“…The results showed that the soils nearer to the fly ash dumpsite (0.5–1 km) in either wind direction were considerably contaminated by Cr and Cu. According to Bakshi and Panigrahi (2022), copper and chromium have higher sorption capacity, the studies have proven that Cu elements are highly contained in dry soil with high organic carbon. On the leeward transect especially in areas nearer to the dumpsite, the contamination factor of Cu was higher, and so was the total concentration of copper, due to its high sorption characteristic it could be explained that the Cu element from finer fly ash particles was easily carried by wind and deposited on soils in this area.…”

Arsenic, chromium, copper, lead, and zinc concentrations were measured in the leeward and windward directions within 40 km of the Morupule power station to assess the long‐term effects of fly ash deposition on the hazardous metal contamination of soils. Based on the quantities of these metals in the soil, the contamination factor, pollution load index, and potential ecological risk index were calculated to determine the potential of these metals will harm the ecosystem and human health. The results showed that areas (0.1–2 km) nearer to the dumpsite, especially in the leeward direction had higher contamination factors, 3.08–3.51 for Cr, 4.28–5.18 for Cu, and 3.10–3.17 for Pb. On the same distance, along the windward direction, the average contamination factor was 1.17× for Cr, 1.31× for Cu, and 1.7×x for Pb, less than that of the leeward direction. On the other hand, the potential ecological risk index was low for all the toxic metals being less than 40 index value independent of the wind direction. Similarly, the comprehensive ecological risk of various toxic metals indicated that the study area had a low ecological exposure as the index value was below 150. Overall, the toxic metal contamination in the soil due to the contamination factor is moderately polluted to unpolluted, especially on the leeward side, and the ecological risk of contamination is low across the study area, but continuous deposition of fly ash without proper management will increase the ecological risk.

“…Microorganisms eliminate heavy metals through enzymecatalysed metabolic pathways for toxic substance degradation, transforming them into carbon dioxide, methane, water, and biomass [24]. A wide range of microorganisms, bacteria [25], algae [26], fungi [27], and phyto species [28] have already been identified and isolated for potential heavy metal bioremediation and wastewater treatment.…”

Tanning, crucial for leather production, relies heavily on chromium yet poses risks due to chromium’s oxidative conversion, leading to significant wastewater and solid waste generation. Physico-chemical methods are typically used for heavy metal removal, but they have drawbacks, prompting interest in eco-friendly biological remediation techniques like biosorption, bioaccumulation, and biotransformation. The EU Directive (2018/850) mandates alternatives to landfilling or incineration for industrial textile waste management, highlighting the importance of environmentally conscious practices for leather products’ end-of-life management, with composting being the most researched and viable option. This study aimed to isolate microorganisms from tannery wastewater and identify those responsible for different types of tanned leather biodegradation. Bacterial shifts during leather biodegradation were observed using a leather biodegradation assay (ISO 20136) with tannery and municipal wastewater as the inoculum. Over 10,000 bacterial species were identified in all analysed samples, with 7 bacterial strains isolated from tannery wastewaters. Identification of bacterial genera like Acinetobacter, Brevundimonas, and Mycolicibacterium provides insights into potential microbial candidates for enhancing leather biodegradability, wastewater treatment, and heavy metal bioremediation in industrial applications.

“…Cr 3+ is a crucial element involved in lipid, carbohydrate, and protein metabolism [6]. Upon entering cells, Cr 6+ undergoes reduction by cellular reductants, leading to the production of reactive oxygen species (ROS) and ultimately resulting in oxidative stress damage, genotoxicity, and cytotoxicity in organisms [7,8]. Numerous studies have been conducted on its long-term exposure, which is harmful to aquatic animals, including the freshwater water flea Daphnia magna, Channa punctatus, and Labeo rohita [9][10][11].…”

Fish in aquatic ecosystems are often impacted by environmental stressors like temperature fluctuations and exposure to heavy metals. Chromium (Cr6+) is a known environmental pollutant that poses a threat to aquatic life. Various environmental factors, such as water temperature, have been found to affect the toxicity of dissolved chemicals in aquatic ecosystems. We investigated the toxicity of combinations of different concentrations of hexavalent chromium (Cr6+) with high temperatures in fish. Hematological indices demonstrated changes in white blood cells (WBCs), hematocrit (HCT), red blood cells (RBCs), and hemoglobin (Hb) levels during the exposure. The qualitative and semi-quantitative analyses of different tissues confirmed that higher concentrations of Cr6+ caused more significant damage than lower concentrations, with evident alterations observed in circulatory and regressive aspects. Furthermore, brain acetylcholinesterase levels decreased in both single heavy metal exposure and combined exposure at a high temperature. The activity of antioxidant oxidase and immunological parameters increased in all treatment groups compared with the control group following long-term exposure. A significant and increased effect of Cr6+ in the high-temperature groups was observed on the evaluated biomarkers, suggesting a possible synergistic effect between Cr6+ and increased temperature. The integrated biomarker response (IBR) reported the highest level of stress at 10 mg/L Cr6+ combined with high temperature. The IBR analysis revealed that the highest activity of response enzymes, such as acid phosphatase (ACP), superoxide dismutase (SOD), and glutathione S-transferases (GST), was observed in the liver, whereas the gills displayed alkaline phosphatase (ALP), GST, and SOD activity, and the kidneys demonstrated SOD, ACP, and aspartate aminotransferase (AST) to be most active. Through histopathology, antioxidant enzymes, and metabolism- and immunity-related enzymes, we determined that high temperatures enhance the potential toxicity of Cr6+ in fish. We recommend conducting a thorough assessment of the impact of climate change, particularly temperature fluctuations, when studying the toxic effects of metal pollution, like chromium, in aquatic ecosystems.
