Vegetables were classified into three groups included leafy (lettuce and cabbage), tuberous (potato and onion), and bush (tomato and cucumber) products. Three samples of each 20 vegetable types were obtained from agricultural lands and the nitrate levels were measured using a High-Performance Liquid Chromatography (HPLC) system (KNAUER) equipped with a UV detector (UV-Detector-K2500). The mean nitrate concentration levels in leafy, bush and tuberous vegetables were 685.87±52.87, 153.48±20.15 and 63.58±27.32 mg/kg, respectively. The mean of hazard quotient (HQ) in adults and children in region 1 were 0.028 and 0.096; for region 2 were as 0.027 and 0.096; and for region 3 were 0.028 and 0.090, respectively (Figure 1-3). The HQ values due to nitrate for adults and children in three regions were ˂1, hence consumers are in acceptable health risk. While nitrates in vegetables were within acceptable health risk range, ongoing monitoring and management of nitrate levels are necessary to mitigate potential health hazards. https://jpoll.ut.ac.ir/article_104653_cda1c76e564dff0342cb74f86bda7ddf.pdf
