Arsenic toxicity is a global health problem affecting many
millions of people. Arsenic, the metal pollutant found naturally in groundwater
and unnaturally in mine waste sites and agricultural runoff, has been
considered toxic to humans for several millennia. In the present work the
effect of different concentrations of sodium arsenite on lipid metabolism in
Heteropneustes fossilis, and the chelating effect of synthetic zeolite was
studied from liver.
Fishes were exposed to two different concentrations of sodium
arsenite (200 ml and 400 ml of 1% solution), for 3 different durations (3days,
7 days and 15 days). The concentrations of total Cholesterol (F=6.35>3.84 at
5% P), HDL (F=14.91>6.83 at 5% P), LDL (F=10.11>1.39at 5% P) and
triglyceride (F=42.1>19.34 at 5% P) was found significantly increased along
with increasing concentration and duration of sodium arsenite. The toxic effect
was found recovered after the application of synthetic zeolite for all
parameters, i.e., total cholesterol (F=8.04>3.12 at 5%P), HDL
(F=14.96>6.83 at 5%P), LDL (F=1.57>1.39 at 5% P) and triglyceride
(F=26.28>19.34 at 5% P). Statistical analysis of the results was done by
two-way ANOVA.
The results suggest that zeolite is a potential compound for
decreasing significantly the load of toxicity of arsenic in aquatic fauna.
