Dimethoate pesticide and bacilar bio-fertilizer are two common inputs widely used in Iranian agriculture which washed by run-off and transmitted to aquatic ecosystems where they can cause biological and physiological problems for aquatic organisms. The objective of this research was to study the combined effects of dimethoate pesticide and bacilar bio-fertilizer on blood biochemical parameters of common carp. To this end, 270 fish were selected and allocated into 9 treatment including: control group, treatment A (0.016 mg/L pesticide), treatment B (0.032 mg/L pesticide), treatment C (0.1 ml/L fertilizer), treatment D (0.2 ml/L fertilizer) and combined treatments AC, AD, BC, BD, in triplicate. Fish were exposed to different concentration of dimethoate pesticide and bacilar fertilizer for 14 days. The blood biochemical parameters including Triglyceride (TG), Cholesterol, Glucose, Protein, Albumin, and Globulin were measured. The amount of TG in treatments A, C and D showed significant increment in comparison with control group. The amount of Cholesterol in treatments A and B had been increased in comparison with control group but in treatment AD had been decreased. The amount of Glucose showed no significant differences in all treated groups in comparison with control group. Protein had been increased in treatments C, D and other combined treatments except AC. The amount of Albumin in all treatments except A had significantly increased. The amount of Globulin in all treatments except B did not have any significant differences with control group. The results of this study revealed that combined treatment of dimethoate and bacilar bio-fertilizer did not showed remarkable differences from their singular treatments and more research with higher concentrations of pollutants are required for better understanding of their interactional effects.

The objectives of the present investigation were to study the bioaccumulation of Aldrin, Diazinon and Endrin pesticides in the edible muscle tissues of Tinca tinca, Rutilus frisii kutum, Carassius auratus, Cyprinus carpio, Silurus glanis and Esox lucius that were caught at various stations in the west, east and center of the Anzali Wetland and to compare the results with the standards of the World Health Organization (WHO). The concentration of organochlorine pesticide was determined using Gas Chromatography (GC) equipped with an electron capture detector. The concentration of organophosphorus pesticide was determined using Gas Chromatography/Mass Spectrometry (GC/MS). The highest concentration of Diazinon was detected in Esox lucius from the wetland east station (20.25 ppb). Significant differences were not observed in the amounts of Diazinon and Aldrin pesticides in the muscles of fish samples in various stations (P>0/05). The highest amounts of Endrin were observed in the muscle of Cyprinus carpio from the wetland east and west stations which were significantly different compared to that of other fish species (P
