Potential Health Risks Associated with Biodegradable Plastics and Future Research Prospects: A Focus on Biodegradable Microplastics
The global concern over white pollution and microplastic contamination caused by traditional non-degradable plastic waste has garnered widespread attention. Promoting biodegradable plastics (BPs) as alternatives to non-degradable plastics is a strategic approach to mitigating these forms of plastic pollution. However, under real-world environmental conditions, BPs often face challenges in achieving rapid degradation and may release significant quantities of biodegradable microplastics (BMPs) during the degradation process, posing potential environmental and health risks. In this review, we critically examine the environmental risks associated with traditional non-degradable plastic waste and the use of BPs. We systematically evaluate current pre-treatment techniques, analytical methods, and occurrence patterns of BMPs in environmental and biological samples. Furthermore, we highlight recent advancements in understanding the potential impacts of BMPs on organisms across various trophic levels, including human health. Finally, we address the challenges in applying BPs, particularly in identifying, analyzing, assessing health impacts, and developing future regulatory standards and measures for BMPs. This review provides theoretical foundations and technical guidance for advancing environmentally friendly and safe BPs.
1 Introduction
1.1 The importance of plastics in modern human social life and production
1.2 Ecological and environmental risks associated with the use of traditional refractory plastics
1.3 Production, application status, and potential risks of emerging degradable plastics
2 Analytical methods and environmental occurrence of degradable plastics
2.1 Methods for analyzing biodegradable microplastics
2.2 Environmental occurrence of degradable plastics
3 Research progress on potential environmental and health risks of biodegradable plastics
3.1 Potential ecological and environmental risks of degradable plastics
3.2 Potential health risks of biodegradable plastics
4 Conclusion and outlook
4.1 Insufficient public awareness of BPs and BMPs
4.2 Suitable for BMPs extraction and detection method vacancy
4.3 The long-term migration and transformation of BMPs in vivo and its health risks need to be clarified
4.4 Bioplastics and BMPs management and control methods and governance standards are missing
