Creator:: Liu, Yan
Abstract:: An automated on-line ion exchange trace enrichment system has been developed to improve the detection limits of flame atomic absorption (AA) spectrophotometry in the determination of trace metals in natural waters. The sample solution is passed through a column of Chelex-100 chelating resin by a carrier buffer stream delivered from...

Creator:: Pequegnat, John Eugene
Abstract:: Short-term changes in the distribution, surface to 10 meters, of phytoplankton-associated trace metals (Fe, Mn, Cr, Zn, Co, Ni, and Cu) were studied in the near-shore waters off Humboldt Bay, California, through the summer of 1971. The depth distribution of phytoplankton-associated trace metals was related to local hydrography. During periods...

Creator:: Ambrose, Arthur Sigurd
Abstract:: An on-line trace enrichment (TE) system, based on high pressure liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has been developed for trace metal analysis. The sample is pumped through a column filled with a cation exchange resin which traps metal ions. The ions are subsequently stripped from the column...

Full Text:: Hydrospheric Trace Elements and Thei r Application in Tracing Water

Creator:: Rinella, Frank A., Geological Survey (U.S.), United States. Forest Service, and Douglas County (Or.)
Abstract:: This report presents the concentrations of major ions, nutrients, and trace elements in water and bottom sediments collected in the four-tributaries during the low-flow condition of September 9-13, 1996. Stream-water chemistry results are contrasted, and trace-element concentrations compared with U.S. Environmental Protection Agency chronic aquatic life toxicity criteria. Bottom -sediment...
Resource Type:: Technical Report

Creator:: Flannery, Kelly M.
Abstract:: Many trace elements (e.g., Zn, Cd, Mo) are essential phytoplankton micronutrients, making them crucial to the marine ecosystem and ultimately the carbon cycle. Because of this association trace metals are also utilized in paleoceanographic studies (e.g., Mo, Cd). However, not much is known about what controls the cycling of these...
