摘要
Acute toxicity cffeets of diazinon on European cel (Anguilla anguilla ) was cxamined using short -term exposures in static conditions . The LC50 values were 0. 16. 0, 11, 0.09 and0.08 mg/l al 24. 48. 72 and 96 h exposure . respeclivcly. In additio the cels were exposedio 0.042 mg/ l of diazinon and bioaccumulation and clearance processcs of this insccticidein liver, muscle and gill tissties were studred . Bioconcentration factor (BCF ) of diazinonovcr 96 h cxposure Period was 1850 in livcr, 875 in gill and 775 in musele tissuc. Diazinoncliminalion from the sclccled lissucs was rapid. The excretion ratc constants of thisinsccticidc werc 0.108 h : for Iivcr, 0.055 h for gill and 0.016 h for muscle. Diazinonhalf-lives werc calculatcd as 16.6, 33.2 and 27 h tbr liver, musele and gill , respectively.Diazinon showed rclativcly short half lives in eel tissues.
