This article is the first part of a study dealing with current and prospective clean coal technologies. For this purpose, the importance of coal utilization in electricity production and the importance of clean coal technologies (CCTs) for the minimization of the environmental impacts of coal-fired power generation are discussed as an introduction to the subject. The article includes an extensive presentation about the source and formation mechanisms of the major pollutants and their control strategies.

Stream-bed sediment for the size fraction less than 150 μm, examined in 14,000 samples collected mostly from minor tributaries to the major rivers throughout the Mississippi River drainage system, is composed of 5 mineral fractions identified by factor analysis—Al-silicate minerals, quartz, calcite and dolomite, heavy minerals, and an Fe–Mn fraction. The Al-silicate fraction parallels its distribution in the regolith, emphasizing the local sediment source as a primary control to its distribution. Quartz and the heavy-mineral fraction, and associated trace elements, exhibit a complementary distribution to that of the Al-silicate fraction, with a level of enrichment in the bed sediment that is achieved through winnowing...

Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed the Sediment-Bound Contaminant Resiliency and Response (SCoRR) strategy to define baseline and post-event sediment-bound environmental health (EH) stressors. These data document the major element chemistry, major and trace chemical composition, total sulfur content, inorganic and organic carbon for soil and sediment samples from selected stations...
