“…Trace element concentration data produced in the study are accessible in the Electronic Data file and the Hydroshare data repository (Bridgestock et al, 2022). Interquartile ranges of elemental concentrations in the studied catchments largely agree with, or are lower than, average values from a global compilation of large rivers catchments thought to be unperturbed by anthropogenic activities (Fig.…”

“…El Niño events are responsible for a decrease in rainfall, while La Niña increases rainfall [41]. The climate system in the region is a major factor affecting hydrology, which plays a significant role in ecosystems and society [23,42,43]. For topography, the Mekong River starts from the Tibetan Plateau at 4500 m and flows out to the South China Seas through the Mekong Delta with 14,500 m 3 /s of mean annual discharge and 4800 km of length [32,44,45].…”

“…The Irrawaddy River starts from the Himalayan Mountains and flows out to the Andaman Sea through the Irrawaddy Delta with 13,000 m 3 /s of mean annual discharge and 2170 km of length [33,42]. The Salween River originates at the Tibetan Plateau and flows out to the Gulf of Martaban through the Salween Delta with 210 km 3 /year of average annual discharge and 3200 km of length [21,43]. For the upstream areas of the three basins, snowmelts serve as the major water source [43,46], while precipitation and groundwater are also the major water sources [42,46].…”

Determination of Spatial Pattern of Environmental Consequences of Dams in Watersheds

Many hydro-dams have been built for beneficial gains, but they are causing numerous unintended negative effects on the environment. The complexity of dam impacts and the insufficient knowledge of developing countries result in many uncertainties in managing land systems and environmental impact assessments (EIAs). Also, considering the consequences beyond the dam sites proved challenging in EIAs. In this context, this paper aims to determine the spatial pattern of the environmental consequences of dams, quantify the distance of impacts, and identify different patterns in both upstream and downstream areas. We considered the hydrological linkage of dams with wetlands in watersheds and the spatial relationship between watersheds to explicate the spatial pattern. Two hundred and ninety wetlands in the Mekong, Salween, and Irrawaddy Basins were categorized into those linked with dams and those without dams, and the hydrological characteristics were statistically compared for two periods (before and after the dam booms) using the Mann–Whitney U test. The watersheds having significant differences were found, and their spatial relationship in terms of location (i.e., upstream and downstream) and distance was determined by utilizing the HydroBASINS’ Pfafstetter coding system. The results indicate that the impacts of dams on downstream areas extend significantly farther than their effects on upstream regions in HydroBASINS level-7 representation. The quantitatively determined spatial patterns on upstream and downstream areas can provide accurate spatial baseline information in land system management and EIA.

“…In order to evaluate the potential risk and effect of Li contamination on the aquatic life of rivers, it is essential to first determine the characteristic Li concentration values in the river waters. Depending on the geochemical composition of the bedrock and weathering processes in the catchment area, the meteorological conditions, and the natural and anthropogenic contaminants of tributaries, the dissolved Li concentration in rivers varies widely (0.36–454 µg/L) 42 – 47 .…”

Due to increased manufacture and recycling of lithium batteries across the world, we may anticipate a rise in lithium pollution in the aquatic environment and drinking water reservoirs. In order to investigate the current status regarding the lithium content in Hungarian tap waters, samples were collected from the public drinking water supply systems of 19 county seats in Hungary during seasonally selected times. Depending on the water sources, such as bank-filtrated river water, surface water from open reservoirs, and groundwater, the lithium concentrations varied between 0.90–4.23, 2.12–11.7 and 1.11–31.4 µg/L, respectively, while the median values were 3.52, 5.02 and 8.55 µg/L, respectively. The lithium concentration in the bottled Hungarian mineral waters was also determined since the daily intake of lithium can be influenced by the consumption of mineral waters. The concentrations ranged from 4.2 to 209 µg/L, while the median value was only 17.8 µg/L. Additionally, a correlation was only found between lithium and potassium concentrations. The lithium concentration was also assessed at ten sampling locations in the Hungarian segment of the Danube River since the Danube water is also a water source for additional drinking water utilities using bank filtration technology. The mean and median lithium concentrations were 2.78 and 2.64 µg/L, respectively.
