Examining Current Research Trends in Ozone Formation Sensitivity: A Bibliometric Analysis
Summary
This study presents a bibliometric analysis of ozone formation sensitivity research published from 1965 to 2022, finding a constant expansion of publications since 2008 with the USA contributing 42.7% of papers, followed by China (13.5%) and the UK (9.1%). Citation burst and keyword analysis revealed that 'volatile organic compounds' and 'ozone precursors' have emerged as increasingly frequent research themes in recent years.
The end of the 20th century brought about drastic changes in the tropospheric ozone (O3) around the globe. It is, therefore, highly important to gain insight into O3 formation mechanisms and their key precursors in order to assist policymaking to combat O3 pollution. This article synthesizes a bibliometric analysis of O3 formation sensitivity from 1965 to 2022, reported in English language journals available in the Web of Science Core Collection. This study shows that constant expansion in the number of publications has occurred since 2008, with the highest number occurring in 2021. Most publications are from the United States of America (USA), with 406 papers (42.7%), followed by China with 128 papers (13.5%), and the United Kingdom (UK) with 87 papers (9.1%). Citation burst analysis and significant and highly cited research work analysis are used to discover and assess evolving research tendencies. The thematic evolution of author-supplied keywords indicates that the terms “volatile organic compounds” and “ozone precursors” have recently emerged with a higher frequency. This suggests that there is a growing trend in research focused on these topics in the future. The objective of this study is to provide research primacies and future prospects for better analysis of O3 sensitivity, thereby helping to manage O3 pollution.

Scientometric Analysis of Microplastics across the Globe
A scientometric analysis of 8257 microplastics publications from 1980-2021 found that the term microplastics as a pollution descriptor emerged in 2004 and publication rates grew dramatically from 2014 onward, with China, USA, Germany, and the UK as leading research nations.
Climate change: Does international research fulfill global demands and necessities?
Researchers conducted a bibliometric analysis of global climate change research output, finding that the countries publishing the most scientific papers — led by the US, UK, and China — are often not the most vulnerable to climate impacts, while developing nations facing the greatest risks produce little research. The study reveals a significant gap between where climate science is produced and where it is most urgently needed.
