Objectives: Taxi drivers are exposed to various hazards, such as long periods of sedentary work and traffic-related air pollutants. However, studies on the health effects among taxi drivers in South Korea are insufficient. Methods: To assess subclinical hematologic change related to cardiovascular disease among male taxi drivers, we analyzed data from the second Korean National Environmental Health Survey. Fifty-nine taxi drivers and 1,912 controls were included in the analysis. Propensity score matching was performed to adjust for age, body mass index, and urinary cotinine. A total of 295 subjects were matched with 59 taxi drivers. Leukocyte count, platelet count, hematocrit, triglyceride, total cholesterol, HDL cholesterol land total IgE of the taxi drivers were compared with the control groups. Results: Taxi drivers showed significantly elevated blood leukocytes and platelets. Serum total IgE was significantly reduced in taxi drivers. However, blood leukocytes, platelets, and serum total IgE were not significantly correlated with work period among taxi drivers. Conclusions: Regarding the change of the blood leukocyte count, platelet count, and serum total IgE, taxi driving has the possibility to be associated with peripheral inflammation, humoral immunity and cardiovascular risk.

Objectives; To evaluate exposure of chemicals, especially organic solvent, of aircraft maintenance facility in Korean army. Methods; We sampled bulk sample of solvent and air sample from maintenece facility workplace; cleaning and painting process. Air sampling was done by area sampling and personal sampling method. Analysis of sampling was done by gas chromatography/ mass spectrometry. Results; Benzene, heptane, toluene, ethylbenzene, xylene were detected among cleaning process. Comparison of TLV limit value, benzene was detected at a level of 22% of time weighted average level. Toluene, ethylbenzene, xylene were detected among painting process. Conclusions; We detected several organic solvents which is not enlisted on material safety data sheet. Carcinogenic or reproductive toxic agents were detected. Although the level was lower than exposure limit, safetly and health issues of workers should be concerned.
