Two saltmarsh locations within Lake Macquarie, NSW, Australia were selected to investigate the uptake and partitioning of metal(loid)s Cu, Zn, As, Se, Cd Pb in Australian halophyte, Sarcocornia quinqueflora associated sub-lethal effects on plant health, including photosynthetic performance, biomass, productivity. Metal(loid)s primarily accumulated roots (BCF > 1). Barriers transport observed at root non-photosynthetic stem transition (TF < 1) for all metal(loid)s, suggesting this species is suitable phytostabilisation. Sediment tissue metal(loid) concentrations significantly correlated with performance biomass. As such, action sediment subsequent effect biomass S.quinqueflora appear be targets molecular analyses further elucidate mechanisms responsible adverse development outcome pathways.
