Bioaccumulation of metals in the East Calcutta wetland ecosystem
The concentrations of heavy metals in wastewater were reduced by 25 to 45% and total Cr was reduced by 95%, on the course of the 40 km long journey of the composite wastewater from the sources to river mouth via the wastewater carrying canal and the stabilization pond. Expand
A study on the phytoaccumulation of waste elements in wetland plants of a Ramsar site in India
The present study indicates the importance of identification and efficiency of metal uptake and accumulation capabilities by plants in relation to their applications in remediation of a contaminated East Calcutta Wetland ecosystem. Expand
Envelope protein gene based molecular characterization of Japanese encephalitis virus clinical isolates from West Bengal, India: a comparative approach with respect to SA14-14-2 live attenuated
Evolution of JEV at a local level is reported and it is demonstrated that isolate-specific crucial amino acid substitutions were closely related to neurovirulence/neuroinvasiveness of JE. Expand
Influence of socio-economic status and environmental factors on serologically diagnosed Japanese encephalitis cases in the state of West Bengal, India during 2005-2010
It is concluded that socio-economic status and environmental conditions were statistically significant contextual risk factors for serologically diagnosed JE incidences in West Bengal where JE is proved to be endemic in nature and such study constitutes a new report of this kind in the region.

Habitat Preference and Diversity of Anuran in Durgapur, an Industrial City of West Bengal, India
Anuran diversity study was conducted for one year between June 2008 and August 2009 at Durgapur, an industrial city of West Bengal, India. Nine species under four families of the Order Anura wereExpand
Butterfly diversity and abundance with reference to habitat heterogeneity in and around Neora Valley National Park, West Bengal, India
Findings made during this study indicate negative influence of anthropogenic intervention on overall butterfly diversity from the present location and butterflies that showed high occurrences were Indian Tortoise Shell, Yellow Coster and Himalayan Five Ring. Expand
Comparison of avifaunal diversity in and around Neora Valley National Park, West Bengal, India
Anthropogenic intervention has led to conversion of much of the global diversity by means of habitat alterations. The present study was carried out to investigate the importance of habitat qualityExpand
Ecotoxicological Assessment of Tannery Effluent Using Guppy Fish (Poecilia reticulata) as an Experimental Model: A Biomarker Study
Investigation of acute and chronic toxicity of tannery effluent on a fish biosystem by examining oxidative stress enzyme expression in different organs including liver, gills, and muscle suggests elevated activities of stress enzymes in fish upon exposure to environmental pollutants may serve as important biomarkers for oxidative stress.

Potential of Wetland Macrophytes to Sequester Carbon and Assessment of Seasonal Carbon Input into the East Kolkata Wetland Ecosystem
Wetland is the largest sink of C among entire terrestrial C pool, however, species specific efficiency of wetland macrophytes for sequestering C is not studied well. This study reports seasonalExpand
Assessment of the spatio-temporal distribution of soil properties in East Kolkata wetland ecosystem (A Ramsar site: 1208)
The present investigation was made to characterize spatial and temporal variations in soil properties and to evaluate possible differences that could be dependent on the tannery effluent discharges,Expand
