Nitrate (NO<sub>3</sub><sup>–</sup>) and nitrite (NO<sub>2</sub><sup>–</sup>) levels of a total 1195 samples of nine different vegetables (lettuce, potato, cabbage, carrot, string beans, tomato, cucumber, cauliflower and pepper) collected at several locations of an intensive agricultural area in Slovenia were analysed during a period of 13 years. The content of NO<sub>2</sub><sup>–</sup> and NO<sub>3</sub><sup>–</sup> ions in commercial mature samples was determined using a segmented flow analyser. The average NO<sub>3</sub><sup>–</sup> content was the highest in lettuce (962 mg/kg), cabbage (795 mg/kg), string beans (298 mg/kg), carrot (264 mg/kg), cauliflower (231 mg/kg), potato (169 mg/kg) and was moderately high in cucumber (93 mg/kg) and pepper (69 mg/kg). A low NO<sub>3</sub><sup>–</sup> content was found in tomato (2<sup>–</sup> did not exceed 0.5 mg/kg, with the exception of potato (1.08 mg/kg). Six samples of lettuce exceeded the maximum permissible level of NO<sub>3</sub><sup>–</sup> according to current European Union (EU) legislation. Based on the results of our investigation, we assessed the approximate daily intake (DI) of NO<sub>3</sub>– and NO<sub>2</sub><sup>–</sup> to human body. The results indicated that with the consumption of potato, the daily intake per inhabitant is close to the acceptable DI permitted in EU.

Abstract. In a study with 12 calves on milk nutrition, the course of methemoglobinemia as well as ttansrenal passage of nitrates and nitrites after single per os administrations of 4 g NaNO2 per animal and 30 g KNO3 per animal in the form of water Solutions has been observed. The response of the organism of calves to per os administered doses of sodium nitrite and potassium nitrate was observed by the determination of tlie methemoglobin percentage in blood and the nitrate and nitrite content in urine before the administration ofthe respective dose and after h 1, 2, 3 and 4 after the administration. A significant elevation in the values of methemoglobin was recorded after h 2 after the administration of 4g NaNO3 per animal. The mean value of methemoglobin in blood was 18.84% of total hemoglobin. A slight decline in the values occurred as early as after h 3 after the administration. Of clinical signs, cyanosis of visible mucosae was observed. The highest nitrite and nitrate values in urine were determined after h 2 after per os administration of 4g NaNO2, With the administration of 30g KNO3 per animal, the most pronounced elevation in methemoglobinemia was observed after h 3, when the means values of methemoglobin was 11,75%. Of clinical signs, only slight cyanosis of mucosae was detectable. Maximum values of nitrates in urine of experimental calves after h 3 after the administration of 30 g KNO3 per animal, with the mean value of 29,9 mM NO3−1 clearly demonstrate a good transrenal passage of nitrates in calves on milk nutrition.
