ABSTRACT Fluoride and nitrogen contamination is a global concern has been serious problem in agricultural areas. This study aims to identify the source of fluoride groundwater assess quality human health risks Guanzhong Plain, northwest China. The results showed that concentrations were 0.15–4.74 mg/L for F−, 0.02–89.89 NO3−-N, BDL-2.40 NH4+-N groundwater. Distinct area-dependent distributions observed region. Higher F− NO3−-N detected northern part, higher levels southern part. Water–rock interaction activities controlling factors distribution About 80% samples are considered have good water with WQI < 100. Exposure through drinking should require more attention. total non-carcinogenic oral ingestion 0.22–3.19 adults 0.51–7.44 children, respectively. order pollutants terms their hazard residents was > NO2−-N. findings this could provide insights into management.

Ecological water replenishment (EWR) changes the recharge conditions, flow fields, and physicochemical properties of regional groundwater. However, resulting impacts on mechanisms regulating sources transformation groundwater nitrate remain unclear. This study investigated how EWR influences processes using an integrated approach Water chemistry analysis stable isotopes (δ15N-NO3− δ18O-NO3−) along with microbial techniques. The results showed that resulted in a decrease NO3-N from 12.98 ± 7.39 mg/L to 7.04 8.52 mg/L. isotopic characterization suggested mainly originated sewage manure. Bayesian isotope mixing model (MixSIAR) indicated increased average contribution manure 46% 61%, whereas chemical fertilizer decreased 43% 21%. exacerbated impact nitrate. Microbial community revealed substantial relative abundance Pseudomonas spp. 13.7% 0.6%. Both weakened denitrification enhanced nitrification effectiveness techniques for delineating transformations influenced by EWR.
