Acetylcholinesterase activities in marine snail (Cronia contracta) as a biomarker of neurotoxic contaminants along the Goa coast, West coast of India
(Springer, 2006)The measurement of acetylcholinesterase (AChE) activity is used worldwide as a biomarker of environmental contamination due to neurotoxic substances. In the present study the AChE activities was measured in marine snails ... -
Barium as a productivity proxy in continental margin sediments: A study from the eastern Arabian Sea
(Elsevier, 2002)Barium, aluminium, cadmium and uranium were analyzed in 112 surface sediment samples from the western continental margin, of India. Excess Ba (Ba sub(xs)) concentrations are high at the SW margin of India, an area of high ... -
Bio-accumulation of some trace metals in the short-neck clam Paphia malabarica from Mandovi estuary, Goa
(Elsevier, 2006)Monthly collections of the clam Paphia malabarica were made for period of 1 year from May 2002 to April 2003 from Verem, Mandovi estuary, Goa, India. Clams were categorised into two groups, 25-35 mm (small size) and 35-40 ... -
Concentration of metals in fishes from Thane and Bassein creeks of Bombay, India
(Council of Scientific and Industrial Research, New Delhi, 1999)Concentration of Cu, Zn, Cd, Pb and Ni in different tissues of 10 species of fishes from Thane and Bassein creeks were estimated for a period of 15 months. The trend in bioaccumulation indicated that irrespective of species ... -
Concentration of metals in shrimps and crabs from Thane-Bassein creek system, Maharashtra
(Council of Scientific and Industrial Research, New Delhi, 1999)Levels of Cu, Zn, Cd, Pb and Ni in shrimps and crabs from Thane-Bassein creek system, Maharashtra, India were evaluated for a period of one year and reported as baseline for future monitoring of this vital ecosystem. The ... -
Detection of pollutants in marine organisms and in the environment as markers of environmental quality
(Pennsilvania Academy of Science, 2005)This chapter presents an overview of various techniques of detection of different types of pollutants such as organochlorine pesticides (e.g. DDT, HCHs, aldrin, dieldrin, endrin, Hepox, heptaclor), polychlorinated biphenyls ... -
Determination of Cd, Pb and Cu in Mandovi estuary by differential pulse anodic stripping voltammetry
(CSIR-NISCAIR, 1984)Dissolved labile and non-labile (organically associated) concentration of Cd, Pb and Cu in Mandovi Estuary, Goa, India have been measured for 1 y (February 1980 to January 1981). Percentage non-labile form varies from 0-50% ... -
Distribution of various forms of Cd, Pb and Cu in the Wadge Bank region (Arabian Sea)
(CSIR-NISCAIR, 1986)Labile, nonlabile and particulate forms of Cd,Pb and Cu were determined in 29 water samples collected from a depth of 5 m, from the Wadge Bank area. Labile Cd varied from 0.1 to 0.2 mu g.l-1 while nonlabile fraction was ... -
Inorganic combined nitrogen budget of the Arabian Sea: Some geochemical and climatic implications
(Waseda University, Tokyo, 1992)Estimates of the local sources and sinks of inorganic combined nitrogen in the Arabian Sea suggest a net loss of sup(-)3 x 10 sup(13) gN y sup(-1). This seems to be made up largely by the upward flux facilitatEd. by a high ... -
Mercury, Cadmium and lead in different Tissues of Fishes and in Zooplankton from the Andaman Sea
(CSIR-NISCAIR, 1983)Several fishes, representing different trophic levels, and some zooplankton samples were analysed for Hg, Cd and Pb There is a wide variation in the concentrations of these elements Hg is quite low in practically all the ... -
Petroleum hydrocarbons and trace metals in Visakhapatnam harbour and Kakinada Bay, east coast of India
(NISCAIR, CSIR, 1996)High concentrations of PHC were observed in the inner channels (viz. South lighter canal, Northern arm, North Western arm and Western arm) of Visakhapatnam Harbour, Andhra Pradesh, India. The estimation of trace metals ... -
Speciation and behaviour of Cd, Pb and Cu in Zuari Estuary, west coast of India
(NISCAIR, New Delhi, 1993)Dissolved labile and nonlabile forms of Cd, Pb and Cu in Zuari Estuary, Goa, India measured for a period of 14 months showed lowest concentrations during the SW monsoon (June-September) while maximum concentrations were ... -
Toxicity of some heavy metals to Copepods Acartia Spinicauda and Tortanus Forcipatus
(CSIR-NISCAIR, 1981)Copper was most toxic to the species tested followed by cadmium and zinc The estuarine species Acartia spinicauda was more sensitive to the toxicants that the marine species Tortanus forcipatus The 48 hr LC50 values are presented. -
Use of Fourier Transform Infrared (FTIR) spectroscopy to study cadmium-induced changes in Padina tetrastromatica (Hauck)
(Libertas Academica, 2008)The aim of this study is to adopt the approach of metabolic fingerprinting through the use of Fourier Transform Infrared (FTIR) technique to understand changes in the chemical structure in Padina tetrastromatica (Hauck). ...
