In a pilot study, 11 workers were exposed to mixtures of organic solvents during the cleaning of printing rolls. The exposure was considered as low to moderate. The "electroencephalogram (EEG)" was recorded before and after the cleaning. The spectral power was calculated by Fast Fourier Transformation in six frequency bands. After exposure the spectral power in particular increased in the alpha-1 band and in the temporooccipital leads of the delta band in the closed-eye condition.
