متن کاملDetermination of Nitrate and Nitrite Residues in Smoked Caspian Kutum, Rutilus frisii kutum and Mullet, Liza auratus in the North of Iran
High dietary nitrate and nitrite intake may increase the risk of gastro-intestinal cancers due to the In vivo formation of carcinogenic chemicals known as N-nitroso compounds. In this study nitrate and nitrite residues in smoked Caspian kutum, Rutilus frisii kutum and mullet, liza auratus in the local markets (considered as batch no. 1, 2 and 3) of north of Iran were determined using Spectropho...
متن کاملHistopathological effects and toxicity of atrazine herbicide in Caspian Kutum, Rutilus frisii kutum, fry
This study aimed to investigate the toxic effects of atrazine herbicide on the fry of Caspian Kutum (Rutilus frisii kutum, Kamensky, 1901). First the 96-h LC50 of the fry were exposed to atrazine at the concentration of 24.95 ppm was determined. Then the toxicity of this herbicide on Caspian kutum fry exposed to the concentration of 12.47ppm (1/2 LC50), for four days was measured and compared w...
