Abstract


In this study effects of Pb and Pb+NTA mixtures on the activity of alkaline phosphatase (ALP) in the blood tissues of Oreochromis niloticus were investigated. The fish were exposed Pb (0.1 mg/L Pb ve 1.0 mg/L Pb) and Pb+NTA ((0.1 mg/L Pb+0.3 mg/L mixtures NTA ve 1.0 mg/L Pb+3.0 mg/L NTA) for 7 and 21 days. ALP activity in the blood tissue was determined by spectrophotometric methods. In both exposure concentrations ALP activity increase with increasing exposure periods. activity in the blood tissues of fish exposed to Pb for 7 and 21 days was lower when compared to those exposed to Pb+NTA: As a result, it is thought that the toxic effect of lead on O. niloticus on biochemical parameters is prevented by NTA.
