Abstract
Objective: To determine whether methyl bromide (MB) fumigation work for plants imported in Korea affects workers health by assessing heart rate variability (HRV). Methods: We measured HRV indices (TP, VLF, LF, HF, HR, SDNN, pNN50 and HRV-index) and urinary bromide ion (Br) in 62 fumigators (study group) and 34 inspectors (the control group) before and after fumigation work. In addition, the relationship between Br concentration and HRV indices was analysed. Results: The fumigators post-work HRV indices and Br level were changed compared with their pre-work values (P 0.001). Conversely, inspectors values were not shown a difference before and after work. The HRV indices in all subjects were negatively correlated with the Br levels (P 0.05). Conclusions: Fumigators with high Br concentrations and low post-work HRVindices followingMBfumigation work experienced adverse effects on their autonomic nervous systems.
