Erratum for “Trace Metal Accumulation by Estuarine Mollusks”

Metal accumulation kinetics by the estuarine macroalga, Fucusceranoides

The kinetics of Cu, Cd and Pb accumulation by the macroalga, Fucus ceranoides, was studied under simulated estuarine conditions. Accumulation of Cu and Pb proceeded via a pseudo-first-order reaction that was reversible, suggesting desorption or efflux of accumulated metal, with forward rate constants on the order of 0.1 h 1. For both metals, reaction reversibility increased and the equilibrium ...

Assessment of Godavari estuarine mangrove ecosystem through trace metal studies.

Trace metals (Fe, Mn, Cu, Co, Ni. Pb, Cd and Cr) analyses in particulate matter and sediments were carried out at 16 different stations in the Godavari mangrove ecosystem covering the three regions viz., Kakinada (KKD) bay, Goutami-Godavari estuary (GGE) and Coringa and Gaderu mangrove environments (CGME). Higher concentrations of trace metals in particulate matter and in sediments were noticed...

Heavy metal toxicity: Effect on plant growth, biochemical parameters and metal accumulation by Brassica juncea L.

Plant growth, pigment concentration, biochemical parameters and uptake of heavy metals were determined for Brassica juncea L. in response to cadmium and lead stress. The plant exhibited a decline in growth, chlorophyll content and carotenoids with Cd and Pb but Cd was found to be more detrimental than Pb treatment in B. juncea. The protein content was decreased by Cd (900 μM) to 95% and 44% by ...

Trace metal contamination and benthic assemblages in Subaé estuarine system, Brazil.

Accumulation and toxicity of metal oxide nanoparticles in a soft-sediment estuarine amphipod.

Estuarine and marine sediments are a probable end point for many engineered nanoparticles (ENPs) due to enhanced aggregation and sedimentation in marine waters, as well as uptake and deposition by suspension-feeding organisms on the seafloor. Benthic infaunal organisms living in sediments encounter relatively high concentrations of pollutants and may also suffer toxic effects of ENPs. We tested...
