Chemical elements and element groups
Groundwater quality in the north San Francisco Bay groundwater basins, California [ More info] Summary of chemical constituents of ground water that are of concern to human activity in this area. Arsenic is the constituent that occurs most frequently in high concentrations.
Indium: bringing liquid-crystal displays into focus [ More info] Explains the uses for, sources of, and supply and demand for this rare metal element.
Investigating atmospheric mercury with the U.S. Geological Survey mobile mercury laboratory [ More info] 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.
Lead Poisoning in Wild Birds [ More info] Even though lead usage has declined due to environmental awareness and regulation, several human sources of lead continue to affect birds. Hunting ammunition and fishing gear are ingested by the birds, with toxic effects.
Lead-Soft and easy to cast [ More info] Explains how we use lead, where it comes from, and how we might ensure that we have adequate supplies of this mineral commodity in the future.
Lithium: for harnessing renewable energy [ More info] Explains how this element is used, where we get it, and prospects for future supply and demand.
