Bibliometric Analysis on Contaminant Microplastics in Compost (2018 to 2022) Through VOSviewert

Compost is considered not only to improve soil nutrients but also as a carrier of microplastic (MPs) pollution on agricultural land. Bibliometric analysis is a quantitative review approach that employs statistics, data mining, and mathematics to identify new academic trends. It is increasingly more prevalent and is utilized in several academic disciplines. To evaluate the evolution and extension of this body of knowledge and to forecast its future path, the present study analyzed Scopus-indexed research publications on compost from 2018 to 2022. To perform the bibliometric analysis, the VOSviewer software and Scopus Analytics were used. A total of 111 journal articles (n = 77) and conference papers (n = 3) were extracted. The number of research documents published by 111 authors was steadily increasing annually. China is the leading country in the number of publications and research collaborations. The current results offset global scientific efforts on MPs contamination in compost and inform that there is potential for compost to be a carrier of MPs contaminants in plants.
