Objectives: The purpose of this study was to evaluate the personal exposure to PM₁₀ by body parts for the development of dust monitoring wearable device for swine farmers. Methods: Tasks were classified by using motion pictures taken by action cameras attached to swine farmers. Concentrations of PM₁₀ were measured by attaching direct-reading instruments at the head, neck and waist of worker. Differences of PM₁₀ exposure between body parts were analyzed with linear regression. Results: We identified three tasks(vaccination, moving pigs, and manure treatment). PM₁₀ concentration during vaccination was the highest among the tasks, and the body part showing the highest concentration of PM₁₀ was the waist regardless of task. In all tasks, the closer distance between the body parts, the higher were the R-squared values(vaccination 0.4221, moving pigs 0.6990, and manure treatment 0.2164). Conclusions: We presumed that PM₁₀ concentrations were affected by the parts of the body in which they were measured. In order to develop swine farmer’s wearable device for monitoring dust concentration in air, the determination of the positions of monitoring sensor to ensure accurate measurement is essential. Considering the results of this study, wearable sensor should be positioned at the waist.
