Health effects of nitrate concentrations in the groundwater of Al-Manara village, north-east of Mosul city, Iraq

Probabilistic Risk of Nitrates to Human Health Via Drinking Water: A Case Study of Water Supply for Dandan Station and its Quarters in Mosul, Iraq

“…The increase in the values is due to the high values of CDI, which ranged between (0.13698 -0.17110 mg/kg/d). These values are notably lower than the values reported in a prior study 22 concerning the human health risks associated with nitrates in the water sources of Al-Manara village, located to the north of Mosul city. In that study, the HI and CDI values for infants ranged between 0.4942 to 0.5432 and 0.7907 to 0.8691 mg/kg/d, respectively.…”

“…Notably, the age group (16 to 18) exhibited comparatively lower susceptibility to nitrate-related risks in comparison to other age groups, with the CDI and HI values fluctuating within the range of 0.05245 to 0.09253 mg/kg/d and 0.03278 to 0.05783, respectively. This finding is supported by Al-Bhar and Al-Saffawi's study, 22 which also identified the age group (16-18) years as the least affected by nitrate exposure. In general, the risk quotient values for the age groups were as follows: Infant > )6 to 11( > ( > 21-Females) > (18 to 21) > ( > 21-Males) > (11 to 16) > (16 to18).…”

“…This is primarily due to pressure imbalances within the pipes and the infiltration of sewage, especially in the context of the growing trend of directly connecting water pumps to the network pipes. [13][14][15][16][17][18][19][20][21][22][23][24] Figure 1 and Table 1 summarize the characteristics of the studied area.…”

“…most of which have carcinogenic and mutagenic properties, contributing to conditions such as leukemia, stomach, colon, rectal cancers, oral ulcers, and genital issues, as well as increased risks of sudden death, birth defects, and miscarriages in pregnant women. 21,22 Fortunately, the presence of ascorbic acid, polyphenols, and other compounds in high concentrations in most vegetables serves to inhibit the formation of NOC compounds, providing protection for human health against these serious diseases. 22,23 Therefore, this study aimed to estimate both the nitrate ion concentrations and the associated health risks in the drinking water supply of the Dandan water station and its connected neighborhoods on the right side of Mosul city.…”
