“…Indeed, Zhang et al [29] confirmed the distinctively higher concentration in shallow depths compared with deeper parts of an aquifer. Gutiérrez et al [21] identified some of the groundwater of aquifers with NO 3ˉ contamination depending on the type of area, aquifers of semiarid, arid and hyperarid areas ( Table 1).…”

“…In fact, in the gastrointestinal tract, the ingested NO 3ˉ is reduced to NO 2ˉ that binds to hemoglobin to form methemoglobin. In the case of infants, it only takes a 10 mg/L N-NO 3ˉ to cause methemoglobinemia [21,36]. For chronic toxicity, the consumption of NO 3ˉ at levels higher than 50 ppm has been associated with (i) increased thyroid volume and subclinical thyroid disorders, (ii) increased incidence of goiter in children, (iii) carcinogenicity due to the conversion of NO 3ˉ to NO 2ˉ and formation of genotoxic/carcinogenic N-nitroso compounds, such as N-nitrosamines and N-nitrosamides, some of which are known carcinogens [23,35].…”

One of the most important challenges facing humanity today is to conserve and sustain water resources (either surface water or groundwater). This challenge became more pronounced with the increase of urban, agricultural, and industrial activities that discharge a considerable amount of wastewater. Therefore, the preservation of water sources from pollutants is a major concern, shared by all, public, industrial, scientific, researchers, and decision-makers. This chapter analyzes in more detail the pollution and pollutants caused by agricultural and industrial activities. Particular attention is given to pollution via nitrogen and heavy metals (NO 3 − , Cr(VI), and Cu(II)) in either international or national level. The effect of these pollutants on human health and environment, their standards/regulations, and the different current methods used for their detection and treatment are all discussed in the chapter.

“…Nitrate (NO 3 − ) has high mobility and can be lost from the vadose zone by leaching to groundwater because of its solubility and electronegativity (Chowdary, Rao, & Sarma, 2005). Therefore, NO 3 − is the most common pollutant found in shallow aquifers and can cause a crises in related to the drinking water supply and eutrophication of water bodies in local river systems (Gutiérrez, Biagioni, Alarcón-Herrera, & Rivas-Lucero, 2018;Schuetz, Gascuel-Odoux, Durand, & Weiler, 2016). Due to the high fertilizer application rate in modern intensive agricultural production, groundwater nitrate contamination has become a global problem (Chen, Wu, Hu, & Li, 2010;Liu, Ming, & Ankumah, 2005).…”

Estimation of baseflow nitrate loads by a recursive tracing source algorithm in a rainy agricultural watershed

Baseflow has become an important source of nitrate nonpoint source pollution in many intensive agricultural watersheds. Uncertainties in baseflow nutrient load separation are caused by the effects of hydrometeorological factors on both baseflow recession and baseflow nutrient load recession. These uncertainties have not been addressed well in the existing separating algorithms, which are based on simple baseflow rate-load relationships. In the present study, a recursive tracing source algorithm (RTSA) was developed based on a nonlinear reservoir algorithm and hydrometeorology-corrected baseflow nutrient load recession parameter. This approach was used to reduce the uncertainty of baseflow nitrate load estimation caused by variations in different load recessions under varying climate conditions. RTSA validation in a typical rainy agricultural watershed yielded Nash-Sutcliffe efficiency, root mean square error-observation standard deviation ratio, and R 2 values of 0.91, 0.30, and 0.91, respectively. The baseflow nitrate-nitrogen (N─NO 3 -) loads from 2003 to 2012 in the Changle River watershed of eastern China were estimated with the RTSA. The results indicated that baseflow nitrate export accounted for 62.0% of the mean total annual N─NO 3 loads (18.0 kg/ha). The total baseflow N─NO 3 export was highest in spring (3.6 kg/ha), followed by summer (3.2 kg/ha), winter (2.3 kg/ha), and autumn (2.1 kg/ha). The contribution of baseflow to total nitrate in the stream decreased in the order of winter (69.88%) >spring (66.59%) >autumn (60.36%) >summer (54.04%). The monthly baseflow N─NO 3 loads and flow-weighted concentrations greatly increased during the research period (Mann-Kendall test, Z s > 2.56, p < .01). Without proper countermeasures, baseflow nitrate may represent a serious long-term risk for water surfaces in the future.

Synthesis of Graphite‐Based Ion‐Imprinted Polymer for the Selective Removal of Nitrate Ions

et al. 2022

A graphite‐based ion‐imprinted polymer (G‐IIP) was synthesized using the surface‐printing technique. Allylthiourea was used as the functional monomer, nitrate as the template, and ethylene glycol dimethacrylate as a crosslinker. The polymers were characterized, and the adsorption capacity was tested. The binding ability of G‐IIP was nearly twice higher than that of the graphite‐non‐imprinted polymer (G‐NIP). The adsorption of G‐IIP followed the Freundlich isotherm and the pseudo‐second‐order kinetic. G‐IIP showed good removal efficiency of nitrate ions in actual wastewater samples with 85 % recovery. Overall, the fabricated G‐IIP would be a potential adsorbent for wastewater treatment.
