Abstract Human activities and climate change threaten water quality in China’s rivers. We simulated the monthly concentrations of riverine total nitrogen (TN), ammonia-nitrogen (NH 3 -N), phosphorus (TP), chemical oxygen demand (COD Mn ) 613 sub-watersheds nation’s 10 major river basins during 1980–2050 period based on a 16-year (2003–2018) monitoring dataset using stacking machine-learning models. The results showed that improved markedly, except for TN concentration, which was probably due...
Abstract Nutrients such as phosphorus and nitrogen lead to extensive growth of harmful algae in lakes reservoirs, which results eutrophication. The driving mechanism primary productivity change reservoirs at a wide spatial temporal scale remains largely unknown. We establish water quality database using stacking machine learning model, including monthly chlorophyll‐a (Chl‐a), total (TN) (TP) concentrations 255 332 from 1980 2018. find an increase the number risk algal blooms, with...
Abstract Background Risks of adverse ecological effects copper (Cu) consider water quality parameters were not fully understood in China. Here, a national-scale exposure Cu Chinese surface was investigated, and the first report using multiple linear regression approach to predict correct toxicity data based on chemistries Risk overestimated without considering previous studies. Results Under prevalent conditions hardness = 150.0 mg/L, pH 7.8, dissolved organic carbon (DOC) 3.0 across China,...
Abstract A comprehensive and accurate estimation of water quality in lakes reservoirs is vital for the protection aquatic biota. Research on spatiotemporal variations nitrogen (N) phosphorus (P) concentrations lacustrine systems typically plagued, however, by a lack long‐term, spatially continuous monitoring data. This paper assembled 30‐year (1989–2018) data set 586 China, along with basin characteristics climate conditions, forming available. These were then used stacking model (based...

Abstract Background Risks of adverse ecological effects copper (Cu) conditions water quality parameters were not fully understood in China. Here, a multiple linear regression approach was employed to assess risks posed by Cu under various quality. Results the compared assessments Chinese surface waters that did consider might affect availability Cu. Under prevalent hardness = 150.0 mg/L, pH 7.8, and DOC 3.0 across China, predicted no effect concentration for total, dissolved 9.71 µg/L. Based...
