Welding and flame cutting of epoxy coated steel at the shipyard give rise to fumes and gases. These fumes contain degraded products of epoxy resin paint such as bisphenol A. In this study, the bisphenol A concentration in worker's urines and fumes in the breathing zone during welding and flame cutting of coated steel was evaluated at the shipyard. High performance liquid chromatography(HPLC) with ultra-violet detector(UVD) was used for the assay of bisphenol A in urine and fume. Conugated Bisphenol A in acidic urine was hydrolyzed by the microwave-digest. The fume sampling was done using a glass fiber filter for bisphenol A during welding and flame cutting. Acetone was suitable for the extraction of Bisphenol A on the glass fiber filter(105%). The limit of detection of Bisphenol A was 1.0ug/ml by the HPLC/UVD. The averages and standard deviations of Bisphenol A concentrations in welding fumes, worker's urine and control group's urine were 64.46 ± 60.24ug/m3(n=16), 95.83±166.59ug/g creatinine(n=98) and 23.93±4.08ug/g creatinine(n=18), respectively. The bisphenol A concentration of the worker's urine was 4 times higher than the control group. The concentration of the bisphenol A in worker's urine on Monday was 3.3 times lower than Friday's concentration
