Bibliometric analysis of ammonia risk assessment: research trends, challenges, and future directions
摘要
This study provides a bibliometric overview of global research trends in ammonia risk assessment from 2000 to 2025, with a focus on workplace safety, environmental impacts, and industrial applications. It used the Scopus and Web of Science databases to find, filter, and evaluate a total of 1,568 relevant papers. The crowd utilized science mapping tools, such as VOSviewer, to conduct the analysis. The study reveals that the number of publications has increased, particularly after 2015. This is because people are becoming increasingly concerned about the dangers of ammonia in areas such as refrigeration, farming, and chemical manufacturing. Maps of co-authorship and institutional collaboration show that China, the United States, and several European countries have made significant contributions to research. Three thematic research clusters were identified; chemical hazards of ammonia and their impact on human health, assessing and controlling ammonia risks, and industrial safety and operational reliability. People are increasingly using new methodologies, such as Bayesian networks (BN) and Areal Locations of Hazardous Atmospheres (ALOHA) simulations. Nonetheless, deficiencies persist, especially with the incorporation of human elements in risk mitigation and the effects of prolonged exposure. In conclusion, this sway andiews important scientific progress, organizes the area in a systematic way, and gives strategic advice for future research on how to safely handle ammonia.
