A Bibliographic Analysis of Indoor Air Quality (IAQ) in Industrial Environments

Abstract

Air pollution is a major risk factor, and it still remains a global cause of death for millions of people. Indoor air quality (IAQ) plays an important role in human health as people spend most of their time in confined spaces. Many studies have recently addressed this issue, but no systematic analysis has been conducted, which is the aim of our study. We present a bibliographic analysis of articles on IAQ in industrial environments from 2010 to 2021. A total of 658 articles were collected, and 409 were used. The NVivo tool was used to analyze the collected documents both quantitatively and qualitatively. This analysis of the literature enables us to identify the most studied working environments and pollutants, the analysis tools, and the types of measurement used to provide a clear overview of the theme, which includes a comparison between the studied working environments and the state of origin of the authors. Our analysis of each working environment and the related frequently cited pollutants provides a clear approach to identifying the specific areas of focus when improving the quality of the air in a specific working environment. In addition, a research gap and future research areas have been identified in the conclusions.
