A study on managing plastic waste to tackle the worldwide plastic contamination and environmental remediation
AI summary Read the abstract
This review examines the sources, distribution, and health effects of microplastic contamination worldwide, noting that global plastic production reached 359 million tonnes in 2020. Researchers found that microplastics account for roughly 75% of total marine waste and have been shown to cause toxic effects in humans and animals even at small concentrations. The study evaluates various waste management approaches aimed at reducing plastic contamination and supporting environmental remediation.
Over the past 50 years, the emergence of plastic waste as one of the most urgent environmental problems in the world has given rise to several proposals to address the rising levels of contaminants associated with plastic debris. Worldwide plastic production has increased significantly over the last 70 years, reaching a record high of 359 million tonnes in 2020. China is currently the world's largest plastic producer, with a share of 17.5%. Of the total marine waste, microplastics account for 75%, while land-based pollution accounts for responsible for 80-90%, and ocean-based pollution 10-20% only in overall pollution problems. Even at small dosages (10 μg/mL), microplastics have been found to cause toxic effects on human and animal health. This review examines the sources of microplastic contamination, the prevalent reaches of microplastics, their impacts, and the remediation methods for microplastic contamination. This review explains the relationship between the community composition and the presence of microplastic particulate matter in aquatic ecosystems. The interaction between microplastics and emerging pollutants, including heavy metals, has been linked to enhanced toxicity. The review article provided a comprehensive overview of microplastic, including its fate, environmental toxicity, and possible remediation strategies. The results of our study are of great value as they illustrate a current perspective and provide an in-depth analysis of the current status of microplastics in development, their test requirements, and remediation technologies suitable for various environments.

The world of plastic waste: A review
AI summary Read the abstract
This review provides a broad overview of the global plastic waste crisis, noting that over 359 million tons of plastic are produced annually and much of it ends up polluting the environment. Plastics break down into micro and nano sizes that spread through air, water, and soil, harming wildlife through ingestion and entanglement and threatening human health through cardiovascular disease, kidney problems, and cancer. The authors discuss end-of-life solutions including recycling, energy recovery, and biodegradable alternatives.
