Bibliometric Mapping of Indoor VOCs Exposure in Pregnant Women and Infants- Research Trends, Health Risks, and Mitigation Strategies in the Context of Sustainable Development Goals (SDGs) 3

Abstract

While previous research has shown that early life exposure to Volatile Organic Compounds (VOCs) can have serious developmental and neurotoxic effects, existing macro-reviews have failed to capture thematic priorities and more specific collaboration patterns within the Environmental Science literature in developing countries. This study attempts to fill this gap by mapping the intellectual structure, thematic dynamics, and health risks of indoor VOC exposure among vulnerable populations (pregnant women and children) in the ASEAN region over the period 2003–2025. Through a bibliometric analysis of a curated corpus of articles, the study maps authorship networks, co-occurrence of terms, and changes in research focus over time. The results indicate that regional collaboration remains fragmented and heavily dependent on international partners. The literature also focuses primarily on PM2.5 and PAHs, but important clusters related to SVOCs such as phthalates and flame retardants are emerging, which are linked to indoor dust and infant exposure. These findings emphasize the importance of controlling Semi-Volatile Organic Compound (SVOC) sources and household mitigation strategies to support the achievement of health targets in the ASEAN region.
