Summary: Estuaries are major sources of pollution in coastal areas, and estuarine water quality prediction models can provide early warnings to prevent disasters. This study developed machine learning models to predict NH4+-N in the Xiaoqing River estuary, China, finding a strong nonlinear relationship between estuarine NH4+-N and NH4+-N of the upper reaches. The explanations from the model highlighted the critical impact of two monitoring stations in the upper reaches on estuarine water quality.

Summary: A low-power, low-cost nitrate, phosphate, and pH sensor and sensing system have been developed for real-time water quality monitoring. The sensor is fabricated using 3D printing with carbon nanotube electrodes and polydimethylsiloxane substrate. Experimental results show that the sensor has high sensitivity to temperature, nitrate, phosphate, and pH levels, and the sensing system can accurately monitor and analyze water quality using a machine learning algorithm.

Summary: Effluent from anthropogenic activities has led to a notable impact on the environment, particularly on water quality. Various pollutants in water can be removed using physical, chemical, and biological methods, with membrane separation and adsorption techniques being more effective. Recent research has focused on the development of wastewater treatment technologies, with a recognition of the challenges in enhancing treatment methodologies for commercial application.

Summary: The research revealed that Prymnesium parvum microalgae causing harmful algal blooms in water bodies produces toxins affecting ecology and economy. The use of molecular techniques identified the presence of this microalgae in blooms causing fish kills in the UK, including detection of B-type prymnesin toxins for the first time in the area. The study suggested a correlation between blooms and rising temperatures, and demonstrated that low-dose hydrogen peroxide treatment is an effective strategy to control the spread of the algae blooms in enclosed water bodies.

Six parabens and five paraben metabolites were frequently detected in water and sediment samples, with the overall pollution level considered to be intermediate globally. The spatial distribution of chemical concentrations along the river is influenced by multiple factors, with wastewater treatment plants appearing to be a major factor.

Summary: River water in Bangladesh, crucial for domestic, agricultural, and industrial purposes, has been facing severe pollution issues for decades, especially in urban rivers such as Korotoa, Teesta, Rupsha, Pashur, and Padma. Heavy metal concentrations have exceeded drinking water standards in most rivers, leading to downstream pollution. Additionally, high metal concentrations in sediment and bioaccumulation in fish and crops highlight the urgent need for water quality management and mitigation measures in the region.
