Objective To understand the status of occupational health hazards in Chinese herbal medicine establishments and to explore occupational health management strategies for such establishments. Methods The airborne microorganisms, SO2, CO2 concentration and inhalable dust (IP) in the Chinese herbal medicine establishments and control areas were determined, and the prevalence of respiratory diseases among employees was investigated. Results The total number of bacteria, respirable dust and CO2 in the air of the Chinese herbal medicine establishments were significantly higher than those in the control group. The total number of bacteria was positively correlated with the concentration of IP and CO2. The univariate analysis showed that the prevalence of respiratory system Significantly higher than the control group.
