Abstract: This research was carried out to determine the nitrite contents of some fruits (apple, grape, melon, water-melon and carrot) collected from various bazaars in Konya city. The nitrate contents of fruit samples were determined with the Cadmium Acetate Colon Method. The results were given as mg/kg (fresh weight). Acording to the evaluation of the results, the apple samples contained 0.00-398.40, the grape samples contained 10.67-294-30, the melon samples contained 23.40-142.80, the water, melon samples contained 7.09-168.00 and the carrot samples contained 4.81-151.20 mg/kg nitrate. On the other hand, the apple samples contained 0.00-4.24, the grape samples contained 0.00-2.80, the water-melon samples contained 0.00-0.58 mg/kg nitrite. The melon and carrot samples had not contained the nitrite. Except one apple sample, the other fruit samples' nitrite contents were determined below of toxic levels.
