Book excerpt: Book & CD. Coal mine dust is one of the most serious occupational hazards in the coal mining industry, and overexposure can cause coal workers' pneumoconiosis (CWP) and a number of other lung diseases, collectively referred to a black lung disease. CWP has been the underlying or contributing cause of death for more than 75,000 coal miners since 1968. This book provides an overview of key studies, background history and health reviews on occupational exposure to respirable coal mine dust.

Available in PDF, EPUB and Kindle. Book excerpt: Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

Available in PDF, EPUB and Kindle. Book excerpt: This book, Environmental Health Risk - Hazardous Factors to Living Species, is intended to provide a set of practical discussions and relevant tools for making risky decisions that require actions to reduce environmental health risk against environmental factors that may adversely impact human health or ecological balances. We aimed to compile information from diverse sources into a single volume to give some real examples extending concepts of those hazardous factors to living species that may stimulate new research ideas and trends in the relevant fields.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal was, is, and will be one of the major energy sources for our society. Coal mining activities, from extraction to utilization, intrinsically produce coal dust and its associated aerosols, which are known to be safety and health hazards. Within the mine dust aerosols, the exposure of the respirable crystalline silica (RCS) dust is the most toxic component for the coal workers. Excessive RCS exposure can potentially cause the development of disabling and irreversible lung disease which is known as silicosis. The silicosis cases and its related mortality trend are still high in the United States, and the recent resurgence of coal miners' lung disease sends an alarming sign for the industry. Characterization of the physiochemical properties of RCS is the prerequisite for the improved understanding of its toxicity and adverse effects on miners' respiratory system. In this study, the mineral composition of respirable coal mine dust (RCMD), and type (s) of crystalline silica with its varying degrees of crystallinity in the mine dust were investigated. For this purpose, samples were collected from the top of coal (ToC) and bottom of coal (BoC) rock strata, which are believed to have the highest amount of crystalline silica. In addition, we also collected rock samples from both the roof and pillar of a limestone mine in Pennsylvania to define its crystalline components for potential silica characterization. After preparing the lab-generated respirable dust using a cryomill, the X-ray diffraction (XRD) technique in combination with JADE software was employed to identify the mineral phases and determine the quantitative mineral composition. The results from the quantitative analysis revealed that quartz (crystalline silica), muscovite, kaolinite, and clinochlore are the most abundant minerals in the ToC and BoC strata. The average amount of crystalline silica (quartz) was assessed to be 25% in the ToC and 17.3% in the BoC samples from the Lower Freeport coal seam. The quartz content in the samples from the ToC strata of Lower Kittanning was found to be 16.5%. Furthermore, phase identification analyses determined that, among the quartz types, alpha quartz ([alpha]-quartz) is the only type that exists in the samples. The quantitative analysis also reported a considerable amount of amorphous content for all samples. The amorphous content associated with the samples from near the coal seam comparatively showed a higher quantity, suggesting that the coal-ToC and coal-BoC interfaces contain a significant amount of amorphous. The quantitative analyses of limestone samples reported high calcite and dolomite with negligible quartz content. The amount of quartz in the sample from the pillar of the limestone mine was 0.22%, whereas no quartz was reported for the sample from the roof of the same mine. According to the results, it is advisable to conduct additional elemental analysis to verify the mineral composition of the samples. Additionally, it is recommended to undertake comprehensive investigations into the mineralogy and toxicity of the amorphous content found in coal mine dust, especially those originating from the interfaces of coal and rock strata.

Available in PDF, EPUB and Kindle. Book excerpt: Trace Elements in Coal focuses on the compositions, reactions, and properties of trace elements in coal. The book first discusses the origin of trace elements in coal. The formation of peat; geological and geochemical aspects of coal seams; geology of Australian coals; constitution of coal; history of trace elements in coal; and coal mining in Australia are discussed. The text also clarifies the mode of occurrence of trace elements in coal. The identification of minerals in coal; silicon-rich minerals; carbonate minerals; sulfide minerals; lignites and brown coals; and phosphates are discussed. The book then underscores the methods of analysis. Inductively coupled plasma atomic emission spectrometry; atomic absorption spectrometry; spark source mass spectrometry; and neuron activation analysis are described. The text also focuses on the contents of trace elements in coal; comparisons of coal with shale and soil; relationship of radioactivity and coal; and relevance of trace elements in coal. The book is a good source of data for readers wanting to study the trace elements in coal.
