Results 41 - 50 of 65 listed by similarity [list alphabetically]
Groundwater quality in the San Diego Drainages Hydrogeologic Province, California [More info]
Vanadium and boron were detected at high and moderate concentrations in this area. High concentrations for these constituents were detected almost exclusively in samples collected in the Temecula Valley study area.
PDF 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.
PDF 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.
PDF 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.
PDF Lithium: for harnessing renewable energy [More info]
Explains how this element is used, where we get it, and prospects for future supply and demand.
PDF Manganese: it turns iron into steel (and does so much more) [More info]
Explains how we use this metal, where we get it, and describes the current trends in supply and demand.
PDF Mercury and halogens in coal--Their role in determining mercury emissions from coal combustion [More info]
Explains the complex relationships between coal, mercury, and halogens in light of ongoing efforts to reduce the emission of mercury into the environment.
Mercury Concentrations in Streams Found to Go Through Daily Cycles [More info]
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.
PDF Nickel - Makes stainless steel strong [More info]
Uses, sources, and history of Nickel as a mineral commodity.
PDF Niobium and tantalum: indispensable twins [More info]
Explains why these elements are commonly discussed together, how they are used, where we get them, and prospects for future supply and demand.
