Obstetric histories of women occupationally exposed to styrene.
研究对比67名职业接触苯乙烯的女性工人与67名无化学暴露的女工，发现接触组在暴露期间生育数显著降低，部分原因是人工流产增多，但自然流产数无差异。
To evaluate the possible embryotoxic effects of styrene, 67 female lamination workers occupationally exposed to styrene and 67 age-matched female industrial workers with no obvious chemical exposure were interviewed. The women, all under 40 a of age, did not differ significantly with respect to number of births, pregnancies, or spontaneous and induced abortions prior to the exposure period. During the styrene exposure the number of births was significantly lower among the exposed group, a result partly explained by a higher number of induced abortions. No differences were found in this material with regard to the number of spontaneous abortions.
