چکیده انگلیسی
The effect of bleached kraft pulp mill effluent (BKPME) persistent compounds on phagocyte activities and its organ-specific influence in gill, kidney and liver was studied in European eel (Anguilla anguilla L.). Eels were caged and plunged at 3 different sites-50Â m (site 1), 100Â m (site 2) and 2000Â m (site 3) away from the end of the closed BKPME discharging channel for 8 and 48Â h. Gill, head kidney and peritoneum phagocytes oxidative burst activity (OBA) was measured by the nitroblue tetrazolium reduction assay whereas lipid peroxidation (LPO) in eel gill, kidney and liver was measured by thiobarbituric acid reaction. A significant gill OBA induction was found at 8Â h on site 2, and on sites 1, 2 and 3 at 48Â h exposure. However, in head kidney and peritoneal exudate phagocytes, OBA induction was significant only at sites 2 and 3 after 48Â h exposure. In those particular sites, a significant increase in gill, kidney and liver LPO was measured that is assumed to result from OBA induction. Considering OBA and LPO, gill is the most affected tissue compared to kidney and liver. Gill vulnerability towards peroxidative damage was demonstrated at 8Â h on site 2 and at 48Â h on sites 1, 2 and 3, whereas in kidney was observed at sites 2 and 3 only at 48Â h. Liver LPO increased at site 2 only after 48Â h exposure. Our results demonstrate that the OBA activation pattern in gill and kidney is associated with the induced peroxidative damage extent in those organ, together with water pollution the exposure route, resulting from previous BKPME effluent sediment contamination which may affect the activation pattern of circulating fish phagocytes.
