents of crude/refined oil spills. As part of the greater Maumee River Area of Concern, PAH contamination has been documented, but never attributed to sources. Knowledge of PAH type may help in remedial actions planned for the creek. A modified EPA Method 8270 was used for the analysis of 23 Otter Creek sediment samples by gas chromatography/mass spectrometry (GC/MS). A suite of 44 non-alkylated and alkylated PAHs was identified and quantified in selected ion monitoring mode. PAH source allocation was accomplished through compilation of diagnostic data, including distribution histograms of homologous PAH series, key diagnostic ratios, and principal component analysis. Total PAH concentrations in Otter Creek ranged from 10.9 to 3015.0 mg kg-1. Sites located at the headwaters had relatively low concentrations compared with downstream sites associated with PAH point sources and were considered baseline values of PAH contamination. Pyrogenic PAHs associated with urban background were prevalent in the headwaters section of the creek. As proximity to known point sources increased, total PAH concentrations increased and sediments exhibited mixing of petrogenic and pyrogenic sources. Mixed signatures were predominant over the refinery and residential stretches of the creek. Furthest downstream, the industrial portion of Otter Creek contained the highest PAH concentrations and mainly petrogenic features.

Book Description
Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and assessment of remediation efforts. To more effectively estimate human and ecological health risks, we evaluated the spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) in an urban river using low-density polyethylene passive sampling devices (PSDs). PSDs simulate cell membranes and lipid tissue and accumulate only freely dissolved, and thus, bioavailable contamination. Using PSDs and high-pressure liquid chromatography we measured bioavailable concentrations of 15 priority pollutant PAHs over five years along 18.5 miles of the lower Willamette River including the Portland Harbor Superfund megasite. This area contains several PAH sources including coal tar and creosote sites, which underwent remediation during this study. Additional potential sources of PAHs include combined sewer overflows, urban runoff, atmospheric deposition and petroleum product leaks and spills. Results reveal increased urban bioaccessible PAH loading during wet seasons and high rain events, successful capping of the McCormick and Baxter Superfund site, increased bioavailable PAHs during dredging operations, and the potential for using PSDs for source apportionment. PAH concentrations, loads, and congener ratios changed significantly depending on location, river flow, precipitation, and contaminant removal activities. Our research demonstrates that human and ecological risk varies significantly by season and remediation technique. Additionally, our refined analytical method eliminated 80% of organic solvents and 100% of chlorinated solvents from the sampling method and also reduced labor and cost. Health professionals can apply the findings and refined technology to more effectively assess exposure to pollution.
