“…Fifteen samples had high contents of Na + (>200 mg/L) exceeding the permissible limit of the WHO standard. Excessive Na + above the maximum permissible limit can cause adverse health risks such as hypertension and vomiting [19,22]. The concentration of K + in groundwater was generally quite lower than Ca 2+ , Mg 2+ , Na + .…”

“…The unusual increment in Cl − concentration is probably linked to the joint effect of both halite dissolution and anthropogenic pollution. Nitrate contamination in phreatic water has been a growing concern to hydrogeologists and practitioners over the world [22,23]. In the study area, a large quantity of chemical fertilizers were used by farmers to ensure better crop yields because agricultural cultivation is usually the principal economic source for local residents.…”

“…As per classification nitrate [22], six samples belong to high risk and nine samples come under very high health risk category. Additionally, some trace elements are essential for human health, but their long-term accumulation in groundwater may also pose potential threats to ecological security and human health [24].…”

Groundwater resources are playing an increasingly vital role in water supply for domestic and irrigation purposes in the Yinchuan Plain, along with the reduction in water transfer from the Yellow River. This study aimed to identify the current status of phreatic water quality and associated hydrogeochemical processes in an irrigated region along the upper Yellow River. A total of 78 water samples were collected in September 2018 for chemical analysis. Results showed that the phreatic water was excellent or good in most areas west of the Yellow River, while it was poor or very poor quality in some places east of the Yellow River. The nitrate contamination is particularly severe in the pluvial-alluvial plain, relating to the localized fine-grained zone with low permeability. Most samples had no sodium hazard but had magnesium hazard. Additionally, the overall evolutionary trend of the phreatic water showed the transformation of Ca-Mg-HCO 3 into Na-Cl-SO 4 type. Rock weathering and evaporation jointly predominate the evolution of phreatic water chemistry. The main geochemical processes involve the dissolution/precipitation of gypsum, halite, dolomite. and calcite, along with the cation exchange. Insights from this work have important implications for groundwater sustainable management in such irrigated regions along the upper Yellow River.

“…Based on the C EXP value and adult drinking water intake, formula (2, 3) was used to calculate adult nitrate intake. The hazard quotient (HQ) is further calculated using formula (4,5,6). The results are shown in Table 5.…”

“…Drinking water of groundwater is an important source of nitrate. There are many sources of groundwater nitrate, such as improper disposal of waste, waste from animal farms [5], use of nitrogenous fertilizers, [6] vegetables (such as Chinese cabbage, kale and carrots), etc. Early studies have shown that nitrate pollution in groundwater may originate from several different sources, including point source pollution (such as industrial pollution and intensive animal husbandry) and non-point source pollution (such as fertilizers, fungicides, atmospheric deposition, etc.)…”

Background: Nitrate is one of the most common chemical contaminants of groundwater, and it is an important unqualified factor of rural groundwater in Yantai. In order to assess the risk of exposure to drinking water nitrate for adults and juveniles, in recent years, we monitored the nitrate concentrations in rural drinking water,a model was also used to assess the human health risk of nitrate pollution in groundwater. Methods: From the year 2015 to 2018, the drinking water in rural areas of Yantai was tested according to the "Sanitary Standard for Drinking Water" (GB5749-2006). The principal component analysis was used to analyze the relationship between groundwater chemicals and nitrate. The model was used to assess human health risks of groundwater nitrate through the drinking water and skin contact. Results: A total of 2348 samples were tested during the year 2015-2018.Nitrate and total dissolved solids, total hardness, chloride are all relevant, the above indicators may come from the same source of pollution; The median nitrate content (C EXP50) was 17.8 mg / L; the risk of exposure in each group was ranked as: Juveniles > Adult female > Adult male;the median health risk (HQ 50) for minors and adults exceed 1. Conclusions: The concentrations of nitrate is stable and does not change over time. The high concentration of nitrate in rural areas of Yantai may be the result of the interaction of fertilizers and geological factors. The risk of exposure to nitrate in juveniles and adults is above the limit, so it is necessary to be on the alert for the high levels of nitrate.
