Uptake and distribution of metals in two dominant salt marsh macrophytes, Spartina alterniflora (cordgrass) and Phragmites australis (common reed)

We examined patterns of biomass accumulation and tissue concentrations of five metals—mercury, copper, zinc, chromium, lead—and two elements—carbon and nitrogen—to determine differences in net metal accumulation and distribution between Phragmites australis (common reed) and Spartina alterniflora (c...

Description
Summary:We examined patterns of biomass accumulation and tissue concentrations of five metals—mercury, copper, zinc, chromium, lead—and two elements—carbon and nitrogen—to determine differences in net metal accumulation and distribution between Phragmites australis (common reed) and Spartina alterniflora (cord grass) which were growing intermingled in a contaminated low marsh. Data were collected at 2-month intervals across a growing season (April–October, 1999). Although they comprise only 5–15% of whole plant biomass for both species, roots consistently contained 70–100% of the whole plant metal burdens for both S. alterniflora and P. australis (shoot:root ratio
