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 Anthropogenic Impacts as Revealed from Sediment Cores from Punderson Lake Ohio written by Ronald A. Van Blarcum and published by . This book was released on 2015 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Sediment core archives provide a history of data useful for serving as a long-term monitoring reserve to evaluate chronological events of contamination to lake systems. This could be an effective tool for continual environmental management, monitoring and potential restoration efforts. This method is also very cost-effective without the addition of a water quality monitoring station on site. Taking 3 sediment cores from Punderson Lake Ohio for analysis has allowed associating variations in select metals to anthropogenic events or activities; we can determine a time frame with limited uncertainty and resolve the intensity of anthropogenic contamination to the lake starting with post World War II contamination till the present. We used sedimentation rate in conjunction with radiometric dating methods of 137Cs to establish a timeline through the cores. Applying mass depth g/cm2 (Matisoff and Whiting, 2011) and core segmentation intervals (1cm) we can remove issue of porosity and compaction. Selected trace elements (As, Cu, Mn and Pb) were studied in these sediment cores. We can parse natural crustal sources of sediment input from anthropogenic sources using a method known as enrichment factor (EF) (Feng et al., 2004). This method requires the normalization of trace metal concentration against Al into an index/dimensionless data form (Essien et al. 2009). EF index implies a severity of contamination in a sediment interval allowing for the consideration of environmental impact, status of pollution and possibly source the contamination of the select trace metal. We can then plot EF over time to obtain relative burial times of the excess trace metals. We can then make a comparison to other regional lakes to see how anthropogenic source contamination appears in other systems. We used diatoms as a biological component as they are sensitive to ecosystem/environmental changes and preserve well in buried sediment. Therefore; diatoms can be seen as responding to possible human influences that are changing the habitat or quality of the lake. We found correlations within the core showing trace element pollution related to anthropogenic activities. Primarily we can see strong signals of Pb and As in earlier portions of the core indicative of industrialization and fossil fuel burning of the time. We also see a rise in Cu enrichment at the top of the core which, is linked to CuSO4 additions to the lake. Diatoms confirm that the CuSO4 is having an impact on biotic components of the lake particularly changing their community structures. It is important to consider the benefits of this type of study. Future benefits such as building and periodically updating a data base that can be used to track a lake systems contamination levels and provide invaluable insight into remediation and site maintenance efforts.

Download or read book Applications of Paleoenvironmental Techniques in Estuarine Studies written by Kaarina Weckström and published by Springer. This book was released on 2017-02-13 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this edited volume is to introduce the scientific community to paleoenvironmental studies of estuaries, to highlight the types of information that can be obtained from such studies, and to promote the use of paleoenvironmental studies in estuarine management. Readers will learn about the the application of different paleoecological approaches used in estuaries that develop our understanding of their response to natural and human influences. Particular attention is given to the essential steps required for undertaking a paleoecological study, in particular with regard to site selection, core extraction and chronological techniques, followed by the range of indicators that can be used. A series of case studies are discussed in the book to demonstrate how paleoecological studies can be used to address key questions, and to sustainably manage these important coastal environments in the future. This book will appeal to professional scientists interested in estuarine studies and/or paleoenvironmental research, as well as estuarine managers who are interested in the incorporation of paleoenvironmental research into their management programs.
