Geochemical partitioning of Cu and Ni in mangrove sediments: Relationships with their bioavailability
(Elsevier, 2015)
Sequential extraction study was performed to determine the concentrations of non-residual metal-complexes in the mangrove sediments from the Divar Island, (west coast of India). Accumulation of metal in the mangrove roots ...
Understanding our seas: National Institute of Oceanography, Goa
(Current Science Association, 2015)
The present article summarizes the research done at the CSIR–National Institute of Oceanography in 2014 in ocean science, resources and technology. Significant research has been conducted on air–sea interactions and coastal ...
Lead distribution in coastal and estuarine sediments around India
(Elsevier, 2015)
This study describes the geochemical distribution of lead (Pb) and identifies the critical factors that significantly control Pb distribution and speciation in coastal and estuarine sediments around India by using published ...
Relationship between the lability of sediment-bound Cd and its bioaccumulation in edible oyster.
(Elsevier, 2015)
A linkage between Cd speciation in sediments and its bioaccumulation in edible oyster (Crassostrea sp.) from a tropical estuarine system was established. Bioaccumulation of Cd in edible oyster increased with the increasing ...
Reduction of mercury (II) by humic substances-influence of pH, salinity of aquatic system
(Springer, 2015)
This study demonstrates that under abiotic dark conditions in aquatic system, humic substances are not only capable of converting Hg(II) to Hg<sup>0</sup> but also able to bind Hg(II) ion. The degree of Hg(II) reduction ...
Relationship between the lability of sediment-bound Cd and its bioaccumulation in edible oyster
(Elsevier, 2015)
A linkage between Cd speciation in sediments and its bioaccumulation in edible oyster (Crassostrea sp.) from a tropical estuarine system was established. Bioaccumulation of Cd in edible oyster increased with the increasing ...
Chemical characterization of meltwater from East Rathong glacier vis-a-vis Western Himalayan glaciers
(Springer, 2015)
Ice and meltwater samples from Rathong glacier and its pro-glacial stream Rathong chu, were collected during late winter season. Samples were analyzed to study the chemical composition , weathering, and geochemical processes ...
Organic matter - A key factor in controlling mercury distribution in estuarine sediment
(Elsevier, 2015)
Organic matter (OM) was found to play an important role in controlling mercury (Hg) distribution and speciation in estuarine sediment of the Vembanad Lake. The sedimentary organic carbon (OC) from the northern part of the ...
Environmental controls on the speciation and distribution of mercury in surface sediments of a tropical estuary, India
(Elsevier, 2015)
Distribution and speciation of mercury (Hg) in the sediments from a tropical estuary (Godavari estuary) was influenced by the changing physico-chemical parameters of the overlying water column. The sediments from the ...
