The accurate prediction of total phosphorus (TP) is crucial for the early detection water quality eutrophication. However, predicting TP concentrations among canal sites challenging due to their complex spatiotemporal dependencies. To address this issue, study proposes a GAT-Informer method based on correlations predict in Beijing–Hangzhou Grand Canal Basin Changzhou City. begins by creating feature sequences each site time lag relationship concentration between sites. It then constructs graph data combining real river distance and correlation sequences. Next, spatial features are extracted fusing node using attention (GAT) module. employs Informer network, which uses sparse mechanism extract temporal efficiently simulating model was evaluated R2, MAE, RMSE, with experimental results yielding values 0.9619, 0.1489%, 0.1999%, respectively. exhibits enhanced robustness superior predictive accuracy comparison traditional models.

Nitrate contamination in drinking water poses significant health risks, particularly rapidly urbanizing areas of developing countries. This study presents an integrated computational and graphical approach to evaluate the geochemistry risks nitrate-contaminated for six age groups Southeast, Nigeria. The research employed a detailed methodology combining nutrient pollution index (WNPI), nitrate (NPI), (WPI), geochemical plotting techniques, stoichiometry, risk computations. Water samples from several locations were analyzed physicochemical parameters concentrations. Results revealed predominantly acidic conditions varying levels contamination. Geochemical analysis indicated that silicate weathering ion exchange processes primary influences on chemistry. WPI identified 14.29% as "extremely polluted" (WPI > 1), while WNPI classified 7.14% "moderately (WNPI 1). However, NPI categorized safe, indicating low inputs anthropogenic sources. Health assessments low-moderate with highest total hazard 0.839 6-12 months group; thus, higher vulnerability infants. Oral exposure was found be dominant pathway, contributing over 99.90% risk. provides crucial insights achieving Sustainable Development Goals (SDGs) related quality public protection. offers robust framework resource management interventions risk-prone areas. Future should focus expanding spatial coverage, incorporating sensitivity analyses, exploring advanced technologies real-time monitoring predictive modeling quality.
