Selenium fractionation and cycling in the intertidal zone of the Carquinez Strait. Quarterly progress report, October 1995--December 1995

PDF Version Also Available for Download.

Description

This quarterly report describes the research on selenium (Se) cycling in the marshes and mudflats of the Carquinez Strait between October 1, 1995 and December 31, 1995. Chapter 2 contains descriptions of field activities and laboratory work related to chemical characterization of sediments and soils. Eh and pH data are presented. 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 describes advances made in the analysis of parts-per-trillion level Se, using a lanthanum hydroxide co-precipitation method, and the determination of matrix ... continued below
