dc.description.abstractA harmonised TDS methodology was used to assess the Portuguese population’s nitrate baseline dietary exposure and the risk of exceeding the Acceptable Daily Intake (ADI). Nitrate occurrence in 164 TDS samples pooled based on 20 FoodEx2 groups, representative of 18 to 75 years old population diet, was determined using UV-HPLC. The ‘vegetables’ group had the highest mean nitrate concentration (353 mg/kg), followed by ‘starchy roots’ (62 mg/kg), ‘composite dishes’ (53 mg/kg) and ‘fruits’ (46 mg/kg). Lettuce contained the most nitrates (1729 mg/kg). The estimated mean nitrate exposure of 1.17 mg/kg bw/day, with 3.18% of individuals exceeding the ADI, was assessed on a semi-probabilistic approach using the MCRA software. Lettuce (28%) contributed most to nitrate exposure followed by vegetable soup (13%). Processed meat contribution to exposure was 0.86% and 2.44% (overall population and consumers only). At population level the nitrate estimated exposure (mean and 95th percentile) revealed no reason for concern.pt_PT
dc.description.abstractHighlights: Baseline mean nitrate exposure of Portuguese population was 1.17 mg/kg bw/day; Population’s 95 percentile nitrate exposure did not exceed the ADI; Main contributors to nitrate exposure were lettuce (28%) and vegetable soup (13%); Processed meat contributed to 0.86% of Portuguese population mean nitrate exposure; The study was performed using the TDS-Exposure project harmonised methodology.pt_PT
