Plastic pollution induced by the COVID-19: Environmental challenges and outlook
AI summary Read the abstract
Researchers used bibliometric analysis to map research on plastic pollution generated by the COVID-19 pandemic, finding that wealthier nations led early inquiry while developing countries followed, and revealing that pandemic-related plastics — from masks to medical waste — are creating cascading contamination from land to ocean to atmosphere.
The COVID-19 pandemic has also caused an environmental challenge, especially plastic pollution. This study is aimed to provide a systematic review of the current status and outlook of research on plastic pollution caused by the COVID-19 pandemic using a bibliometrics approach. The results indicate developed countries were the first to pay attention to the impact of plastics on the ocean and ecological environment during COVID-19 and conducted related research, and then developing countries followed up and started research. Research in developed countries is absolutely dominant in plastic pollution induced by the COVID-19, although the plastic pollution faced by developing countries is also very serious. The author's co-occurrence analysis shows the Matthew effect. Keyword clustering shows that plastics have a harsh chain-like impact on the ecological environment from land to ocean to atmosphere. The non-degradable components of plastic bring a serious impact the ocean ecosystems, and then pose a serious threat to the entire ecosystem environment.
