This research deals with analytical methods for (16) polycyclic aromatic hydrocarbons (PAHs), nitrate and nitrite determination in Iraqi vegetables. Some PAHs are of proven carcinogenic activity; consequently, they exceed the limits of concentrations which approved by the European Food Safety Authority. Nitrate and nitrite also determined in Iraqi vegetables compared with the European specifications. There is no recommendations for the allowable limits of nitrate and Nitric in the fresh vegetables. The analytical determination for PAHs is carried out by high performance liquid chromatography, with ultraviolet (UV) detector, while the analytical determination for nitrate and nitrite is carried out by UV/Vis. Spectrometer.
