An insight into mercury reduction process by humic substances in aqueous medium under dark condition
(Springer, 2017)
Mercury (Hg) reduction by humic substances (HS) in the aquatic medium under the dark condition is a poorly understood but important process in Hg biogeochemical cycling. In this study, an effort was made to provide a better ...
Impact of salinity and pH on phytoplankton communities in a tropical freshwater system: An investigation with pigment analysis by HPLC
(The Royal Society of Chemistry, 2011)
An in vitro study was carried out to understand the effects of salinity shock and variation in pH on phytoplankton communities in a tropical freshwater system of the Godavari River (a major peninsular river in India). The ...
Changes in metal contamination levels in estuarine sediments around India – An assessment
(Elsevier, 2014)
This review is the first attempt to comprehend the changes in metal contamination levels in surface estuarine sediments with changing time around India. Contamination factor, geoaccumulation index, pollution load index, ...
Kinetic speciation and bioavailability of copper and nickel in mangrove sediments
(Elsevier, 2014)
An attempt was made to establish a mechanistic linkage between chemical speciation of copper and nickel, and their bioavailability in mangrove ecosystem. Kinetic speciation study was performed to determine the concentrations ...
A new spectrofluorometric method for the determination of total arsenic in sediments and its application to kinetic speciation
(Taylor & Francis, 2012)
A simple and sensitive spectrofluorometric method has been developed for the determination of arsenic (As) using rhodamine-B as a fluorescent agent. This method is based on the reaction of As(III) with potassium iodate ...
Ultrafiltration technique in conjunction with competing ligand exchange method for Ni–humics speciation in aquatic environment
(Elsevier, 2013)
The combination of ultrafiltration technique with competing ligand exchange method provides a better understanding of interactions between Ni and different molecular weight fractions of humic acid (HA) at varying pH in ...
Effect of pH on transport and transformation of Cu-sediment complexes in mangrove systems
(Elsevier, 2018)
Impact of pH variation of overlying water column on transport and transformation of Cu-sediment complexes in the bottom mangrove sediments was investigated by using different metal extraction studies. The total Cu concentration ...
Oyster reef restoration in controlling coastal pollution around India: A viewpoint
(Elsevier, 2017)
Coastal waters receive large amounts of nutrients and pollutants from different point and nonpoint sources through bays and estuaries. Excess supply of nutrients in coastal waters may have detrimental effects, leading to ...
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 ...
Determination of dynamic metal complexes and their diffusion coefficients in the presence of different humic substances by combining two analytical techniques.
(Taylor & Francis, 2014)
The combined use of a competing ligand exchange (CLE) method and a diffusive gradient in thin films (DGT) technique in a quasi-labile system provides a better understanding of dynamic metal (Cu and Ni) complexes in the ...
