[Occupational health investigate of 1-bromopropane used in a factory]

Objective: To investigate the occupational health survey of 1-brominepropane (1-BP) enterprises and understand the impact of 1-BP on the health of occupational exposure population. Methods: The occupational health data of 15 1-BP workers were collected from 3 time nodes in 0 months, June and December, and the effects of occupational exposure to 1-BP on health were analyzed. Results: In the workplace with pure 1-BP, the mean air concentration in the workplace was 26.8 mg/m(3), and the personal contact level was 29.7 to 63.4 mg/m(3). The occupational health monitoring data showed that white blood cell count (WBC) , red blood cell count (RBC) , aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were compared in 0 months, June, and 12 months, the difference was statistically significant (P<0.05) . Conclusion: During the 12 months observation period, the occupational exposure to 1-BP caused the number of peripheral blood erythrocyte and leukocyte count and the level of alanine transaminase in the workers, but it did not exceed the normal reference range.
