No significant increase was detected in the number of chromosomally damaged cells in bone marrow of Chinese hamsters after either inhalation exposure to 300 ppm styrene or oral intake of 15% ethanol in drinking water (exposure time 4 days or 3 weeks). In combined exposure, a slight increase of chromosomal aberrations was observed in the group exposed for 4 days (2.0% aberrant cells vs. 0.0% in controls). The group exposed for 3 weeks to combined treatment showed no response (0.3% aberrant cells vs. 0.7% in controls).
中国仓鼠经吸入300 ppm苯乙烯或经口摄入饮用水中15%乙醇（暴露时间4天或3周）后，未检测到骨髓中染色体受损细胞数量有显著增加。在联合暴露中，暴露4天的组观察到染色体畸变略有增加（异常细胞为2.0%，而对照组为0.0%）。联合处理暴露3周的组无反应（异常细胞为0.3%，而对照组为0.7%）。
