Linear alkyl benzene sulfonate is a group of
anionic detergents widely used in domestic and industrial applications. It
causes adverse effects by mixing with aquatic environments. Chemicals mixing
with aquatic environments affect fauna and flora at different levels. This
study was carried out to determine the toxicity of linear alkyl benzene
sulfonate for the larvae of tarek (Alburnus
tarichi Güldenstädt, 1814), a fish living in the Van Lake basin which has
economic and ecological value. The chemical was administered at concentrations
of 0.0, 0.6, 1.2, 1.8, 2.4, and 3.0 mg L-1 in the acute test and
0.0, 1.2, and 2.4 mg L-1 in the chronic test. Tests were carried out
using 100 larvae in each group. Bioassays were carried out at mean temperature
of 20.9 ± 0.4 °C. A median lethal concentration of 4.883 (4.099‒6.482) mg L-1
at 96 hours was calculated for the larvae. Glutathione content, superoxide
dismutase and glutathione S-transferase activity decreased significantly at 1.2
mg L-1 and increased significantly at 2.4 mg L-1 compared
to controls (P<0.05). The
malondialdehyde content increased significantly depending on the increase in
chemical concentration (P<0.05). Linear alkyl benzene sulfonate is toxic
to tarek larvae in terms of the measured biochemical parameters.
