“…En ese sentido, como enfatiza Zhang et al, para la movilidad de estos metales pesados o sustancias nocivas, los ríos son los principales medios de transporte hacia las áreas costeras, ya que los materiales son arrastrados desde la cuenca alta influenciada por la temporada de lluvias [44], [45]. En efecto, el nivel de los metales es más alto en tramos inferiores por sedimentación y otros efluentes perniciosos [46], lo que afecta continuamente la calidad del agua desde las locaciones mineras en Casapalca hasta la aglomeración urbana de Lima-Callao.…”

The urban agglomeration of Lima and Callao is the second largest city in the world located in a desert, and its supply depends on three small rivers, the Rímac River being the one with the greatest water supply, affected by contamination by mining tailings, sewage and Solid waste. In order to know the climatological and hydrographic conditions that favor the concentration of heavy metals in the water, the relationship between rainfall, water discharges and concentration of aluminum, cadmium, iron and lead in the Rímac River hydrographic system in the period 2018 -2021. For which data processing was carried out from six meteorological stations, a water quality monitoring point and four limnimetric stations, through dynamic tables. As a result, it was found that the concentration of heavy metals is higher in the lower basin when rainfall and river level increase in localities of the Alto Rímac sub-basin, which presents intense mining activity, unlike the Santa Eulalia sub-basin. river where there are no large-scale mining operations, whose records present weaker relationships with the concentration of heavy metals. In conclusion, the highest concentration of heavy metals in the lower basin occurs during the months with the most intense rains in the headwaters of the basin, as the dragging capacity increases during the flooding of rivers and streams, allowing concentrations to exceed up to 120 times the quality standards for the production of drinking water.

“…Pollutants that infiltrate into stream sediments can easily be transferred to aquatic living species and subsequently to the human body via the food chain, posing major health risks [11][12][13]. The harmful elements contained in stream sediments mostly originate from tailing ponds and waste dumps left over after the shutdown of mining operations [6,[14][15][16]. Toxic metal emissions from mining activities can contaminate surface water, groundwater, agricultural soils, and food crops, causing health dangers to the population via a variety of pathways including the mouth (with food and drinking water or from the soil or sediments to the mouth via the hands), respiratory tract, and skin [17,18].…”

Sediment samples from the Săsar River and its main tributaries were analyzed for their potentially toxic elements at the site of the Romplumb metallurgical company and near the well-known Pb-Zn-Cu epithermal deposit of Baia Sprie located in the Neogene volcanic chain of the Eastern Carpathians, Romania. The average metal concentrations arranged in order of decreasing abundance are as follows (mg·kg−1): Mn (4098) > Zn (2093) > Pb (918) > Cu (489) > As (160) > Cr (37.51) > Ni (30.25) > Co (28.13) > Cd (9.72) > Hg (1.81). Several pollution indices were successfully used to assess the degree of contamination and ecological risk. The majority of sampling sites indicate high degrees of pollution, with two major hotspots identified. There are further sources, such as the Șuior (Pb-Zn-Au) and Săsar (Au-Ag) epithermal deposits, Cuprom company, and Bozânta tailing ponds, identified as contaminants. The Baia Mare mining district is causing a serious threat to the aquatic systems in the region, and it can be taken as a reference area for the human impact derived from the mining of mineral deposits of Au-Ag-Cu-Pb-Zn. It is imperative to reduce ecological risks and thereby protect the population living within this abandoned mining area.

“…The studies previously conducted on the Teesta River (Bangladesh) were mostly concentrated on the radiological influences of radionuclides and on rare earth materials, 14 ecological settings, 15 temporal changes in physiochemical parameters, 16 land use and land cover modelling, 17 flood risk evaluation, 18 and prediction of spatiotemporal changes in channel morphology. 19 Moreover, the pollution index assessment of sediment quality has been studied on the Indian portion of the Teesta River 20 but the repercussions of disintegrated trace elements from geogenic provenance is one of the pioneer studies on the rivers of northern Bangladesh.…”
