Abstract

Environmental contamination has become a significant issue worldwide, primarily driven by human activities. A multitude of scholarly articles are disseminated globally within the field of environmental chemistry, reflecting its vast potential to address this issue in a sustainable manner. This article conducts a bibliometric assessment of research outputs, concentrating on publications, citations, and citations per document from the leading 30 countries globally, spanning the years 1996 to 2023 to substantiate the documentation. The analysis of research expansion in relation to GDP, yearly growth, the number of universities, and indexed scientific journals within the designated field from 2007 to 2023 encompassed China, the United States, the United Kingdom, India, and Germany. Bibliometric information was obtained from the SCImago electronic database linked to Scopus. In the year 2022–23, China allocated 2.4% of its total GDP to research, while the United Kingdom invested 1.7%. The United States dedicated 3.4%, and Germany contributed 3.1%. In contrast, India spent only 0.65% of its GDP on research. In 2023, the citation per document for China, the United States, the United Kingdom, India, and Germany were 20.14, 31.98, 35.94, 18.32, and 28.85, respectively. Interpreted data likely explains the lower H index of India in comparison to China, the United States, Germany and the United Kingdom. Indian policymakers ought to emphasize research that focuses on practical solutions by promoting efficient collaboration with both domestic and global experts to tackle the recognized challenges.
