PDF Corals as climate recorders [More info]
Shows how coral reef specimens are collected, the type of information gained from them, and the methods by which they are measured and studied to understand recent (past few centuries) changes in climate.
PDF Emissions from Coal Fires and Their Impact on the Environment [More info]
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.
PDF Gallium--A smart metal [More info]
Usefulness and characteristics of this mineral commodity.
Geologic studies of mercury [More info]
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.
Groundwater quality in Coachella Valley, California [More info]
Five trace elements with human-health concerns were detected at high concentrations: arsenic, boron, fluoride, molybdenum, and strontium. Vanadium was present at moderate concentrations.
Groundwater quality in the Antelope Valley, California [More info]
Trace elements were present at high concentrations in 32% of the primary aquifers here, and at moderate concentrations in 17%. Of particular interest are aluminum, arsenic, vanadium, boron, fluoride, chromium, lead, and molybdenum.
