This review examines microplastic pollution using a DPSIR framework, detailing sources, environmental states, impacts, and current/developing responses. It identifies research gaps and future directions for addressing microplastic contamination.
Area of Science:
- Environmental Science
- Ecotoxicology
- Pollution Control
Background:
- Microplastic pollution is a pervasive global environmental issue.
- Understanding the complex dynamics of microplastics is crucial for effective management.
Purpose of the Study:
- To synthesize current knowledge on microplastic pollution using the DPSIR framework.
- To review existing and emerging solutions for mitigating microplastic pollution.
- To identify research trends and gaps in the field of microplastic pollution.
Main Methods:
- Systematic literature review and analysis.
- Application of the Driving Forces, Pressures, States, Impacts, and Responses (DPSIR) framework.
- Identification and categorization of research trends and knowledge gaps.
Main Results:
- Comprehensive overview of microplastic sources, environmental distribution, and impacts.
- Detailed analysis of upstream and downstream response strategies, including policy, technology, and education.
- Identification of key research gaps and future research priorities.
Conclusions:
- Effective microplastic pollution management requires a multi-faceted approach integrating various response strategies.
- Further research is needed to fill identified knowledge gaps, particularly in understanding long-term impacts and developing novel solutions.
- The DPSIR framework provides a valuable structure for organizing and advancing research on microplastic pollution.
