In recent years, contamination of water resources, with pollutants such as nitrate and nitrite, has significantly increased. These compounds can have harmful effects on human health, especially children such as methemoglobinemia. The main objective of this study was to measure the concentration of nitrate and nitrite and its health-risk assessment in the rivers entering Taham dam in Zanjan. USEPA Method was used to assess the health-risk of nitrate and nitrite. According to the obtained results, the concentration of nitrate and nitrite was in the range of 0.51-14.93 mg/l and 0.001-0.061 mg/l, respectively. According to the results, the mean of the CDI for nitrate and nitrite was 9.5210 and 3.6310 mg/kg/day, respectively. Furthermore, the mean HI for nitrate and nitrite was 5.9710 and 3.6310, respectively. The concentration of nitrate and nitrite in rivers was lower than the WHO and Iran guidelines. Based on the results, the HI value in all samples was less than 1 which indicating the non-carcinogenic effects of nitrate and nitrite in these rivers.
近年来，水资源受到硝酸盐和亚硝酸盐等污染物的污染显著增加。这些化合物会对人体健康产生有害影响，尤其是对儿童，如导致高铁血红蛋白血症。本研究的主要目的是测量赞詹进入塔哈姆大坝的河流中硝酸盐和亚硝酸盐的浓度及其健康风险评估。采用美国环境保护局（USEPA）方法评估硝酸盐和亚硝酸盐的健康风险。根据所得结果，硝酸盐和亚硝酸盐的浓度分别在0.51 - 14.93毫克/升和0.001 - 0.061毫克/升范围内。根据结果，硝酸盐和亚硝酸盐的日均摄入量（CDI）均值分别为9.52×10和3.63×10毫克/千克/天。此外，硝酸盐和亚硝酸盐的危害指数（HI）均值分别为5.97×10和3.63×10。河流中硝酸盐和亚硝酸盐的浓度低于世界卫生组织（WHO）和伊朗的指导标准。基于这些结果，所有样本的HI值均小于1，这表明这些河流中硝酸盐和亚硝酸盐无致癌作用。
