Trichloroethylene (TCE) is a solvent that is used as a degreasing agent, a chemical intermediate in refrigerant manufacture, and a component of spot removers and adhesives. It is produced in mass quantities but creates dangerous vapors and is an environmental contaminant at many industrial and government facilities, including facilities run by the U.S. Department of Defense (DoD). It is important to determine the safe occupational exposure level (OEL) for the solvent in order to protect the health of workers who are exposed to its vapors. However, there are concerns that the current occupational standards insufficiently protect workers from these health threats. Review of DOD's Approach to Deriving an Occupational Exposure Level for Trichloroethylene makes recommendations to improve the DoD's approach to developing an OEL for TCE, strengthen transparency of the process, and improve confidence in the final OEL value. This report reviews the DoD's approach using a literature review, evidence synthesis based on weight of evidence [WOE], point-of-departure derivation, physiologically based pharmacokinetic modeling, extrapolation tools, and explores other elements of the process of deriving an OEL for TCE. It examines scientific approaches to developing exposure values and cancer risk levels, defining the scope of the problem, and improving hazard identification.

Download and read online ebook Traffic-Related Air Pollution write by Haneen Khreis. This book was released on 2020-08-20. Traffic-Related Air Pollution available in PDF, EPUB and Kindle. Traffic-Related Air Pollution synthesizes and maps TRAP and its impact on human health at the individual and population level. The book analyzes mitigating standards and regulations with a focus on cities. It provides the methods and tools for assessing and quantifying the associated road traffic emissions, air pollution, exposure and population-based health impacts, while also illuminating the mechanisms underlying health impacts through clinical and toxicological research. Real-world implications are set alongside policy options, emerging technologies and best practices. Finally, the book recommends ways to influence discourse and policy to better account for the health impacts of TRAP and its societal costs. Overviews existing and emerging tools to assess TRAP’s public health impacts Examines TRAP’s health effects at the population level Explores the latest technologies and policies--alongside their potential effectiveness and adverse consequences--for mitigating TRAP Guides on how methods and tools can leverage teaching, practice and policymaking to ameliorate TRAP and its effects

Download and read online ebook Approaches to Research in Child and Youth Care write by Priscilla Bengo. This book was released on 2024-07-12. Approaches to Research in Child and Youth Care available in PDF, EPUB and Kindle. Approaches to Research in Child and Youth Care in Canada is a fundamental text for child and youth care programs with the aim of making research methods more approachable to students. Priscilla Bengo breaks down foundational research methods in an accessible way and explores the roles of objectivity and logic in sound decision making in child and youth care practices. Opening with the core functions of scientific inquiry in the field, Bengo introduces students to the ethical, political, and cultural contexts of child and youth care research and provides the tools to become a culturally competent researcher. Students will gain a thorough understanding of problem formulation, measurement, and data collection methods for large data sources, and how to work with both qualitative and quantitative data. Grounded with practical examples and exercises throughout, Approaches to Research in Child and Youth Care in Canada is a must-read for research methods courses in child and youth care programs that will build integral research skills for students in child and youth care, social work, and the programs focused on the helping professions.

This book was released on 1994. A Retrospective Quantitative Assessment of Trichloroethylene Exposure of Workers at Aircraft Maintenance Facilities at Hill Air Force Base Through the Use of Modeling available in PDF, EPUB and Kindle. Monte Carlo simulation and source-receptor modeling are used to estimate the TCE exposures encountered by select workers at aircraft maintenance facilities at Hill Air Force Base between 1955 and 1979. An epidemiological study of this group, a retrospective cohort study of 14,457 workers who were employed at the base for a minimum of one year between 1952 and 1956, was headed by Dr. R. Spirtas of the National Cancer Institute to evaluate mortality associated with occupational exposure. One of the major conclusions of the study was that TCE 'probably does not pose a strong carcinogenic risk for man.' In the Spirtas study, historic exposure levels were not quantitatively estimated. Instead, indices of exposure to TCE were assigned to reflect relative differences in exposure levels. It is the objective of this research effort to quantitatively estimate specific worker exposures, thus adding to the weight of evidence necessary to classify TCE as a human carcinogen or otherwise.
