To analyze the effects on color vision of chronic exposure to mixtures of solvents including ethyl acetate, ethanol, and ketones among the workers of a large factory specializing in the manufacture of photoengraved aluminum packaging.
We analyzed a group of 129 subjects who had been exposed to solvents for more than 3 years (mean age 40 years, range 25-59 years) and a nonexposed group of 120 subjects (mean age 41 years, range 21-57 years).
The two groups had a similar length of service (17 and 19 years on average, respectively).
The exposed subjects consumed more tobacco and alcohol than the nonexposed workers.
The study involved administration of the Lanthony D-15 desaturated test.
The subjects were classified as having or not having dyschromatopsia on the basis of Lanthony's criteria and the chromatic confusion index (CCI) was calculated according to Bowman's method.
After observation of the work stations and analysis of an occupational questionnaire the findings were used to construct a cumulative exposure index covering the whole of each subject's working life.
Air samples were taken at each work station and in each production sector to determine current exposure.
The average cumulative exposure index was 194 (median 174, range 27-513). (...)
