“…Furthermore, sediments from the DRB collected 4 years after the dam rupture caused adverse effects on fish embryos (Yamamoto, Eufrásio et al, 2022). A wider study conducted in fishes collected along the DRB concluded that, for different trophic groups, fish showed bioaccumulation and physiological and histopathological effects, evidencing chronic contamination (C. E. D. Vieira et al, 2022).…”

“…The immediate effects included alterations of benthic communities, as many species were rapidly eliminated or had reduced population density, and the surviving organisms were permanently exposed to high concentrations of metals (Duarte et al, 2021). As a result, the organisms from DRB showed tissue, physiological, and cellular damage (Bernardino et al, 2019; F. Gabriel et al, 2021; Passos et al, 2020; C. E. D. Vieira et al, 2022).…”

The rupture of the Fundão dam in Brazil released tons of mining tailings into the Doce River Basin (DRB). This investigation aimed to determine the bioaccumulation of metals in soft tissues of the bivalve Corbicula fluminea exposed to sediments collected in the DRB in four periods (just after, 1, 3, and 3.5 years after the dam rupture). In the exposure bioassays, the concentrations of Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn in sediments and bivalve soft tissues were quantified. The concentration of some elements (As, Cd, Mn, and Al) in sediments exceeded the federal limits or regional backgrounds at some sampling sites, but their concentrations tended to decrease over time. However, higher concentrations of many elements were detected in the winter of 2019. Several elements were detected in C. fluminea soft tissues, but the bioaccumulation factors were generally low or not related to those elements associated with the ore tailings, evidencing that the bioavailability of metals to bivalves, in laboratory conditions, was limited.

“…In relation to other species, Mn showed a discrepancy with other marine fish species (Table 3 ). Due to the critical role of Mn in fish metabolism, it is immediately absorbed due to its involvement in gill metallothionein levels, oxidative protein damage in liver and muscle, and gill activity of superoxide dismutase; it is influenced by the trophic level and feeding habit of the species 84 .…”

The Navachiste complex (NAV) is impacted by neighbored human activities and is located in the southwestern coastal zone of the Gulf of California. The study determines the trace metal (TM) and organochlorine pesticides (OCP) health risk content in the edible tissue of Sphoeroides spp. from NAV. The daily intakes (EDI), target hazard quotient (THQ), hazard index (HI), and carcinogenic and non-carcinogenic risks were calculated. Twenty OCP and seven TM were detected. Cd, Cu, Fe, Mn, Pb, and Zn were above MRLs. The γ‒Chlordane was the most frequent OCP. The highest average concentration was for α‒HCH, followed by γ‒chlordane. With the high ratios of γ‒HCH, p, p′‒ DDD and p, p′‒DDD, and the absence of p, p′‒ DDT, the higher ratios for dieldrin and endrin than for aldrin, α‒ chlordane, γ‒chlordane, heptachlor, and heptachlor epoxide indicates historical contamination. In contrast, the residual products of methoxychlor, endosulfan, and its isomers indicate endosulfan's recent use. The TM EDI, THQ > 1 (at 120 g day−1), and the ILCR (> 1 × 10–6) were above minimum levels, showing a high-risk potential for cancer development in the long term.

“…The breach of the dam and subsequent release of mine tailings impacted freshwater, coastal, and marine ecosystems through water, sediment, and biota (COSTA, et al, 2022) Polluted water downstream of the dam breach had negative repercussions for aquatic food webs. Suspended particulate matter contained high concentrations of heavy metals which biomagnified up the food chain from plankton to macroinvertebrates and fish (VIEIRA et al, 2022). These changes continue to cause long term trophic depletion as sediments are resuspended seasonally (ANDRADES et al, 2021).…”

“…Over five years after the disaster, Vieira et al, (2022) determined that fish had been altered physiologically due to exposure to heavy metals. Physiological alterations to fish included DNA damage, lipid peroxidation, oxidative damage in proteins, metallothionein concentrations and activity of superoxide dismutase in the gills.…”

Resilience in the face of disaster: analyzing the transformation of the social ecological system of the Quilombola Community of Degredo after the Fundão dam failure

On November 5, 2015, the Fundão dam, which belonged to the mining company Samarco in Minas Gerais, Brazil, ruptured and released toxic mine tailings that flowed 660 kilometers down the Doce River. The mine tailings destroyed settlements and local environments down the river, eventually reaching the Atlantic Ocean. The remnant quilombo community of Degredo which borders the Doce River and the Ocean, is a complex socio-ecological system that was directly impacted by the disaster. The theoretical framework of Elinor Ostrom (2009) was used to analyze the impacts of the disaster on the social, ecological, economic, political, and governmental issues that occurred in this community after the disaster. Sociological factors of the community’s way of life before and after the disaster were analyzed, as well as a biophysical characteristics of the environment impacted by the spill. We also evaluated the subsistence fishery and human health effects, as well as which legal and restorative measures were taken by the responsible bodies for the disaster. The impacts included losses in the community ancestral way of life and local customs, decimation of the fishery and local ecosystems, and lasting negative human health impacts.
