It is aimed to
determine possible alterations in gill ultrastructure of Oreochromis niloticus individuals
exposed to certain concentrations of Lambda-cyhalothrin technical formulation
with Transmission Electron Microscope (TEM). At 7th, 14th and 21st days fish
exposed to 0.29 µg/L lambda-cyhalothrin were taken from the test solution. The
gills were fixed with 2.5% glutaraldehyde and post-fixed withosmium tetroxide, dehydrated
with ethanol and propylene oxide, and then embedded in resin. The ultra thin
sections were stained with uranyl acetate and lead, and examined with TEM. At 7th,
14th and 21st days the most common ultrastructural alteration was deformation
of pillar cells. The severity of cytopathological alterations were increased
with the duration of exposure.
