toxicity and protective effect of zeolite by using serum enzymes activities of <i>Oreochromis niloticus </i>. For this purpose
fish were exposed to 0.01 and 0.05 mg/L Hg and 0.01 mg/L Hg+0.01 g/L Zeolite
and 0.05 mg/L Hg+0.05 g/L Zeolite for 4 and 21 days and alanine
aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase
(ALP), and lactate dehydrogenase (LDH) activities were measured in blood serum. </span> <span style="font-size:8pt;">In the
exposures of mercury alone and mercury+zeolite mixtures, significant changes
were determined in all enzymes activities due to medium concentration and
exposure period. ALT, AST, and ALP activities significantly increased at 4 and
21 days in both exposure concentrations of mercury and at 21 days in higher
concentration of mercury+zeolite mixture </span> <span lang="en-gb" style="font-size:8pt;" xml:lang="en-gb"> (P˂0.05). LDH activity elevated all tested concentrations of mercury and
mercury+zeolite mixtures after the both exposure periods (P˂0.05). In the
present research it was determined increases </span> <span style="font-size:8pt;"> in activities of serum enzymes of <i>O. niloticus </i> were higher in the mercury
