摘要：

This work describes the rationale used to substantiate the reliability and reproducibility of results obtained from a sequential extraction procedure employed to determine trace metals in restored marsh sediments originating from Calcasieu River ship channel dredge spoils in southwestern Louisiana. The determination was conducted using flame and graphite furnace atomic absorption spectrometry. Metals determined were Cr, Cu, Fe, Mn, Ni, Pb, and Zn. The variations in concentrations between replicate samples and duplicate samples were not statistically significant. Concentrations of all trace metals studied were in agreement with previous studies. (C) 1998 Academic Press.
