摘要

Aim

Airborne chemical exposures pose persistent occupational health risks across industrial, agricultural, and laboratory environments. Recent advances in wearable sensing technologies provide new opportunities for cumulative personal exposure assessment. However, existing evidence is dispersed across multiple disciplines, creating the need for a consolidated synthesis. This scoping review maps the current landscape of wearable chemical dosimeters used for occupational exposure monitoring.

Subject and methods

Comprehensive searches were conducted in PubMed, Scopus, Web of Science, IEEE Xplore, and ScienceDirect, supplemented by Google Scholar and occupational safety agency resources. Studies published between 2015 and 2025 were screened against predefined inclusion criteria. Eligible studies were charted and synthesized narratively to describe wearable device types, chemical analytes monitored, validation approaches, and occupational deployment settings.

Results

The evidence base included diverse wearable dosimetry technologies such as active and passive volatile organic compounds (VOC) samplers, nanomaterial-enabled gas sensors, microfluidic detectors, fabric-integrated sensing platforms, aerosol monitors, and silicone-based passive samplers. Target analytes ranged from ammonia, nitrogen dioxide, VOCs, and formaldehyde to polycyclic aromatic hydrocarbons, pesticides, and industrial solvents. Devices were evaluated through laboratory validation, prototype testing, and field deployment across agricultural, industrial, construction, firefighting, and mining settings. Performance varied substantially, with advances in sensitivity, selectivity, and connectivity noted.

Conclusion

Wearable chemical dosimeters represent an emerging and rapidly evolving toolset for occupational exposure assessment. Current evidence demonstrates promising technological innovation and increasing feasibility for real-time or cumulative monitoring; however, device performance, standardization, and field robustness remain inconsistent.
