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 ...

(Indian Association for Limnology and Oceanography, 1984)
Quantitative distribution of meiobenthic faune of Varsova (Bombay, Maharashtra, India) waters was studied at four stations during November, 1979 to December, 1980. The nearshore areas represent a typical polluted environment ...
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 ...
The effect of mercury on the growth efficiency of Tilapia mossambica (Peters)
(Indian Association for Limnology and Oceanography, 1984)
Three concentrations of mercury (0.01, 0.04 and 0.4 ppm) were used for experiments on growth efficiency of Tilapia mossambica. Growth efficiencies were determined on a dry weight basis. High concentration of mercury (0.4 ...
