Bioaccumulation of heavy metals in commercially important marine fishes from Mumbai Harbor, India.
(Elsevier, 2014)Seventeen commercially important marine fish species were caught in Mumbai Harbor using a trawl net and evaluated using Atomic Absorption Spectroscopy and ICP-OES. It was found that certain species of fish contained lower ... -
Bioaccumulation of toxic metals by fish in a semi enclosed tropical ecosystem
(Taylor and Francis, 2006)Concentrations of Zn, Cd, Pb, and Mn in different tissues of 17 species of fish from a tropical estuary (Cochin backwaters) are presented. The metal electivity index (MSI) was found to be a better tool compared with the ... -
Chemical and environmental studies in ice and waters in and along Antarctica
(Current Science Association, 1983)During the First Indian Ocean Expedition to Antarctica in anstral summer of 1981-82, some chemical investigations were carried out on the ice and waters of the Antarctic continent and along NE-SW transect in the southwestern ... -
Distribution of Al, Mn, Ni, Co & Cu in the Non-Lithogenous fractions of Sediments of the Northern Half of the Western Continental Shelf of India
(CSIR-NISCAIR, 1980)Higher amounts of elements are associated with the nonlithogenous fractions of the fine grained terrigenous sediments of the innershelf region with low carbonate content than with the corresponding fractions of the coarse ... -
Distribution of Fe, Mn, Ni, Co, Cu and Zn in Non-Lithogenous Fractions of Sediments of Gulf of Kutch
(CSIR-NISCAIR, 1980)Contributions made by non-lithogenous fractions of sediments constitute a significant portion of the concentrations of the elements associated with the total sediment samples. The minor differences found in their distribution ... -
Environmental magnetism and application in the continental shelf sediments of India
(Elsevier, 2009)Mineral magnetic and geochemical analyses were carried out on surface sediments from the continental shelf of India. The purpose of this study is to examine the environmental assessment of heavy metal concentrations and ... -
Foraminifers as indicators of marine pollution: A culture experiment with Rosalina leei
(Elsevier, 2004)In order to develop a viable foraminiferal proxy for heavy metal pollutants, juvenile specimens of Rosalina leei were subjected to different mercury concentrations (0 -180 ng/l). Initially considerable growth was observed ... -
Geochemistry of calcareous sediments from the SW Carlsberg Ridge: Evidence for deeper carbonate compensation depth
(NISCAIR, CSIR, 1995)Concentration of Mn, Fe, Ni, Co, Zn, Ca, Mg, K, Al, Si, Ti, P and CaCO sub(3) show wide range for the calcareous sediments from SW Carlsberg Ridge (CR). Compared with the average pelagic clays, the CR sediments are enriched ... -
Geochemistry of calcareous sediments from the SW Carlsberg Ridge: Evidence for deeper carbonate compensation depth
(NISCAIR, CSIR, 1995)Concentration of Mn, Fe, Ni, Co, Zn, Ca, Mg, K, Al, Si, Ti, P and CaCO sub(3) show wide range for the calcareous sediments from SW Carlsberg Ridge (CR). Compared with the average pelagic clays, the CR sediments are enriched ... -
Heavy metal accumulation in a flow restricted, tropical estuary
(Elsevier, 2005)Levels of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn), organic carbon content and textural characteristics in the surficial sediments of Cochin estuary (SW coast of India) and adjacent coast are presented. ... -
Heavy metal burden in coastal marine sediments of north west coast of India in relation to pollution
(National Institute of Oceanography, Goa, India, 2009)Human activities in the marine zone of India are mainly confined to the inner shelf where water depths are <50 m. Considering the vastness of the coastal area, the data on contaminants including metals in seawater, marine ... -
Heavy metal pollution exerts reduction/adaptation in the diversity and enzyme expression profile of heterotrophic bacteria in Cochin estuary, India
(Elsevier, 2011)Over the past three decades heavy metal pollution has increased substantially in Cochin estuary, south west coast of India. The distribution, diversity and enzyme expression profile of culturable microbial population along ... -
Heavy metal tolerance in the psychrotolerant Cryptococcus sp. isolated from deep-sea sediments of the Central Indian Basin
(John Wiley & Sons, 2013)A deep-sea isolate of the psychrotolerant yeast Cryptococcus sp. (NIOCC#PY13) obtained from polymetallic nodule-bearing sediments of the Central Indian Basin was examined for its capacity to grow in the presence of various ... -
Heavy metals and zooplankton with special reference to Minamata (Japan) mercury pollution - A case study
(Society of Biosciences, Muzaffarnagar, India, 1993)Zooplankton samples were collected from nine stations in the three inland sea regions (Minamata Bay, Yatsushiro-Kai, and Ariake-Kal) along the western coast of Japan Between September 1980 to December 1986 and were analysed ... -
Heavy metals in fishes from coastal waters of Cochin, southwest coast of India
(NISCAIR, CSIR, 1997)The concentration levels of copper, zinc, manganese and iron have been determined in marine fishes from Cochin area which is one of the major fishing zones along the west coast of India. The concentration of heavy metals ... -
Heavy metals in Mindhola river estuary, India
(Elsevier, 1988)The heavy metal concentrations are studied along the Mindhola river estuary. Surface and bottom water samples were collected using Niskin Sampler. The sediment samples were collected using a Van Veen grab. The heavy metal ... -
Mercury-Resistant Marine Bacteria and their Role in Bioremediation of Certain Toxicants
(2004)The primary objective of this study was to isolate and enumerate mercury-resistant bacteria and to compare their occurrence and distribution spatially and temporally along the Indian coasts. As coastal waters experience ... -
Pollution of the seas around India
(Indian Academy of Sciences, Bangalore, 1988)The state of marine pollution along the 7000 km long coastline and 2.015 x 106km exclusive economic zone of India is summarized. The coastal water receives 4.1 km3 of domestic sewage and 0.41 km3 of industrial wastes. ... -
Potential of mercury-resistant marine bacteria for detoxification of chemicals of environmental concern
