↵3-151 At the time of anamnesis (1992–3) after shut down of original production activities in 1989: the currently exposed group had 3 years of low exposure to styrene, and the formerly exposed group had ended exposure 3 years previously. Until 1989, both groups had the same moderate to high exposure to styrene.
