Occupational and Environmental BTEX Exposure: A Bibliometric Analysis Using Scientific Mapping

BTEX compounds (benzene, toluene, ethylbenzene, and xylene isomers) are aromatic hydrocarbons widely used in various industries. Due to their volatility, they become persistent pollutants in workplace air, posing serious risks to worker health. The aim of this study is to systematically map academic publications on BTEX exposure and health effects and to evaluate the impact of exposure levels in industrial settings on worker health. Publications obtained from the Web of Science database between 2010 and 2025 were bibliometrically analyzed in terms of productivity, collaboration networks, thematic trends, and analysis methods. In addition, the sources of BTEX compound dispersion, analysis methods, and industrial hazard classifications were evaluated through content analysis. According to the findings, Iran and China stood out as the most active countries, with publication intensity peaking in 2023. BTEX exposure was observed to be particularly high in the petrochemical sector. However, there is a lack of studies that systematically address the direct effects on worker health. This study aims to contribute to the more effective management of BTEX-related exposure risks by providing decision-makers with scientifically based and interpretable analyses.
