Abstract

Determination of nitrite, nitrate and N-nitrosamines in different types of milk and yogurt were carried out using colorimetric and GLC methods. This study shows that the average contents of nitrite and nitrate in milk were 0.045 μg/ml and 2.96 μg/ml respectively. Unidentified nitrosamines were observed in samples analyzed and neither DMN or DEN were detected. Selection of soft drink samples contained 3.9 μg/ml and 0.43 μg/ml of DMN and DEN respectively, water of industrial areas were observed to contained relatively high concentration of DMN (3.4 μg/ml) and DEN (0.25 μg/ml).
