Research Chemistry

Project Objectives

Many projects within the Geologic and Biologic Resources Disciplines use chemical analyses as a tool in the study of various earth, ecological, and biological processes and features. Often, the success of these projects is dependent upon the availability of modern, rapid, multi-element analytical instruments and techniques that are beyond the scope and capability of most individual projects. The Research Chemistry Project provided access to state-of-the-art chemical analysis hardware and software, as well as the expertise of highly experienced research scientists to help solve unusually difficult problems in the field of analytical geochemistry that could not be addressed by the routine methods of even the best commercial laboratories. Techniques supported included ultra-trace analyses (sub-ppb concentrations) of both solid and liquid samples for virtually every element in the periodic chart, as well as the quantitative determination of specific chemical species (e.g. As(III), As(V), metal cyanide complexes) and mode of occurrence of elements in minerals. These methods permitted the USGS to participate in a broad spectrum of scientific studies ranging from petrology and mineralogy to ecology and geo-environmental issues. Long term efforts of this project included the development of new standard reference materials that are used by USGS analytical labs and projects to assure the highest analytical accuracy possible; in addition, these standards were used by more than 20 countries to monitor the quality of geochemical data produced by laboratories from around the globe.

The objectives of the Research Chemistry Project were fivefold:

  1. develop new and emerging geoanalytical techniques that the Geologic Discipline would need within the next 5 years,
  2. maintain geochemical analysis instrumentation, laboratories, and techniques for use by other projects,
  3. provide training and oversight to other scientists in the use of geoanalytical hardware and software,
  4. develop new geological standard reference materials that were used by scientists to calibrate analytical instruments and monitor laboratory performance, and
  5. maintain specialized in-house chemical analysis capabilities for use in the characterization of new reference materials, and for use with outside funded projects on difficult-to-analyze sample matrices that are beyond the capabilities of the contract laboratory.

Relevance & Impact

The primary goal of this project was the continued development of new, state-of-the-art geoanalytical tools for application to topical studies in geology, climate history, mineralogy, ecology, and biology. Therefore, the impact of this project was highly significant to integrated science activities across the USGS.

This project participated in NOAA-sponsored sediment round-robin exercises for the past 9 years. Our geochemistry laboratories have consistently achieved high scores for both precision and accuracy, and have been the highest rated laboratory out of 30 internationally recognized geochemistry laboratories. (Ref: Willie, S., 2003, Sixteenth round intercomparison for trace metals in marine sediments and biological tissues: Prepared for the Coastal Monitoring and Bioeffects Division Office of Ocean Resources Conservations and Assessment, National Oceanic and Atmospheric Administration).

Several projects within the Mineral Resources Program utilized the sequential extraction techniques that have been developed in this project for the determination of mode-of-occurrence of constituents. This technique provided information on current and potential availability and mobility of chemical elements, especially those with possible ecosystem health effects such as arsenic (As). It was applied to studies in (1) the Fairbanks As in drinking water project, (2) Warrior Basin As Project, looking at the residence of As in sediments related to coal and Au mining in the basin, (3) Alaskan biogeochemical studies looking at Cd and other trace element mobilities in mineralized and un-mineralized areas, and (4) Bangladesh As studies, looking at the mode of occurrence of As in sediments to assess sources of high As in drinking water wells.
