Objective: Methyl bromide (MB) fumigant has been shown to be fatal to human when was exposed. However, it were still used the significant amount in quarantine disinfection sites. The purposes of this study were to assess the MB exposure status and characteristics by fumigation-related workers and to provide supporting data for management plan.
Methods: For this study, the three groups related to fumigation work were composed. A total of 107 workers were directly exposed, 20 field inspectors were indirect, and 20 general quarantines were not exposed. The urinary bromide ion concentrations in each group were analyzed by using HPLC/ICP-MS, and the working characteristics were identified using the structured questionnaire.
Results: The urinary bromide ion concentration in the exposed group of fumigation workers was higher than the indirect and non-exposed groups. In the work characteristics of workers, there was a significant tendency to increase urinary bromide ion concentrations with higher fumigation work years (≤4 years: 2.84 (1.13-7.11) mg/g cr, >4-15 years: 5.36 (4.37- 6.57) mg/g cr, >15-37 years: 6.69 (5.27-8.49) mg/g cr, p=0.034). In the comparison of the average number of working days per month, the more working days, the higher the urinary bromide ion concentration was statistically significant (≤12.5 days: 2.59 (1.19-5.65) mg/g cr, >12.5-19.25 days: 5.46 (4.62-6.44) mg/g cr, >19.25-27.25 days: 7.93 (5.93-10.59) mg/g cr, p=0.002).
Conclusion: This study was the first nationwide survey including biological monitoring in workers exposed to methyl bromide. The results of this study were expected to be used as a reference for workers' health rights in relation to fumigation, prevention of addiction accidents, and safe management plan.
