As an integral component of environmental policy, it has become essential to regulate and monitor toxic substances. Past emphasis has been primarily on analytical approaches to the detection of specific, targeted contaminants, thus allowing chemical characterisation. However, toxicity testing or biological assessment is necessary for ecotoxicological evaluation, and this offers marked benefits and advantages that complement chemical analysis.

Key issues to be addressed include identification of pertinent tests, reproducibility and robustness of these tests, and cost considerations.This book examines these issues and describes and explains the approaches that have been developed for environmental toxicity evaluations. Advantages, benefits and drawbacks of the strategies and methods are highlighted.

Directed equally at ecotoxicologists, industrial chemists, analytical chemists and environmental consultants, this book is written in a way that will prove helpful to both new and experienced practitioners.

The demand on land to produce food, for urban development such as housing, industry, shopping areas, infrastructure and also for recreation has increased during the history of mankind. This has resulted in such activities as the reclamation of swamps, flood plains, tidal areas and even lakes by impoldering. Model simulations can be use to gain insight into the system behaviour of different land use and soil composition under temperate humid and humid tropic conditions, The existing package OPOL, based on a non steady model, was further developed to the version OPOL5 for the simulation of hydrological conditions and optimization of the main components of water management systems in polder areas in the temperate humid and humid tropical zone. This model reveals a system's behaviour as well as the effects of variation in the main components of the systems to the overall costs. For example, the designs of pumped drainage systems in polder areas can be optimized by varying the main components until the annual equivalent costs are minimum. A GIS tool has been used to complement OPOL5 for the simulation of the real situation in an area with respect to land use, damage, topography, and soil type. The model package has been applied to two case studies: one in the temperate humid zone, namely the Netherlands and to Thailand in the humid tropical zone.

This volume brings together scholars working in diverse traditions of the humanities in order to offer a comprehensive analysis of the environmental catastrophe as the modern-day apocalypse. Drawing on philosophy, theology, history, literature, art history, psychoanalysis, as well as queer and decolonial theories, the authors included in this book expound the meaning of the climate apocalypse, reveal its presence in our everyday experiences, and examine its impact on our intellectual, imaginative, and moral practices. Importantly, the chapters show that eco-apocalypticism can inform progressively transformative discourses about climate change. In so doing, they demonstrate the fruitfulness of understanding the environmental catastrophe from within an apocalyptic framework, carving a much-needed path between two unsatisfactory approaches to the climate disaster: first, the conservative impulse to preserve the status quo responsible for today's crisis, and second, the reckless acceptance of the destructive effects of climate change. This book will be an invaluable resource for students and scholars interested in the contributions of both apocalypticism and the humanities to contemporary ecological debates.

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications. "

There is an urgent need to develop and improve low cost technologies for wastewater treatment. Simultaneously treating wastewater and producing duckweed in a pond system is, therefore, an attractive solution contributing to both environmental protection and food production. Duckweed has excellent qualities: a high protein content, a high growth rate and is an easy crop to handle. The small plant turns nitrogen from wastewater into a food source. This thesis reports on the effect of different operational variables, like anaerobic pre-treatment, the combination of algae and duckweed ponds and pond depth. Improved nitrogen removal was obtained through the combination of duckweed ponds with algae ponds. Duckweed pond systems could be designed with shallow depth without affecting nitrogen removal efficiency. This research is the result of the cooperative effort between the EIDENAR, Univalle, Cali, Colombia and the UNESCO-IHE Institute for Water Education in Delft, the Netherlands.

Every engineer must eventually face their first daunting design project. Scheduling, organization, budgeting, prototyping: all can be overwhelming in the short time given to complete the project. While there are resources available on project management and the design process, many are focused too narrowly on specific topics or areas of engineering. Practical Engineering Design presents a complete overview of the design project and beyond for any engineering discipline, including sections on how to protect intellectual property rights and suggestions for turning the project into a business. An outgrowth of the editors' broad experience teaching the capstone Engineering Design course, Practical Engineering Design reflects the most pressing and often-repeated questions with a set of guidelines for the entire process. The editors present two sample project reports and presentations in the appendix and refer to them throughout the book, using examples and critiques to demonstrate specific suggestions for improving the quality of writing and presentation. Real-world examples demonstrate how to formulate schedules and budgets, and generous references in each chapter offer direction to more in-depth information. Whether for a co-op assignment or your first project on the job, this is the most comprehensive guide available for deciding where to begin, organizing the team, budgeting time and resources, and, most importantly, completing the project successfully.

The problem with the way the safety industry functions is three-fold: (1) the dysfunctional relationship between business and safety leaders, (2) the practice of Results-Based Safety, and (3) the creation of a false reality. This book presents an insightful and practical approach to how you can move your safety program from Results-Based to Behavior-Based Safety. The move involves understanding what motivates behavior, utilization of consequences, practicing the seven steps of performance coaching, creating accurate safety campaigns, and defining evidence of a healthy Behavior-Based Safety program-this is the other side of safety.. The text: Defines the four major motivations, explains how they work, and how safety leaders can use the right motivation for the right person to help them practice safe behavior Explains how to maximize the impact of reinforcement consequences and minimize punitive consequences in a way that is alingned with an individual's motivation Implements the seven steps of performance coaching conversations, how safety and business leaders can model fluency and frequency to shape behavior to habit strength Provides clearly defined evidence of a healthy Behavior-Based safety program by measuring outcome like locus of control, self-esteem, self-efficacy, and self-actualization Highlights the distinction between Results-Based Safety (RBS) anecdotal practices from the science of Behavior-Based Safety (BBS) methodology Showcases how the distinct difference between a mechanistic and organic culture, and how the four phenomena can be utilized to drive safety culture on purpose Discusses the importance of expanding from lagging indicators to leading indicators for robust metrics and predictability Addresses how the significant negative impact of "telling people what to do" and re-focuses on coaching people on "what to think" The book provides definitions, examples, and applications that focus on how safety and business leaders can influence the behavior of people, impact their culture, and support healthy relationships. It will serve as an ideal text for students, professionals, and researchers in the fields of ergonomics, human factors, human-computer interaction, industrial-organizational psychology, and computer engineering.

Any numerical subsurface model is comprised of three components: a theoretical basis to translate our understanding phenomena into partial differential equations and boundary conditions, a numerical method to approximate these governing equations and implement the boundary conditions, and a computer implementation to generate a generic code for research as well as for practical applications. Computational Subsurface Hydrology: Reactions, Transport, and Fate is organized around these themes. The fundamental processes occurring in subsurface media are rigorously integrated into governing equations using the Reynolds transport theorem and interactions of these processes with the surrounding media are sophisticatedly cast into various types of boundary conditions using physical reasoning. A variety of numerical methods to deal with reactive chemical transport are covered in Computational Subsurface Hydrology: Reactions, Transport, and Fate with a particular emphasis on the adaptive local grid refinement and peak capture using the Lagrangian-Eulerian approach. The topics on coupled fluid flows and reactive chemical transport are unique contributions of this book. They serve as a reference for research as well as for practical applications with a computer code that can be purchased from the author. Four computer codes to simulate vertically integrated horizontal solute transport (LEMA), contaminant transport in moving phreatic aquifers in three dimensions (3DLEMA), solute transport in variably saturated flows in two dimensions (LEWASTE), and solute transport under variably saturated flows in three dimensions (3DLEWASTE) are covered. These four computer codes are designed for generic applications to both research and practical problems. They could be used to simulate most of the practical, real-world field problems. Reactive chemical transport and its coupling with fluid flows are unique features in this book. Theories, numerical implementations, and example problems of coupled reactive transport and flows in variably saturated media are presented. A generic computer code, HYDROGEOCHEM 3.0, is developed. A total of eight example problems are used to illustrate the application of the computational model. These problems are intended to serve as examples for setting up a variety of simulations that one may encounter in research and field-site applications. Computational Subsurface Hydrology: Reactions, Transport, and Fate offers practicing engineers and scientists a theoretical background, numerical methods, and computer codes for modeling contaminant transport in subsurface media. It also serves as a textbook for senior and graduate course on reactive chemical transport in subsurface media in disciplines such as civil and environmental engineering, agricultural engineering, geosciences, soil sciences, and chemical engineering. Computational Subsurface Hydrology: Reactions, Transport, and Fate presents a systematic derivation of governing equations and boundary conditions of subsurface contaminant transport as well as reaction-based geochemical and biochemical processes. It discusses a variety of numerical methods for moving sharp-front problems, expounds detail procedures of constructing Lagrangian-Eulerian finite element methods, and describes precise implementation of computer codes as they are applied to subsurface contaminant transport and biogeochemical reactions.

The contributions include recent investigations into anisotropy and non-linearity, the effects of stress-strain-time history, ageing and time effects, yielding, failure and flow, cyclic and dynamic behaviour. In addition, advanced geotechnical testing is applied to real engineering problems, and to ways of synthesising information from a range of sources while engaging in practical site characterisation studies.

At the time of European discovery, the ancient North American forests stretched across nearly half the continent. And while today little remains of this past glory, efforts are underway to bring back some of the diverse ecosystems of that era. America's Ancient Forests: From the Ice Age to the Age of Discovery provides scientists and professionals with essential information for forest restoration and conservation projects, while presenting a compelling and far-reaching account of how the North American landscape has evolved over the past 18,000 years.

The book weaves historical accounts and scientific knowledge into a dynamic narrative about the ancient forests and the events that shaped them. Divided into two major parts, it covers first the glaciers and forests of the Ice Age and the influences of native peoples, and then provides an in-depth look at these majestic forests through the eyes of the first European explorers. Changes in climate and elevation, the movement of trees northward, the assembly of modern forests, and qualities that all ancient forests shared are also thoroughly examined.

A special feature of this book is its self-contained introduction to the early history of Native American peoples and their environment. The author draws on his roots in the Osage nation as well as painstaking research through the historical record, offering a complete discussion of how the cultural practices of hunting, agriculture, and fire helped form the ancient forests.

This book was written to give energy-involved professionals the tools they need to take their energy audits to the next level, and use them to accurately predict a building's future energy use and true savings potential. Going beyond the conventional energy audit, which can lead to projections which are frequently off by as much as 20%, this book provides detailed guidelines on how to use the new tool, the investment grade audit (IGA), which enables prediction of savings with much greater accuracy. Building on the traditional audit, the IGA requires the addition of a "risk assessment component" which evaluates conditions in a specific building and/or process and reduces the level of uncertainty as to how proposed energy efficiency measures will really behave over time. The authors have covered every aspect of the IGA, including risk management, the "people" factor, measurement and verification, financing issues, report presentation guidelines, and master planning strategies.
