Cutting‐Edge Strategies and Advancements for Combating Synthetic Polymer Pollution in Various Environmental Samples: A Review
AI summary Read the abstract
This review surveys cutting-edge strategies for detecting and combating synthetic polymer pollution, including nanoplastics and microplastics, across environmental samples. Researchers summarized advanced analytical techniques for identification and quantification, along with emerging remediation approaches. The study highlights that despite growing awareness, significant challenges remain in developing standardized methods for monitoring and cleaning up plastic pollution across air, water, and soil.
Abstract Plastic debris is unavoidably released into the ecosystems, and their physicochemical and mechanical qualities deteriorate when exposed to the environment. This, ultimately, leads to the generation of tiny fragments of plastic, which are known as nanoplastics (<1000 nm) and microplastics (<5 mm). Over the past few years, the pollution of synthetic polymers has been reported in almost all the compartments of the environment across the globe. It is regarded as a hazard to both human health and natural systems. In addition, synthetic polymers act as vectors for contaminants as they can adsorb and accumulate contaminants from seawater. The accumulation of plastic waste in the environment and its widespread presence have drawn the attention of policymakers and the public. This global issue has led to the creation of numerous remediation solutions by innovators in previous decades, either to clear up old waste or to stop plastic from entering the various matrices of the environment. This review focused on the extensive scientific research available on effective techniques for removing plastic debris to promote positive action and progress in this important area. Despite the various challenges, these techniques offer vital opportunities, from increasing awareness to enhancing environmental quality. Further, the article has been enriched by incorporating bibliometric data that illustrates the widely used methods for removing microplastics from various environmental matrices. According to the data analysis, numerous remediation techniques have been developed to date (2010 and 2024). These techniques encompass various approaches, among which the chemical‐based methods enjoy more success. This success can be attributed to the diverse advantages offered by chemical‐based methods over other remediation techniques. Much research is now focused on overcoming the disadvantages and developing more efficient and environmentally sound technologies.
