Chromosome investigations on workers exposed to styrene/polystyrene

Chromosomes investigations were undertaken on 12 employees with three to 34 years possible exposure to styrene in order to determine if there was a possibility of chromosome impairment. The data did not reveal any significant differences between persons exposed to styrene and members of the control group. The concentrations of styrene at the workplace were far below the MAC value and also the mandelic acid content of the urine was far below the norm.
