Book excerpt: "The combination of scientific and institutional integrity represented by this book is unusual.

This book was released on 2021 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to diesel emissions causes a range of health effects throughout the body, impairing; respiratory, cardiovascular, central nervous, renal, and cognitive systems. Diesel particulate matter (DPM) in Portland, Oregon is prevalent due to the layout of highly trafficked roadways, rail lines, and marine ports exposing a dense population to high levels of exhaust pollution. These high concentrations of ambient diesel emissions disproportionately impact minority and low-income populations. Ground-based monitoring and modeling are two ways to assess ambient DPM. However, there are uncertainties in modeled DPM due to knowledge gaps in emissions inventories as well as lack of model validation against ground-based measurements. We propose a framework for efficient assessment of localized diesel emission sources, and model validation. Sources of diesel identified as having the largest uncertainty in previous modeling studies were assessed for activity data and emissions were sampled for each main source type. We monitored for a range of traffic related air pollutants such as Black carbon and Nitrogen Oxides in two communities. These measurements will enable us to assess dispersion models, and better characterize DPM sources that are impacting the health of these communities. Fuzzy cluster analysis's applicability in air quality is shown through several studies but not yet for diesel identification. Fuzzy Cluster analysis was investigated as a potential tool for simplified source characterization. We demonstrate its practical use and discuss the opportunities and challenges of interpreting fuzzy clustering output. In summary we present a suite of tools, accessible to most municipalities in the US, that can be used to fill in knowledge gaps or validate models to help communities to better understand and plan to mitigate their health risk from exposure to DPM.

Download or read book Science and Decisions written by National Research Council and published by National Academies Press. This book was released on 2009-03-24 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.

Download or read book Chemical Analysis of Diesel Particulate Matter and an Evaluation of Artifact Formation written by FS-C Lee and published by . This book was released on 1980 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for the sampling and analysis of diesel particulates have been evaluated. A number of different solvents were utilized for the extraction of diesel particulates. Benzo(a)pyrene (BaP) standards spiked on glass-fiber or quartz-fiber filters were found to be oxidized during the sampling of ambient air or exhaust gases. Such degradation was largely reduced by using filters with more inert surfaces, such as Teflon membranes. The results suggest that sample degradation due to gas-BaP reactions requires the presence of a reactive or catalytic medium, such as the glass-fiber filter surface. Such reactions can be minimized with the proper choice of a more inert filter surface such as Teflon. Oxidation of BaP was also observed in diesel extracts during analytical procedures or prolonged storage for several weeks in the dark. The implication of the sampling and analytical artifact problem is a question not only of analytical recovery but also of whether significant biologically active conversion products are produced. Analytical methods to study the extraction efficiency for BaP from diesel particulates are presented. High-performance liquid chromatography (HPLC), high-resolution mass spectrometry (HRMS), and gas chromatography-mass spectrometry (GC-MS) are being investigated for the identification and analysis of these species and preliminary results indicate the presence of a number of oxygenated polynuclear aromatic hydrocarbon (PAH) compounds, which potentially could be produced by oxidation during sampling and analysis.

Download or read book Waste Incineration and Public Health written by National Research Council and published by National Academies Press. This book was released on 2000-10-21 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incineration has been used widely for waste disposal, including household, hazardous, and medical wasteâ€"but there is increasing public concern over the benefits of combusting the waste versus the health risk from pollutants emitted during combustion. Waste Incineration and Public Health informs the emerging debate with the most up-to-date information available on incineration, pollution, and human healthâ€"along with expert conclusions and recommendations for further research and improvement of such areas as risk communication. The committee provides details on: Processes involved in incineration and how contaminants are released. Environmental dynamics of contaminants and routes of human exposure. Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.

Download or read book Assessment of Diesel Particulate Matter DPM Concentrations at a Mechanic Shop written by Amanda T. Peterson and published by . This book was released on 2015 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2012, the World Health Organization's International Agency for Research on Cancer re-classified diesel particulate matter (DPM) as a known carcinogen. DPM is the material exhausted from diesel engines and poses a threat to human health. The purpose of this study was to identify the extent that DPM is present within the mechanic shop facility and while an employee was operating machinery. This research included industrial hygiene sampling, analysis, and evaluation. Although OSHA does not have a current PEL for diesel particulate matter, MSHA enforces the PEL of 160 ug/m3 for DPM. Data was collected on the basis of area monitoring. The three collected GilAir-3 sample analysis results appeared to be in compliance with the MSHA DPM requirements over an eight-hour period. The GASTEC No. 10 Pump with nitrogen oxide and nitrogen dioxide detector tubes appeared to be in compliance with regulations and the detected exposure levels were below the TLV. The TSI Q-Trak concluded based on the ASHRAE 62.1 standard, the ventilation system in the main shop is not incompliance and the maintenance repair bay is incompliance. Although Company XYZ was primarily incompliance with federal regulations, further controls are recommended to reduce potential for exposure to DPM.
