Summary
Researchers developed new microplastic additive formulations to enhance microalgae carbon fixation and sedimentation in lakes. Specific decabromodiphenyl oxide (DBDPO) derivatives show promise as eco-friendly alternatives, improving these processes by over 25%.
Area of Science:
- Environmental Science
- Ecotoxicology
- Biogeochemistry
Background:
- Microplastics in lake water pose risks to microalgae carbon fixation and sedimentation.
- Decabromodiphenyl oxide (DBDPO) is a key additive influencing these processes.
- Developing effective mitigation strategies is crucial for lake ecosystem health.
Purpose of the Study:
- To design microplastic additive proportioning schemes for enhanced microalgae carbon fixation and sedimentation.
- To identify environmentally friendly alternatives to DBDPO.
- To provide theoretical support for sustainable lake ecosystem management.
Main Methods:
- Molecular dynamic simulation was employed to design additive schemes.
- CiteSpace visual analysis guided molecular modification of DBDPO.
- Screening of 12 DBDPO derivatives was performed to identify optimal candidates.
Main Results:
- Adjusting additive proportions can effectively alleviate microplastic harm.
- DBDPO-2 and DBDPO-5 emerged as eco-friendly alternatives, enhancing microalgae carbon fixation and sedimentation by over 25%.
- DBDPO derivatives improved CO2 and ribulose-5-phosphate adsorption by amino acids, increasing microplastic surface area.
Conclusions:
- Modified DBDPO derivatives offer a promising solution for mitigating microplastic impacts in lakes.
- These derivatives enhance both microalgae carbon fixation and microplastic sedimentation.
- The study provides a scientific basis for protecting and sustainably developing lake ecosystems.
