• , Ho Chi Minh City 700000, Vietnam 10.3762/bjnano.16.102 Abstract This study employs a bibliometric analysis using CiteSpace to explore research trends on the impact of biochar on microplastics (MPs) in soil and water environments. In agricultural soils, MPs reduce crop yield, alter soil properties

Keywords: aquatic pollution; bibliometric analysis; biochar; microplastics (MPs); soil remediation; Introduction Plastics are widely utilized in various industries and daily life due to their low production cost. The average global per

Moreover, bibliometric approaches have not been widely applied to visualize research trends in BC applications for MP mitigation. To advance the understanding of MP pollution and biochar’s remediation mechanisms, bibliometric analysis
