Water pollution problems are of continued importance around the world, with an impact on both populated areas and the environment. This volume consists of papers presented at the 14th International Conference in the series of Monitoring, Modelling and Management of Water Pollution. The environmental problems caused by the increase of pollutant loads discharged into natural water bodies requires the formation of a framework for regulation and control. This framework needs to be based on scientific results that relate pollutant discharge with changes in water quality. The results of these studies allow industry to apply more efficient methods of controlling and treating waste loads, and water authorities to enforce appropriate regulations regarding this matter. Environmental problems are essentially interdisciplinary. Engineers and scientists working in this field must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement, to name but a few. In view of the scarcity of available data, it is important that experiences are shared on an international basis. Thus, a continuous exchange of information between scientists from different countries is essential. Topics covered include: Water contamination; Monitoring, modelling and forecasting; Water management; Wastewater management; Groundwater and aquifers; Flood damage; Freshwater quality; Coastal and offshore pollution; Health risk studies; Agricultural contamination; Industrial pollution; Water reuse; Emerging technologies; Socio-economic-political consequences; Population and climate change; Education and training.

The five volume set LNCS 10960 until 10964 constitutes the refereed proceedings of the 18th International Conference on Computational Science and Its Applications, ICCSA 2018, held in Melbourne, Australia, in July 2018. Apart from the general tracks, ICCSA 2018 also includes 34 international workshops in various areas of computational sciences, ranging from computational science technologies, to specific areas of computational sciences, such as computer graphics and virtual reality.
Ecology is the study of the interrelationships between organisms and their environment, including the biotic and abiotic components. There are at least six kinds of ecology: ecosystem, physiological, behavioural, population, and community. Specific topics include: Acid Deposition, Acid Rain Revisited, Biodiversity, Biocomplexity, Carbon Sequestration in Soils, Coral Reefs, Ecosystem Services, Environmental Justice, Fire Ecology, Floods, Global Climate Change, Hypoxia, and Invasion. This new book presents new research on aquatic ecosystems from around the world.
This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
Waste Management and the Environment VIII contains papers present at the 8th International Conference on Waste Management and the Environment, organised every two years by the Wessex Institute. The contents were contributed by professionals, researchers, government departments and local authorities and cover the current situation of waste management. Waste Management is one of the key problems of modern society due to the ever-expanding volume and complexity of discarded domestic and industrial waste. There is a need to establish better practices and safer solutions for waste disposal. This requires further investigation into disposal methods and recycling, as well as new technologies to monitor waste disposal sites, clean technologies, waste monitoring, public and corporate awareness and general education. Unfortunately many of the policies adopted in the past were aimed at short-term solutions without regard to the long-term implications on health and the environment, leading in many cases to the need to take difficult and expensive remedial action. The development of sustainable strategies is the preferred trend for Waste Management. The approach which has emerged as the most promising has been called 4Rs, where reduction, reuse, recycling and recovery (including the sale of waste as Secondary Raw Materials (SRM) and of Refuse Derived Fuel (RDF)) are seen as the best actions. This largely decreases the volume of waste that needs final disposal. Contents cover such topics as: Environmental impact; Reduce, reuse, recycle and recovery (4Rs); Waste incineration and gasification; Energy from waste; Industrial waste management; Hazardous waste; Agricultural waste; Wastewater; eWaste; Landfill optimisation and mining; Remote sensing; Thermal treatment; Emergent pollutants; Environmental remediation; Direct and indirect pre-treatment of MSW; Disposal of high-level radioactive waste; Legislation; Behavioural issues.
