[Nitrite and nitrate content of foods sampled during national food quality monitoring].

Abstract

The aim of the french national inquiry of food quality is to ascertain the presence in food of many contaminants, in particular nitrates and nitrites. Because of variability of contamination in samples, a great number of determinations were carried out for each food kind (2296 determinations in 62 foods kinds). Nitrate amounts are in fact very high in beet roots, white beets, celery salads, radishes and green salads.
