Explains the complex relationships between coal, mercury, and halogens in light of ongoing efforts to reduce the emission of mercury into the environment.
Research findings and examples of application to real problems--highly variable conditions cause the production of toxic methyl mercury in the environment which accumulates in fish.
Collection of six short papers related to the mercury geochemical society, the study of mercury in coal, concentrations in sediment, soil, water, and fish collected near mercury and gold mines, and volanic emissions of mercury.
Explains sources of mercury in the air, ways in which mercury is concentrated in animals, and describes how we measure deposition of atmospheric mercury, with summaries of observations.
Reviews how coal fires occur, how they can be detected by airborne and remote surveys, and, most importantly, the impact coal-fire emissions may have on the environment and human health, especially mercury, carbon dioxide, carbon monoxide, and methane.
What happens to all the scrap metal? How well does recycling work? This guide explains what we know about the overall processes of recycling various metals.
Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
