Abstract:
The present work is a base line attempt to investigate and assess the
toxicities of three surfactants viz. anionic sodium dodecyl sulfate (SDS), non
ionic Triton X-1OO (TX-IOO) and cationic cetyl trimethyl ammonium bromide
(CTAB). These compounds represent simple members of the often neglected
group of aquatic pollutants i.e. the anionic alkyl sulfates, non ionics and the
cationics. These compounds are widely used In plastic industry,
pesticide/herbicide formulations, detergents, oil spill dispersants, molluscicides
etc. The test organisms selected for the present study are the cyanobacterium
Synechocystis salina Wislouch representing a primary producer in the marine
environment and a fresh water adapted euryhaline teleost Oreochromis
mossambicus (peters) at the consumer level of the ecological pyramid. The fish
species, though not indigenous to our country, is now found ubiquitously in fresh
water systems and estuaries. Also it is highly resistant to pollutants and has been
suggested as an indicator of pollution in tropical region .
