Diffuse Pollution '98


Book Description

Diffuse Pollution of surface, coastal and ground waters is a major environmental and economic problem in the world today. Unlike point source pollution, which has to some extent been controlled by developments in technology and regulation, diffuse pollution is difficult to control, requiring the application of technological and socio-economical approaches and of education. The 46 papers in these proceedings have been selected from those presented at the 3rd International Conference on Diffuse Pollution, which addressed urban and rural diffuse pollution problems and solutions as experienced in several countries. The papers are divided into five themes: Identification of sources and loads Best Management Practices Receiving water impacts Modelling diffuse pollution Watershed management. The proceedings conclude with two papers, prepared by prominent specialists, that summarise the key findings at the conference. These proceedings will prove an essential resource for all concerned, whether as researchers, regulators or practioners, with diffuse pollution and its control.




Contaminated Soil '98


Book Description

These conference proceedings provide over 300 international papers on contaminated soil, focusing on policies, research development, regulations, practical implementations and experiences related to contaminated sites.




Diffuse Pollution


Book Description

Diffuse (non-point source) pollution is increasingly being recognised as a major source of water quality problems in both surface and ground water. Indeed, as pollution resulting from point sources is reduced by the efforts of regulators, diffuse sources frequently remain as the dominant source of pollution. The book is an introductory text covering the nature, causes and the significance of diffuse pollution of both urban and rural origin. Best management practices to tackle the problems are examined as are the ways in which the adoption of such practices may be brought about. Use is made of case studies from several countries to examine the strengths and weaknesses of various approaches. Diffuse Pollution covers both urban and rural sources. Urban sources include run-off from impermeable surfaces of roads, industrial areas and housing which may be contaminated by hydrocarbons, heavy metals, organic chemicals and other undesirable substances. Rural sources include water containing pollutants arising from agriculture and forestry such as plant nutrients, pesticides, microbes and soil itself. This concise book will prove useful to practitioners in the field of pollution control both in an urban and a rural environment, to regulators, to researchers new to the field, and to academics and students. An extensive reference section aids the reader in exploring the subject further.

Wetland Systems for Water Pollution Control 1998


Book Description

Proceedings of the International Conference on Wetland Systems for Water Pollution Control, held in Brazil, 27 September - 2 October 1998. It is increasingly recognised that wetland systems can play a significant role in protection of the water environment. Where once their main attraction was a perceived 'green' character, now constructed wetlands are chosen to provide cost-effective and efficient wastewater treatment - in municipal and industrial applications - that matches up to regulatory requirements. The forty-five papers in these proceedings have been selected from those presented at the highly successful 6th International Conference on Wetland Systems for Water Pollution Control. Six papers are invited keynote addresses, which review aspects of wetland systems from an authoritative and up-to-date perspective. The remaining papers are divided into the following themes: Industrial Wastewaters; Ecology of Microorganisms and Natural Systems; Wetland Processes; Combined Systems; Role of Plants; Design of Wetlands; Wetland Hydraulics; Hospital Wastewaters; and Stormwater and Runoff.

Environment and Development


Book Description

Environment and Development: Basic Principles, Human Activities, and Environmental Implications focuses on the adverse impact that human activities, developments, and economic growth have on both natural and inhabited environments. The book presents the associated problems, along with solutions that can be used to achieve a harmonic, sustainable development that provides for the co-existence of man and natural life. Chapters provide detailed information on a range of environments including: atmospheric, aquatic, soil, natural, urban, energy, and extraterrestrial, as well as the relationship between the environment and development. In addition, this comprehensive book presents the latest research findings and trends in global environmental policy for each issue. - Offers a discussion of the extraterrestrial environment and waste in earth orbit as one of the distinctive topics of the book - Addresses global environmental policy issues and policies - Presents tabulated data to support the analysis and explain the issues presented - Includes case studies covering many topics of current interest - Analyzes environmental issues and proposes solutions grounded in recent research findings - Discusses the various interpretations of the development concept as well as alternative pathways to sustainable development




Soil pollution: a hidden reality


Book Description

This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.




Vertical Flow Constructed Wetlands


Book Description

Vertical flow constructed wetlands for wastewater and sludge treatment represent a relatively new and still growing technology. Vertical Flow Constructed Wetlands is the first book to present the state-of-the-art knowledge regarding vertical flow constructed wetlands theory and applications. In this book, you will learn about vertical flow systems with information about application and performance. Vertical Flow Constructed Wetlands also includes information on how different countries are applying the technology, with design guidelines to illustrate best practices worldwide. A focus on water conservation through reuse of treated water showcases the benefit of vertical flow construction, which has greatly increased the attractiveness of the technology in recent years. - All state-of-the-art knowledge regarding vertical flow constructed wetlands gathered in one book - A review of various constructed wetland approaches, including information about applications and performance, helps clarify what is currently known about constructed wetland principles and design - Discussion of how to manage the treated wastewater leaving the vertical flow for increasing biodiversity, providing food and habitat for birds, and producing harvestable biomass or crops - Includes case studies of constructed wetlands in developing countries




WHO Guidelines for Indoor Air Quality


Book Description

This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.
