Abiogenic origin of petroleum hydrocarbons: Need to rethink exploration strategies
(Current Science Association, 2008)The origin of petroleum hydrocarbons is a matter of debate since its discovery. During last several decades it is firmly believed that the origin of petroleum hydrocarbons is 'biogenic' due to chemical similarity between ... -
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 ... -
Acute toxicity and effect of some petroleum hydrocarbon on the metabolic index in Etroplus suratensis
(Society of Biosciences, Muzaffarnagar (India), 1997)Acute toxicity (LC sub(50)) and effect of some petroleum hydrocarbons (Toluene, Quinoline, Pyridine and Naphthalene) on the metabolic index (oxygen consumption rate) of an estuarine fish. Etroplus suratensis is reported. ... -
Candidates for the development of consortia capable of petroleum hydrocarbon degradation in marine environment
(Fostering International Coop. Res., UK, 1995)Bacteria and yeasts from different niches of the tropical Indian waters were screened for their hydrocarbon degrading potential using 1% w/v in artificial seawater over a period of 6 days. About 20% of the 75 bacterial and ... -
Crude oil degradation by phosphate-solubilizing bacteria
(Springer, 1996)Phosphate-solubilizing bacteria were isolated from tropical areas around the Indian peninsula. Two of the isolates showed high phosphatase activity. The isolates were identified as Klebsiella pneumoniae and Bacillus pumilus, ... -
Determination of petroleum hydrocarbons in sediment samples from Bombay harbour, Dharamtar creek and Amba river estuary
(Scientific Publishers, 1989)The surface sediment samples were collected by van Veen grab sampler during premonsoon, monsoon and postmonsoon seasons from Bombay harbour, Dharamtar creek and Amba river estuary Moisture content of the samples ranges ... -
Dissolved Petroleum Hydrocarbon Concentrations in some regions of the Northern Indian Ocean
(Elsevier, 1980)Dissolved petroleum hydrocarbons were measured in some parts of the Northern Indian Ocean using UV bsorbance technique with a clean up step. The concentration of oil ranged from 0.6 to 26.5 mu gl. Higher values were ... -
Dissolved petroleum hydrocarbons along the oil tanker route in the southern Bay of Bengal
(CSIR-NISCAIR, 1982)Concentrations of dissolved petroleum hydrocarbons during 3 cruises (Nos. 51, 66 and 68) of R V Gaveshani, along the oil tanker route, in the southern Bay of Bengal at 0, 10 and 20 m were 19.95 + or - 3.38, 16.78 + or - ... -
Dissolved Petroleum Hydrocarbons in the Andaman Sea
(CSIR-NISCAIR, 1981)Mean dissolved petroleum hydrocarbons, measured using UV-spectrophotometry, at 0 and 10m were 51 plus or minus 1 and 55 plus or minus 1.2 mu g/litre respectively; range of variation being between 28 and 83 mu g/litre. Very ... -
Distribution of Petroleum Hydrocarbons in Goa Coastal Waters
(CSIR-NISCAIR, 1980)Average hydrocarbon concentrations in water, plankton and sediment samples collected from the central west coast of India between 14 degrees 40'N and 15 degrees 50'N were 30.9 mu g/litre, 46.9 mu g/g dry wt and 7.1 degrees ... -
Effects of petroleum hydrocarbons on the growth of a microalga, Isochrysis sp. (Chrysophyta)
(NISCAIR, CSIR, 1997)Effects of water soluble fraction of Bombay High crude oil and heavy duty marine diesel on the growth of a microalga were examined and compared. Most concentrations of the oil depressed the growth rate in Isochrysis sp. ... -
Emulsifying activity of hydrocarbonoclastic marine yeasts
(Soc. Fish. Technol., Cochin, India, 1994)Marine yeast growth on four petroleum hydrocarbons induced the production of extracellular emulsifying agents (biosurfactants). Out of the 17 marine yeast isolates tested, 7 isolates, i.e., Candida parapsilosis, C. cantarelli, ... -
Estimation of carrying capacity of the Gulf of Kachchh, west coast of India in relation to petroleum hydrocarbon through oil spill modeling
(Maritime and Port Authority of Singapore, 2007)The Gulf of Kachchh (GoK) is a semi-enclosed basin located in the northern part of the west coast of India, and opens to the Arabian Sea. GoK is about 170 km long and 75 km wide at the mouth, and encompasses several ... -
How vulnerable is Indian coast to oil spills? Impact of MV Ocean Seraya oil spill
(Current Science Association, 2008)On 30 May 2006, a bulk carrier, MV Ocean Seraya ran aground along the Karwar coast spilling 650 tonnes of oil. Due to the rough SW monsoon, the spill spread to some beaches in south Goa. The aim of this communication is ... -
M. V. sea transporter oil spill and its environmental impact assessment
