The influence of dissolved petroleum hydrocarbon residues on natural phytoplankton biomass
(Elsevier, 1988)
The effect of dissolved petroleum hydrocarbons in the environment on phytoplankton biomass measured as chlorophyll a was studied near the oil tanker route in the southern Bay of Bengal. In the transect from 5 degrees N, ...
Effect of mining activities on the clam fisheries and bottom fauna of Goa estuaries
(Indian Academy of Sciences, Bangalore, 1986)
Comparison of two clam beds and associated benthic fauna, in Mandovi and Cumbarjua canal estuarine system of Goa, India, severely affected by massive inputs of mining rejects, revealed that, in less than 10 years (1972-73 ...
Relative toxicity of oil dispersants to Mytilus viridis and Macrobrachium idella
(CSIR-NISCAIR, 1984)
There was a great variation in the relative toxicity of different oil dispersants. Dispersant IB 2/80 was most toxic and dispersant IB 11/80 was not lethal at the highest concentration tested. The ranking order of the ...
Chlorinated pesticide residues in marine sediments
(Elsevier, 1988)
A number of organochlorine pesticides residues, aldrine, gamma BHC, dieldrine, and DDT were detected and quantified from the marine sediments collected along the east coast of India by gas chromatography using an electron ...
Effect of industrial effluents on biota: a case study off Mangalore, west coast of India
(CSIR-NISCAIR, 1987)
The inshore waters off Mangalore, receiving industrial effluent discharge were studied for phytoplankton, zooplankton and benthic populations, from December 1984 to May 1985. Total phytoplankton population varied from 7 ...
Effects of dispersants on microbial growth and biodegradation of crude oils
(Indian Association for Limnology and Oceanography, 1984)
Four oil spill dispersants when used along (0.1% V/V) or in combination with Saudi Arabian Crude (0.5% V/V) were non-toxic to Arthrobacter simplex and Candida tropicalis. At a higher concentration of 0.6% (V/V) only D2 was ...
Petroleum hydrocarbon contamination along oil tanker routes in the Arabian Sea
(CSIR-NISCAIR, 1984)
Concentration of petroleum hydrocarbons in seawater from the oil tanker route region between 0-25 N and 45-75 E were estimated using UV-absorbance and fluoroscence techniques. Concentrations in surface waters averaged 9.2 ...
Use of electrophoresis and immunoelectrophoresis in taxonomic and pollution studies
(Indian Academy of Sciences, Bangalore, 1984)
Studies were conducted on the electrophoresis of blood serum and eye lens proteins of 5 fishes and immunoelectrophoresis of the soluble lens proteins of 10 fishes. The effects of a toxic pollutant (mercury) on the ...
Organic carbon content of zooplankton from the nearshore waters of Bombay
(CSIR-NISCAIR, 1983)
Organic carbon content of zooplankton in the Versova Creek and Thana Creek (polluted areas), off Versova and off Mahim, Bombay, India (relatively unpolluted areas) varied respectively from 21.4-30, 13.2-38.4, 21.6-30 and ...
Pollution Effects Monitoring with Foraminifera as Indices in the Thana Creek, Bombay Area
(Taylor & Francis, 1982)
In the study area, the pollution effect on the foraminiferids is intense, hence highly reliable and measurable. The relative sensitivity of tolerance of the biota is sharply variable and dependent upon the nature of the ...
