Title: Selenium fractionation and cycling in the intertidal zone of the Carquinez Strait. Quarterly progress report, January 1996--March 1996

Technical Report ·
DOI:https://doi.org/10.2172/444062· OSTI ID:444062

This quarterly report describes research on selenium (Se) cycling in the marshes and mudflats of the Carquinez Strait between January 1, 1996 and March 31, 1996. Chapter 2 contains descriptions of results of extractions and analyses of sediment cores from the intertidal zone of the Martinez and Benicia field sites, including some x-ray spectroscopy data related to the characterization of the sediment Eh-pH regime. Chapter 3 contains a summary of work in progress on the extraction of various Se species from sediment/soil samples, and efforts in measuring suspended sediment Se. Chapter 4 is an update on stable Se isotope research and Se purification techniques. Chapter 5 describes the rationale, design, and preliminary results of a plant-Se study. Chapter 6 presents the design of a recently initiated sediment dynamics study. The leader is referred to the 1995 Annual Report for details on the project design, site selection, and methodology.
