Article Synopsis
- High concentrations of harmful metal(loid)s and extreme acidity in acidic pit lakes pose environmental challenges, which the study focuses on using Cueva de la Mora in Spain as a case study.
- The research investigates bioremediation strategies, particularly by stimulating sulfate reduction in the lake's deep layer to create low-solubility sulfide minerals, employing various amendments like glycerol and elemental sulfur.
- Results indicated that glycerol significantly enhances sulfate reduction and the combination of glycerol with elemental sulfur leads to the highest sulfide production, highlighting the importance of electron donors and acceptors for successful bioremediation.
Microplastics are small plastic particles with sizes ranging between 1 μm and 5 mm. Microplastics can originate from macro plastics and degrade to a smaller size or be produced directly by manufacturers. Few studies have examined microplastic contamination in freshwater sediment cores to estimate changes in microplastic contamination over time.

- Produced water from oil and gas wells can be used to reduce dust on unpaved roads, but it can also contain harmful pollutants.
- A study found that while produced water reduced dust by 10-85% in high humidity, commercial dust control products were generally more effective, reducing dust by over 90%.
- When it rains, roads treated with produced water could pollute water runoff more than those treated with commercial products, especially with harmful substances like sodium and radium.
Across the United States, road palliatives are applied to roads for maintenance operations that improve road safety. In the winter, solid rock salts and brine solutions are used to reduce the accumulation of snow and ice, while in the summer, dust suppressants are used to minimize fugitive dust emissions. Many of these products are chloride-based salts that have been linked to freshwater salinization, toxicity to aquatic organisms, and damage to infrastructure.
