  The discharge of textile effluents into the environment without appropriate treatment poses a serious threat for the aquatic organisms. The present study was undertaken to investigate biochemical response of crayfish Astacus leptodactylus exposed to textile wastewater (TW) treated by indigenous white rot fungus Coriolus versicolor. Glutathione S-transferase (GST), cytochrome P450 1A1 (CYP1A1), and acetylcholinesterase (AchE) levels in hepatopancreas and abdomen tissues of crayfish exposed to untreated, treated, and diluted rates (1/10) in both TW during 24 and 96 h were tested. Physiochemical parameters (electrical conductivity (EC), chemical oxygen demand (COD), pH, and total dissolved solid (TDS)) of TW were determined before and after treatment. Physiochemical parameters of TW decreased after treatment. The GST activity and AchE were generally increased, but CYP1A1 activity was decreased in hepatopancreas tissue of crayfish exposed to different kinds of untreated TW. After treatment by indigenous white rot fungus (C. versicolor), GST and CYP1A1 activities were returned to control values, while AchE activities were increasing further. In this study, only GST and CYP1A1 activities of A. leptodactylus confirmed the efficiency of TW treatment with C. versicolor.

  Use of acetylcholinesterase, glutathione S-transferase and cytochrome P450 1A1 in Capoeta umbla as biomarkers for monitoring of pollution in Uzuncayir Dam Lake (Tunceli, Turkey)

  Uzuncayir Dam Lake is one of the most important water bodies in Tunceli. It is polluted by domestic wastewaters together with natural contamination and pesticides, which have had cumulatively negative effects. This study analyzes the effects of pollution by using the fish species, Capoeta umbla as a sentinel species, with a biomarker approach. The approach comprehends a general biomarker of individual fish health, the condition factor and specific biomarkers of contaminant exposure such as glutathione S-transferase (GST) and cytochrome P450 1A1 (CYP1A1) and acetylcholinesterase (AChE) activity. The general water physico-chemical parameters were measured at each sampling sites during each fish-sampling period. Strong seasonal and locational variations were observed among selected markers. In conclusion, the multibiomarker approach used in the present study clearly revealed differences in the fish health among reference and potentially contaminated sites. The study shows that changes of biomarkers such as acetylcholinesterase, glutathione S-transferase and cytochrome P450 1A1 might be useful for the assessment of environmental contamination in the Uzuncayir Dam Lake (Tunceli, Turkey).
