Accumulation of humic acid in DET/DGT gels
(American Chemical Society, 2010)
Gel layer based sensors are increasingly employed for dynamic trace metal speciation analysis in aquatic and soil media. In DGT (Diffusive Gradient in Thin film), polyacrylamide hydrogels are commonly used for the diffusive ...
Stress and toxicity of biologically important transition metals (Co, Ni, Cu and Zn) on phytoplankton in a tropical freshwater system: An investigation with pigment analysis by HPLC
(Elsevier, 2010)
Stress and toxicity of four biologically important transition metals (Co, Ni, Cu and Zn) on phytoplankton in Godavari River (a tropical freshwater system) were studied to understand the fate of phytoplankton of freshwater ...
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 ...
Linkage between speciation of Cd in mangrove sediment and its bioaccumulation in total soft tissue of oyster from the west coast of India
(Elsevier, 2016)
This study established a mechanistic linkage between Cd speciation and bioavailability in mangrove system from the west coast of India. High bioaccumulation of Cd was found in the oyster (Crassostrea sp.) even at low Cd ...
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 ...
Mercury speciation in coastal sediments from the central east coast of India by modified BCR method.
(Elsevier, 2014)
This is the first study to describe distribution and speciation of Hg in coastal sediments from the central east coast of India. The concentrations of Hg in the studied sediments were found to be much lower than the Hg ...
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 ...
Intra-annual variations of arsenic totals and species in tropical estuary surface sediments
(Elsevier, 2012)
Arsenic totals and species were found to vary during a one year period in the surface sediments of Godavari estuary (the third largest river in India). This study suggests that increasing salinity of overlying water column ...
Partitioning of metals in different binding phases of tropical estuarine sediments: importance of metal chemistry
(Springer, 2016)
Distribution of metals in different binding phases of estuarine sediments provides chemically significant description of metal–sediment interactions. This study describes the influences of ligand field stabilization energy ...
