On the degradation of (micro)plastics: Degradation methods, influencing factors, environmental impacts

Lingchen Liu et al.

Summary: Plastics and microplastics are difficult to degrade in the natural environment due to their unique properties, such as hydrophobicity and stable chemical bonds; microplastics can attract other substances, delaying degradation and potentially spreading harmful substances through the food chain. Degradation is an effective way to address plastic pollution, but still faces challenges and requires further research and development of new degradation methods.

Summary: Microplastic pollution was systematically investigated in the Yangtze River Basin of China, including water, sediments, and soils. The abundance of microplastics showed a generally increasing trend from upstream to downstream, influenced by geographical and anthropogenic factors. Microplastics in sediments exhibited more prominent vertical migration than those in soils, with density and size playing key roles. The abundance and distribution of microplastics were significantly different among different compartments and correlated with geographical distance.

Risk assessment of microplastic particles

Albert A. Koelmans et al.

Summary: This Review examines the properties of microplastic particles and discusses methods of assessing the risks they pose to humans and the environment. Microplastic particles are widespread in the environment and can be found in the air we breathe and the food we eat. The lack of a risk assessment framework that considers the multidimensionality of microplastic particles compared to natural particles is a key challenge. This article reviews current understanding of microplastic characteristics and effects and proposes a method for quantifying exposure and effect thresholds using probability density functions.

Recent developments in microbial degradation of polypropylene: Integrated approaches towards a sustainable environment

Ashvinder Kumar Rana et al.

Summary: Fossil-fuel-based plastics have caused significant environmental issues, but some bacteria have the ability to degrade and metabolize them, suggesting the potential of biotechnologies based on plastic biodegradation. Polypropylene (PP), one of the most consumed plastics, is somewhat difficult to degrade under natural conditions, but scientists have made efforts in using other microbes and materials to enhance its biodegradation. Current methods such as gravimetric analysis and physical characterization are not sufficient to confirm the biodegradation of PP, so new techniques need to be explored. Further studies are also needed to investigate plastic-degrading microorganisms and improve enzymatic strategies.
