Relationship between the lability of sediment-bound Cd and its bioaccumulation in edible oyster
Chakraborty, P.; Ramteke, D.; Chakraborty, S.; Chennuri, K.; Bardhan, P. (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 ... -

Seawater intrusion and resuspension of surface sediment control mercury (Hg) distribution and its bioavailability in water column of a monsoonal estuarine system
Chakraborty, P.; Jayachandran, S.; Lekshmy, J.; Padalkar, P.; Sitlhou, L.; Chennuri, K.; Shetye, S.S.; Sardar, A.A.; Khandeparker, R. (Elsevier, 2019)There is limited knowledge regarding seawater intrusion on Hg distribution in monsoon fed tropical estuarine systems during dry season (February to May). This study examined the influence of resuspension of estuarine ... -
Snapshot of environmental condition in different tropical estuarine systems by using S. cucullata (an edible oyster) as bio-indicator
Patra, P.; Mohandass, C.; Chakraborty, P. (2019)Accumulation of toxic metals and indigenous bacteria in oyster, (Saccostrea cucullata) and their impact on antioxidant enzyme activities in the biological system was studied and used to provide snapshot of environmental ... -
Speciation of Co, Ni and Cu in the coastal and estuarine sediments: Some fundamental characteristics
Chakraborty, P. (Elsevier, 2012)Kinetic and sequential extraction methods were used to investigate chemical speciation and distribution of Co, Ni, and Cu in the estuarine and coastal sediments collected from the central east coast of India. The kinetic ... -
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
Chakraborty, P.; Babu, P.V.R.; Acharyya, T.; Bandyopadhyay, D. (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 ... -
Study of cadmium-humic interactions and determination of stability constants of cadmium-humate complexes from their diffusion coefficients obtained by scanned stripping voltammetry and dynamic light scattering techniques
Chakraborty, P. (Elsevier, 2010)Diffusion coefficients of Cd–humate complexes are dependent on pH and [Cd]/[Humic] Acid (HA)] ratio in a Cd-HA system. These two factors mainly control the mass transport and complexation kinetics of Cd that may influence ... -
Ultrafiltration technique in conjunction with competing ligand exchange method for Ni–humics speciation in aquatic environment
Chakraborty, P.; Boissel, M.; Reuillon, A.; Babu, P.V.R.; Parthiban, G. (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 ... -
