Popis:	Nitrate concentrations in 326 recent vegetables and berries sold in Niigata, located in central Japan, were investigated. Maximum nitrate concentrations of 6600 mg kg−1 were detected in samples of komatsuna (Brassica campestris var. perviridis) and mizuna (B. campestris L.). Mean concentrations ranged from 4 mg kg−1(blueberry) to 3500 mg kg−1 (mizuna). Concentrations in spinach ranged from 10 to 6000 mg kg−1 (mean 1500 mg kg−1). Nitrate intake from spinach and Japanese radish (Raphanus sativus) were estimated to be 0.7 and 0.8 mg kg−1 day−1, respectively. These values are equivalent to 19% and 23% of the acceptable daily intake (ADI). Nitrate intake at the 90th percentile was estimated to be 1.3 mg kg−1 day−1 (35% of the ADI) from spinach and 1.6 mg kg−1 day−1 (43% of the ADI) from Japanese radish.
