Examine the nitrate concentration of a few distinct plants from various places in North Sinai Governorate (Arish City). This study is concerned with three main topics: (i) the contribution of various well-known leafy plants to dietary nitrate consumption by people; (ii) the dietary, environmental, and physiological factors regulating nitrate accumulation in plants; and (iii) the adverse and beneficial effects of nitrate on human health. The Locations (Airport Road Location (A), Wadi EL-Arish1(W), and Wadi EL-Arish 2(WI)) include this district. Rosemary, Breckl and thyme, Mentha, Black Mulberry, Jute mallow, Alfalfa, Basil, Maize green chop, Kurrat, Pursley, Arugula, and Horse mint were among the 12 varieties of plants represented by the total of 19 plants that were randomly selected from farms in three distinct regions (Arish City). The results revealed that the plant has a significant impact on the nitrate concentration, with Arugula having the greatest nitrate content while Kurrat and Horse mint having the lowest. The plants has an impact on the nitrate content. The nitrate concentrations of the plants studied exhibit a considerable locational effect. The outcomes of the investigation showed that the amounts of nitrate content were appropriate. To elaborate these findings with more samples and diverse plants, however, more work is required.
