Life Cycle Assessment of Metals: A Scientific Synthesis
Jul 07, 2014We have assembled extensive information on the cradle-to-gate environmental burdens of 63 metals in their major use forms, and illustrated the interconnectedness of metal production systems. Related cumulative energy use, global warming potential, human health implications and ecosystem damage are estimated by metal life cycle stage (i.e., mining, purification, and refining). For some

Energy Resources Program - USGS
The Energy Resources Program conducts research and assessments to advance the understanding of the Nation’s energy resources. We study processes critical to the formation, accumulation, occurrence and alteration of geologically based energy resources; prepare resource assessments; and evaluate the environmental and socioeconomic effects of energy resource occurrence, production and use.
Mercury - USGS
Year Published: 2019 Chemical and physical controls on mercury source signatures in stream fish from the northeastern United States. Streams in the northeastern U.S. receive mercury (Hg) in varying proportions from atmospheric deposition and legacy point sources, making it difficult to attribute shifts in fish concentrations directly back to changes in Hg source management.

Gold mining - Wikipedia
The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old. A group of German and Georgian archaeologists claims the Sakdrisi site in southern Georgia, dating to the 3rd or
