Effects of exposure to ethylene glycol ethers on shipyard painters: I. Evaluation of exposure.

An industrial hygiene survey was performed to characterize exposure of shipyard painters to 2-ethoxyethanol (2-EE) and 2-methoxyethanol (2-ME). One hundred and two samples were taken over six workshifts. Overall results showed that the time-weighted average (TWA) of airborne exposure to 2-EE ranged from 0-80.5 mg/m3 with a mean of 9.9 mg/m3 and a median of 4.4 mg/m3. Samples for 2-ME TWA ranged from 0-17.7 mg/m3 with a mean of 2.6 mg/m3 and a median of 1.6 mg/m3. Limitations of the sampling and a few prior measurements suggest that these data may underestimate usual or previous exposure. These data are discussed in the context of available data on airborne exposure to ethylene glycol ethers from other workplaces.
