Summary: Excess heavy metal concentrations caused by severe anthropogenic activities are major threats to aquatic pollution in developing countries like Ethiopia. This study assessed the current status and spatial distributions of heavy metals in water and sediment samples of the Megech River in northern Ethiopia. The results showed that concentrations of Cu, Zn, and Cr in the water were within international guidelines, while the maximum concentrations of heavy metals in sediment were within recommended guidelines. Higher concentrations of heavy metals were observed at sites with higher anthropogenic activity, indicating the need for continuous monitoring and seasonal studies to assess the impact on downstream sections.

Summary: The study revealed that the Chenab River is being polluted due to the untreated discharge of industrial effluents and sewage runoff from the city, and these heavy metals from anthropogenic pollution load have adverse effects on the fish population in the river system.

Summary: The quality of water resources in Ethiopia is declining rapidly due to contamination from synthetic organic and inorganic compounds, chemicals, and nutrients, leading to severe environmental degradation. This study aimed to assess the pollution status of a river in the study area using physicochemical parameters and microbial environmental matrices. The results showed that the river was lightly polluted.

Summary: A study using a risk ranking approach assessed the ecotoxicological risk of 19 metals in the lower Yangtze River on aquatic wildlife, identifying iron, copper, and titanium as the most concerning substances. The risk from copper and some rarely monitored metals may have been underestimated.

Summary: The present study aimed to investigate the contamination source, level, and spatial distribution of globally alarming trace metals from Awetu watershed streams in southwestern Ethiopia. The study found that the concentration of trace elements in the streams is associated with the type of waste entering the streams and may pose a risk to downstream users. Awareness creation and establishment of waste management systems and river quality monitoring should be implemented to minimize public health risks and deterioration of the aquatic ecosystem.

Summary: This study assessed heavy metal pollution in river water during the COVID-19 pandemic and post-pandemic period. The results showed variable concentrations of heavy metals at different depths, possibly due to sinking tendencies or anthropogenic sources. However, all concentrations were within permissible limits, which may be attributed to reduced anthropogenic activities during the pandemic.

Summary: The pollution of river bottom sediments by heavy metals is a significant environmental issue resulting from human activities. A study on the Warta River in Poland showed that heavy metal pollution was heavier in 2016 compared to 2017, with lower ecological hazard in the latter year. Cluster analysis revealed distinct groups of sample collection stations with similar chemical properties, suggesting that the concentrations of heavy metals may be influenced by urbanized areas and river processes.

Summary: The study found that levels of Fe, Pb, and Mn in the water of the Nile River in the Cairo region exceeded the allowed limits, while Cu and Zn levels were within limits. In fish muscle, Fe and Cu levels were within permissible limits, but Mn, Zn, and Pb exceeded the limits. The study also highlighted the importance of monitoring heavy metal concentrations in aquatic ecosystems and the potential health risks posed by certain metals like Pb to habitual fish eaters.

Summary: Sediment quality assessment is important for evaluating the quality of rivers and this study focuses on assessing heavy metal concentration in size-fractionated sediments of River Ganga and identifying sources of contamination. The results show that the sediments are contaminated and enriched with toxic metals, with Chinyalisaur, Devaprayag, and Rishikesh being classified as pollution hotspots. Natural sources contribute to aluminum and iron, while anthropogenic sources contribute to chromium, zinc, lead, nickel, copper, and cadmium. Immediate interventions are needed to control further contamination by restricting wastewater discharge into River Ganga.

Summary: The new INCA-Metals model simulates the impact of tannery discharges on river systems, accounting for key chemical reactions and the daily behavior of metals. The model can also consider different sources of pollution and has been applied in a tannery complex in Bangladesh.

Summary: This study investigated the occurrence and characteristics of microplastics (MPs) in the surface water and sediment of the Buriganga river in Bangladesh. The results showed that MPs were widely distributed in the river, mainly in fragment form, with polypropylene (PP) being the most common polymer type. The MPs were contaminated by heavy metals and the pollution load index (PLI) indicated a higher risk level in downstream areas influenced by anthropogenic activities.

Summary: The aim of this study was to assess Cu, Zn, and Cr pollution in the Matanza-Riachuelo river in Argentina and to evaluate tolerance strategies and toxic effects in aquatic macrophytes. The results showed that the highest concentrations of heavy metals were found in the lower basin of the river, while the upper basin was mainly affected by lithogenic origin metals. Sagittaria montevidensis adapted to the polluted environment through heavy metal exclusion mechanisms, while Eichhornia crassipes exhibited tolerance through root compartmentalization.

Summary: In this study, native and transplanted aquatic moss specimens were used to assess metal contamination in a river affected by acidic and metalliferous drainage from mining areas. The analysis identified patterns of contamination in the watershed and highlighted attenuation of metal availability downstream. Differences in metal accumulation capacities between native and transplanted moss raise questions about element uptake and retention mechanisms.

Summary: A persistent foam cover has been observed in the Yamuna River near Okhla in Delhi, India for nearly two years, and it has become a matter of public concern after a gigantic appearance of foam in November 2021. The presence of detergents and phosphates as foaming agents has been highlighted as the cause of foam formation, but there are still unaccounted factors and underlying agents that need to be understood. This article outlines these factors and suggests future research directions for the dense foam formation in the Yamuna River.
