Resumo(s)
This study reports the levels of nitrate and nitrite of 34 vegetable samples, including different varieties of
cabbage, lettuce, spinaches, parsley and turnips, collected in several locations of an intensive agricultural
area (Modivas, Vila do Conde, northern Portugal). Nitrate levels ranged between 54 and
2440 mg NO-3 kg-1, while nitrite levels ranged between 1.1 and 57 mg NO-2 kg-1. The maximum residue
levels established for nitrate in spinach and lettuce samples were not exceeded. Nitrate and nitrite levels
reported in the literature for the same type of samples are reviewed, as well as the contribution of
vegetables to nitrate and nitrite dietary exposure of populations.
