Book Description
This book introduces key concepts in modeling and risk assessments of vapor intrusion, a process by which the subsurface volatile contaminants migrate into the building of concern. Soil vapor intrusion is the major exposure pathway for building occupants to chemicals from the subsurface, and its risk assessments determine the criteria of volatile contaminants in soil/groundwater in brownfield redevelopment. The chapters feature the recent advances in vapor intrusion studies and practices, including analytical and numerical modeling of vapor intrusion, statistical findings of United States Environmental Protection Agency’s Vapor Intrusion Database and Petroleum Vapor Intrusion Databases, the challenges of preferential pathways, and the application of building pressure cycling methods, and field practices of vapor intrusion risk assessments at developed contaminated sites and in brownfield redevelopment. This volume also summarizes the advantages and limits of current applications in vapor intrusion risk assessment, laying the groundwork for future research of better understanding in risk characterization of soil vapor intrusion using models. Written by experts in this field, Vapor Intrusion Simulations and Risk Assessments will serve as an invaluable reference for researchers, regulators, and practitioners, who are interested in perceiving the basic knowledge and current advances in risk assessments of soil vapor intrusion.

Book Description
Environmental Modeling and Health Risk Analysis (ACTS/RISK) The purpose of this book is to provide the reader with an integrated perspective on several ?elds. First, it discusses the ?elds of environmental modeling in general and multimedia (the term “multimedia” is used throughout the text to indicate that environmental transformation and transport processes are discussed in association with three environmental media: air, groundwater and surface water pathways) environmental transformation and transport processes in particular; it also provides a detailed description of numerous mechanistic models that are used in these ?elds. Second, this book presents a review of the topics of exposure and health risk analysis. The Analytical Contaminant Transport Analysis System (ACTS) and Health RISK Analysis (RISK) software tools are an integral part of the book and provide computational platforms for all the models discussed herein. The most recent versions of these two software tools can be downloaded from the publisher’s web site. The author recommends registering the software on the web download page so that users can receive updates about newer versions of the software.

Book Description
This open access book synthesizes important advances in the assessment and management of soil and groundwater systems contaminated with petroleum hydrocarbons, especially in the form of light non-aqueous phase liquids (LNAPLs). LNAPL characterization and remediation is challenging due to the multi-phase, multi-component nature of the problem and the various physical, chemical, and biological processes involved in a dynamic and heterogeneous hydrogeological setting. This book focuses on the current state of practice of LNAPL characterization and remediation and seeks to provide information and a framework that would allow some of these complexities to be better addressed by contaminated land practitioners, researchers, and regulators.

Book Description
The purpose of risk assessment is to support science-based decisions about how to solve complex societal problems. Indeed, the problems humankind faces in the 21st century have many social, political, and technical complexities. Environmental risk assessment in particular is of increasing importance as health and safety regulations grow and become more complicated. Environmental Risk Assessment: A Toxicological Approach, 2nd Edition looks at various factors relating to exposure and toxicity, human health, and risk. In addition to the original chapters being updated and expanded upon, four new chapters discuss current software and platforms that have recently been developed and provide examples of risk characterizations and scenarios. Features: Introduces the science of risk assessment—past, present, and future Provides environmental sampling data for conducting practice risk assessments Considers how bias and conflict of interest affect science-based decisions in the 21st century Includes fully worked examples, case studies, discussion questions, and suggestions for additional reading Discusses new software and computational platforms that have developed since the first edition Aimed at the next generation of risk assessors and students who need to know more about developing, conducting, and interpreting risk assessments, the book delivers a comprehensive view of the field, complete with sufficient background to enable readers to probe for themselves the science underlying the key issues in environmental risk.

Book Description
Cleaning up known hazards at the 4,700 formerly used defense sites (FUDS) -- sites transferred to other owners before 10/86 -- will require 50+ years and cost $18 billion. This estimate excludes any additional needed cleanup of emerging contaminants -- generally, those not yet governed by a health standard. FUDS cleanup is the responsibility of the U.S. Army Corps of Engineers (Corps). In addition to FUDS, DoD is responsible for cleaning up 21,500 sites on active bases and 5,400 sites on realigned or closed bases. This report examined: (1) the extent to which the Corps reevaluates sites to identify emerging contaminants; (2) how DoD allocates cleanup funds; (3) how the Corps prioritizes FUDS for cleanup; and (4) FUDS program overhead costs.

Book Description
Remediation of subsurface contamination is an up-to-date subject, due to the high number of contaminated sites in all developed countries. Risk assessment for long term exposure to humans is the approach most applied world-wide to identify contaminated sites and the remediation target limits. Exposure pathways for humans at polluted sited often involve inhalation of vapours from soil or groundwater, both outdoor and within enclosed spaces. Many models are available for this purpose, based on concentration input data referred to different media (soil gas, soil, groundwater) located below the ground surface or buildings. This book discusses research in this field in order to improve both modelling tools and field measurements.

An evolving, living organic/inorganic covering, soil is in dynamic equilibrium with the atmosphere above, the biosphere within, and the geology below. It acts as an anchor for roots, a purveyor of water and nutrients, a residence for a vast community of microorganisms and animals, a sanitizer of the environment, and a source of raw materials for co

Book Description
With a weight-of-the-evidence approach, cancer risk assessment indentifies hazards, determines dose-response relationships, and assesses exposure to characterize the true risk. This book focuses on the quantitative methods for conducting chemical cancer risk assessments for solvents, metals, mixtures, and nanoparticles. It links these to the basic toxicology and biology of cancer, along with the impacts on regulatory guidelines and standards. By providing insightful perspective, Cancer Risk Assessment helps researchers develop a discriminate eye when it comes to interpreting data accurately and separating relevant information from erroneous.
