“…Metals are of particular concern in estuarine ecosystems because they tend to adsorb to particulate organic matter, soil, and sediment particles (Tjahjono et al 2018). Accumulated metals can be released into the water column by physical, chemical, and biological processes resulting in recurrent biological contamination over time and therefore in toxic effects to the biota (Gati et al 2016; Machado et al 2016).…”

The rupture of a mining dam in southeastern Brazil in 2015 was the country's greatest environmental tragedy. In order to evaluate the ecological risks of the mine tailings on the Rio Doce estuary, this study assessed trace metal contamination and sediment quality indices up to 2.9 y after the dam rupture. Surface sediments were collected from 17 stations on the Rio Doce estuary and Cd, Pb, Cr, Zn, Cu, and As concentrations were determined by inductively coupled plasma atomic emission spectroscopy (ICP‐OES). Four ecological risk indices (modified contamination degree [mCd], pollution load index [PLI], risk index [RI], and sediment quality guideline quotient [SQG‐Q]) suggest a high risk by metal contamination with possible adverse biological effects, with moderate seasonal variability. Based on a precautionary approach, our results support fisheries closures and the need for public health monitoring in the affected areas, and support other studies that suggest chronic metal contamination of the Rio Doce estuary.

“…The NPI that allows the assessment of the overall degree of pollution was developed by Nemerow and Sumitomo (1970) and has been widely used by hydrologists Ihya et al (2018), Tjahjono et al (2018), and Anyanwu and Ukaegbu (2019) for diverse purposes and standards.

In the past two decades, freshwater bodies and their water quality have deteriorated rapidly due to several natural and anthropogenic causes, as well as rapid urbanization and industrialization. Using environmental assessment tools, eight sampling stations were used to assess the water quality of the upper Ganga and its major headstreams between January 2019 and December 2021 and to assess the impact of human-led activities on the environment and the suitability of the catchment basin to perpetuate aquatic ecological diversity. During the current study period, water quality indices such as the Water Quality Index (WQI), Nemerow Pollution Index (NPI), and the Overall index of pollution (OIP) were employed to assess water quality. Twelve physicochemical parameters were examined using appropriate techniques and then compared to international standards. A small increase was observed in some physicochemical parameters, such as pH, Turbidity, Dissolved Oxygen, and Biological Oxygen Demand, at sampling stations 7 and 8. In the upper Ganga basin, all three indices (WQI, NPI, and OIP) accurately recorded numerous natural and human events at the selected sample sites. The water quality demonstrated that aquatic species were abundant. The water quality at some sample stations was also

“…Quando essa lama de rejeito se encontra com as bacias hidrográficas, os contaminantes presentes tendem a acumular nos leitos dos rios e nos sedimentos estuarinos e oceânicos (Hatje et al, 2017). Uma vez o rejeito sedimentado, este material tóxico pode novamente suspender-se na coluna da água através de perturbaçõescorrentes marítimas, movimentação das marés, tempestades, bioturbação e atividades antrópicasresultando em recorrentes contaminações de longo prazo por metais pesados (Tjahjono et al, 2018;Mahiques et al, 2014;Fields, 2001;Simón et al, 2001;Gati et al 2016;Machado et al, 2016;Queiroz et al, 2018Queiroz et al, , 2022Barcellos et al, 2022).…”
