Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS)

Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS)

Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS) provides the most recent summary of toxicity data relevant to mammals birds reptiles and amphibians and provides values for use in risk assessment applications. Predicting the bioaccumulation of PFAS in terrestrial wildlife (including humans) has proven to be extremely complex. As a group PFAS act differently than traditional non-ionic organic molecules where PFAS can break down and reform whereas some are demonstrated to be extremely persistent. Where sufficient data are provided this book establishes toxicity reference values (TRVs) which are derived to assist in characterizing environmental sources of contamination and making risk-based decisions. Features: Provides toxicity reference values (TRVs) for vertebrates (mammals birds amphibians) for PFAS where sufficient data are available and includes objective supporting background information. Assigns a level of confidence to each TRV to provide the risk assessor with an understanding of the relative uncertainty associated with each value. Presents toxicity data in the formats of scatter diagrams and tables for quick review and assessment. Provides TRVs relevant for screening and decision making This book serves as a useful aid for risk assessors and managers in those industries that have sites contaminated with PFAS consultants tasked with evaluating risks at such sites and staff at regulatory agencies at various governmental levels who need to know how much contamination is considered safe for wildlife. It will also appeal to researchers with an interest in filling the gaps in the current toxicological data for PFAS exposure.

Sustainable Retrofit and Facilities Management

Sustainable Retrofit and Facilities Management

Governments across the globe are setting targets for reducing their carbon emissions. For example the UK Government has committed to an eighty per cent reduction by 2050 when twenty-eight million buildings that currently exist will still be standing; this represents a challenge to improve the energy efficiency of more than one building per minute between now and 2050! This is a problem that needs tackling worldwide and is a challenge to both the refurbishment sector of the global construction industry and to those who own and operate existing buildings. Sustainable Retrofit and Facilities Management provides comprehensive guidance to those involved in the refurbishment and management of existing buildings on minimizing carbon emissions water consumption and waste to landfill along with enhancing the long term sustainability of a building. Practical guidance is provided on measures that can be used to improve the efficiency and sustainability of existing buildings through both good management and refurbishment. Also explored is the relationship between the refurbishment of existing buildings facility management and the wider community infrastructure. The book looks at management tools such as post occupancy evaluation building health checks energy management software green building management toolkits and green leases. Illustrated throughout with case studies and examples of best practice this is a must-have handbook for engineers architects developers contractors and facility managers.

Technologies for Converting Biomass to Useful EnergyCombustion Gasification Pyrolysis Torrefaction and Fermentation

Technologies for Converting Biomass to Useful EnergyCombustion Gasification Pyrolysis Torrefaction and Fermentation

Officially the use of biomass for energy meets only 10-13% of the total global energy demand of 140 000 TWh per year. Still thirty years ago the official figure was zero as only traded biomass was included. While the actual production of biomass is in the range of 270 000 TWh per year most of this is not used for energy purposes and mostly it is not used very efficiently. Therefore there is a need for new methods for converting biomass into refined products like chemicals fuels wood and paper products heat cooling and electric power. Obviously some biomass is also used as food – our primary life necessity. The different types of conversion methods covered in this volume are biogas production bio-ethanol production torrefaction pyrolysis high temperature gasifi cation and combustion. This book covers the suitability of different methods for conversion of different types of biomass. Different versions of the conversion methods are presented – both existing methods and those being developed for the future. System optimization using modeling methods and simulation are analyzed to determine advantages and disadvantages of different solutions. Many international experts have contributed to provide an up-to-date view of the situation all over the world. These global perspectives and the inclusion of so much expertise of distinguished international researchers and professionals make this book unique. This book will prove useful and inspiring to professionals engineers researchers and students as well as to those working for different authorities and organizations.

Compost Utilization In Horticultural Cropping Systems

Compost Utilization In Horticultural Cropping Systems

With the increased interest in and demands for compost from commercial horticultural industries composting is on the verge of becoming an economically feasible option for waste management. While horticultural producers can create some of the compost to meet their own needs demand has grown beyond what they can supply for themselves and others. Compost Utilization in Horticultural Cropping Systems gives you the tools to meet the needs of this growing industry.Consider these statistics:Americans generate about 200 million megagrams of municipal solid waste per yearThe agricultural market for compost could reach over 680 million m3 per yearTwo horticultural areas together account for over 50% of compost use: landscaping (31%) and food crop production (25%)Now consider this:Proven benefits of compost use including plant disease suppression better moisture retention supplying plant nutrients and building soil organic matterIncreased pressure on peat supplies and wider availability of compost productsCreation of composting enterprises by the horticultural industry in response to its own needs rising disposal fees for organic waste and consumer demand for compost at retail centers The first book to establish a composite of the existing scientific knowledge on the use of compost in commercial horticultural enterprises Compost Utilization in Horticultural Cropping Systems gives you a comprehensive review of the production use and economics of compost. It covers production methods compost quality and the parameters associated with its measurement and the biological chemical and physical processes that occur during composting. Rather than searching for information in various places now you can find all the information you need in one convenient source.

Biomass as Energy SourceResources Systems and Applications

Biomass as Energy SourceResources Systems and Applications

Global energy use is approximately 140 000 TWh per year. Interestingly biomass production amounts to approximately 270 000 TWh per year or roughly twice as much whereas the official figure of biomass use for energy applications is 10-13% of the global energy use. This shows that biomass is not a marginal energy resource but more than capable of meeting all our energy and food needs provided it is used efficiently. The use of food in generating energy has been extensively debated but there is actually no need for it given the comprehensive resources available from agriculture and forestry waste. This book discusses the biomass resources available and aspects like efficient energy use. One way of using energy efficiently is to use waste biomass or cellulosic materials in biorefineries where production of fibers and products from fibers is combined with production of most chemicals we need in our daily life. Such products include clothes soap perfume medicines etc. Conventional pulp and paper applications bio-fuel for vehicles and even fuel for aviation as well as heat and power production are covered. The problem with biomass is not availability but the difficulty to use the resources efficiently without harming the long-term productivity. This book covers all types of resources on a global scale making it unique. Many researchers from all over the world have contributed to give a good coverage of all the different international perspectives. This book will provide facts and inspiration to professionals engineers researchers and students as well as to those working for various authorities and organizations.

Vermiculture Technology Earthworms Organic Wastes and Environmental Management

Co-edited by international earthworm expert Clive A. Edwards Vermiculture Technology: Earthworms Organic Wastes and Environmental Management is the first international comprehensive and definitive work on how earthworms and microorganisms interact to break down organic wastes on a commercial basis. Many books cover the importance of composting for reducing the amount of organic wastes in landfills. This reference focuses on innovative vermiculture technology that turns organic waste into a value-added environmentally friendly products that can improve soil fertility and productivity on a large scale. Chronicles more than two decades of growth and changes in earthworm composting technologyBased on the work of an outstanding international cast of scientists the book explores the dramatic growth and changes in vermiculture technology since 1988 and assesses advances made in government-funded projects in the United States and United Kingdom. The contributors discuss outdoor and indoor windrows container systems wedge systems and low labor-requirement fully-automated continuous flow vermicomposting reactor systems that can process more than 1000 tons of organic wastes per reactor per annum. They also highlight the science and biology behind the use and efficacy of vermicomposting examine its importance to developing countries and detail the technology of the past present and future. Although the development of a range of vermicomposting technologies has been rapid and the spread of vermicomposting dramatic the scientific literature remains scattered throughout a range of journals newsletters and online resources. As a compilation of information designed specifically to have an extended shelf life this volume chronicles how vermiculture can be brought into full commercial and industrial development and find application in integrated waste management systems. | Vermiculture Technology Earthworms Organic Wastes and Environmental Management

Software Development Patterns and Antipatterns

Software Development Patterns and Antipatterns

Software development has been a troubling since it first started. There are seven chronic problems that have plagued it from the beginning: Incomplete and ambiguous user requirements that grow by >2% per month. Major cost and schedule overruns for large applications > 35% higher than planned. Low defect removal efficiency (DRE) < 85% on large systems. Cancelled projects that are not completed: > 30% above 10 000 function points. Poor quality and low reliability after the software is delivered: > 5 bugs per FP. Breach of contract litigation against software outsource vendors. Expensive maintenance and enhancement costs after delivery. These are endemic problems for software executives software engineers and software customers but they are not insurmountable. In Software Development Patterns and Antipatterns software engineering and metrics pioneer Capers Jones presents technical solutions for all seven. The solutions involve moving from harmful patterns of software development to effective patterns of software development. The first section of the book examines common software development problems that have been observed in many companies and government agencies. The data on the problems comes from consulting studies breach of contract lawsuits and the literature on major software failures. This section considers the factors involved with cost overruns schedule delays canceled projects poor quality and expensive maintenance after deployment. The second section shows patterns that lead to software success. The data comes from actual companies. The section’s first chapter on Corporate Software Risk Reduction in a Fortune 500 company was based on a major telecom company whose CEO was troubled by repeated software failures. The other chapters in this section deal with methods of achieving excellence as well as measures that can prove excellence to C-level executives and with continuing excellence through the maintenance cycle as well as for software development.
