“…Furthermore, examples of terrestrial ora and fauna were lost, with the destruction of areas within the Atlantic Forest biome. The aquatic biota was severely impacted, with the death of thousands of sh, as well as the extinction of endemic species (Miranda;Marques, 2016;Caldas, 2017;Girotto et al, 2020;Martins;Takahashi, 2022).…”

The collapse of Samarco mining company's tailings dam in November 2015 is recorded as the most severe environmental calamity to ever occur in Brazil. The ensuing toxic sludge devastated towns along the Doce River, leaving an enduring legacy of socio-environmental and economic destruction. The Doce River basin continues to bear the scars of this disaster to this day. This study thus proposes to investigate the bioremediation potential of three Pleurotusspp. strains, assessing their physical-chemical parameters of pH and turbidity, as well as the ability of the tested isolates to eliminate toxic metals in solution, based on water samples collected in 2015 and 2018. The studied fungal strains tended to acidify the medium, lowering the pH of the samples. In raw water, these strains effectively removed turbidity, achieving a decline of 86.2-95.0% and 28.1-40.7% in the first and second collections, respectively. High concentrations of aluminum, arsenic, barium, lead, iron, and manganese were detected in the Doce River water samples through Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Batch system experiments showed that Pleurotus spp. could efficiently remove toxic metals from the solution in seven days of incubation, with average elimination rates ranging from 94.0-99.1% and 70.3-99.0% for the six evaluated elements in the 2015 and 2018 samples, respectively. Therefore, the findings suggest that the genus Pleurotusholds significant biotechnological promise for the bioremediation of contaminated or deteriorated waters.

“…Excessive intake of Al 3+ causes serious damage to the central nervous system and increases the risk of Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS) [3][4][5][6]. Based on this effect, the World Health Organization (WHO) has stipulated that the average daily intake of Al 3+ (aluminium ion) is $0-0.6 mg/kg [7][8][9]. Therefore, the accurate detection of Al 3+ content is of great value for early detection, early diagnosis, and early treatment of some clinical diseases.…”

We developed a facile strategy for the fabrication of red fluorescent carbon nanodots (R‐CDs) and demonstrated their applications for Al3+ sensing. Red‐emission carbon dots (CDs) were synthesized using a simple hydrothermal treatment with citric acid and urea as precursors, manifesting intriguing red‐emission behaviour at 610 nm. With increasing Al3+ concentration, the fluorescence band at 610 nm decreased gradually. Monitoring the intrinsic fluorescence variation (I610nm), as‐prepared CDs were developed as an effective platform for fluorescent Al3+ sensing, with a linear range of 0.5–60.0 μM and a detection limit of 3.0 nM. More importantly, R‐CDs have been applied successfully to the analysis of Al3+ in actual samples with satisfactory recoveries in the range 97.12–102.05%, which indicated that obtained CDs could be implemented as an effective tool for the identification and detection of Al3+ in actual samples.
