Abstract: Objective To understand the present condition of occupational health work in enterprises using benzene series and promote the prevention and control of occupational hazards in Baoshan District. Methods A total of 16 selected enterprises were investigated. The concentration of benzene series at workplaces were measured and exposure level of workers were surveyed with individual sampling. All data related to occupational health work in these enterprises were collected. Results Field investigation showed the dimethylbenzene concentrations at some workplaces (5.6% of samples) were not compliant with national standard. Personal sampling showed 1 worker had higher exposure level than the limits value. The direct cost for occupational health work in 16 enterprises was 2 098 million RMB and 3 240 RMB per worker. The occupational health examination showed there was no significant difference among different sub-group workers(P>0.05). Conclusion Supervision should be still strengthened on enterprises in occupational health work to ensure protecting workers'health.
