“…RBC possesses a favorable conservation status without agricultural activities, which may have contributed to the soil fertility at this site. Soil fertility can be an important indicator of forest recovery for plant communities affected by tailings (Ferreira et al 2021;Fortes et al 2022). Our results revealed that the V% in the soil was the primary driver in scrub restinga areas, suggesting that V% could serve as a crucial indicator for the recovery of plant communities affected by the tailings.…”

“…The primary origin of salt spray is commonly attributed to the bursting of bubbles in breaking waves, often recognized as a crucial factor influencing vegetation zonation in coastal dunes (Du and Hesp 2020). The collapse of the dam resulted in the dispersion of sediments from the Doce River over a vast area along the coast, covering hundreds of kilometers, which was primarily caused by the effects of the salt spray (Marta-Almeida et al 2016;Duarte et al 2021;Fortes et al 2022). The primary factor responsible for the southward dispersion of the salt spray was the wind, which is a predictable occurrence in this region due to the seasonal variability in wind direction, with a predominance towards the south during the austral spring and summer (Marta-Almeida et al 2016).…”

In 2015, a breach in the Fundão Dam in Mariana (Minas Gerais State, Brazil) resulted in the release of contaminated tailings into the Doce River basin. This accident increased the concentrations of arsenic (As), lead (Pb), cadmium (Cd), vanadium (V), and manganese (Mn) in the soil, posing a potential hazard to the physiology of native species. Therefore, this study aimed to assess whether chlorophyll a fluorescence (ChlF) in Allagoptera arenaria and Guapira pernambucensis changed following this accident when tested under different precipitation regimes in relation to soil properties, and heavy metal absorption. Our research was conducted in the Environmental Protection Area of Conceição da Barra (APA) and the Comboios Biological Reserve (RBC) located in the state of Espírito Santo, Brazil, south-eastern Brazil. Five independent biological replicates of A. arenaria and G. pernambucensis were selected at each site for nutritional and chlorophyll a fluorescence analysis. Soil samples from APA and RBC had similar metal concentrations and physical properties. Five years after the dam rupture, A. arenaria had absorbed As, Pb, and V. The increased amounts of heavy metals absorbed did not significantly impair the OJIP curve configuration in both species during the evaluated periods. However, A. arenaria at RBC during the rainy season showed increases in the values of φR0, φP0, PITOTAL, and φE0. Cluster analysis indicated that ChlF in both species was more sensitive to variations in heavy metals within plant tissues. Then, ChlF variation indicated that A. arenaria and G. pernambucensis exhibited an acclimation strategy in response to increased absorption of heavy metals.

“…Although progress has been made on issues related to the implementation of a monitoring and early warning system to study the physical and chemical stability of TSFs, knowledge gaps remain in the mining sector concerning how to provide quality, reliable, real-time information to mining companies, communities, and authorities through an intuitive, stable platform to avoid the risks of failure and socio-environmental harm [105][106][107]. This must be addressed in the coming years to strengthen operational management, promote a culture of risk reduction, and improve communication between the responsible parties and emergency responders [108,109].…”

The recent tailings storage facility (TSF) dam failures recorded around the world have concerned society in general, forcing the mining industry to improve its operating standards, invest greater economic resources, and implement the best available technologies (BATs) to control TSFs for safety purposes and avoid spills, accidents, and collapses. In this context, and as the era of digitalization and Industry 4.0 continues, monitoring technologies based on sensors have become increasingly common in the mining industry. This article studies the state of the art of implementing sensor technologies to monitor structural health and safety management issues in TSFs, highlighting advances and experiences through a review of the scientific literature on the topic. The methodology applied in this article adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and utilizes scientific maps for data visualization. To do so, three steps were implemented: (i) a quantitative bibliometric analysis, (ii) a qualitative systematic review of the literature, and (iii) a mixed review to integrate the findings from (i) and (ii). As a result, this article presents the main advances, gaps, and future trends regarding the main characteristics of the sensor technologies applied to monitor TSF structural health and safety management in the era of digitalization. According to the results, the existing research predominantly investigates certain TSF sensor technologies, such as wireless real-time monitoring, remote sensors (RS), unmanned aerial vehicles (UAVs), unmanned survey vessels (USVs), artificial intelligence (AI), cloud computing (CC), and Internet of Things (IoT) approaches, among others. These technologies stand out for their potential to improve the safety management monitoring of mine tailings, which is particularly significant in the context of climate change-related hazards, and to reduce the risk of TSF failures. They are recognized as emerging smart mining solutions with reliable, simple, scalable, secure, and competitive characteristics.
