Abstract:
Objective To investigate the occupational health conditions in a 1-bromopropane manufacturing plant and to understand the relationship between occupational exposure and health.
Methods Information on the technical process of 1-bropromane production and the occupational history, basic information, and health examination data of 21 workers were collected. Fixed site and personal sampling methods were used to determine concentrations of 1-bromopropane at the selected working spaces and individuals respectively. Relationship between 1-bromopropane exposure and health condition of the workers was analyzed.
Results 1-bromopropane was detected at all of the selected worksites with a maximum of 153.08 mg/m3 at the site close to the receiving pot, the highest geometric mean concentration (43.62 mg/m3) was found in the distilling room, and the lowest (1.95 mg/m3) was located outside the production line. There were no significant differences between the active and the passive samples in the individual exposure levels (P>0.10). The health examination data showed no obvious health effects caused by 1-bromopropane exposure.
Conclusion The workers' health is not affected by 1-bromopropane manufacturing under the current exposure level.
