The contamination of the Michigan food supply by polybrominated biphenyls (PBBs) in the mid-1970s appears to have had little or no impact on fetal mortality. Comparison of fetal death rates among residents of Lower Peninsula counties with a high percentage of quarantined farms and among residents of Upper Peninsula counties with no quarantined farms reveals no important differences in rates or trends after the contamination. Since counts of early spontaneous abortions are lacking, a complete assessment of the possible impact on reproductive outcome cannot be made.
20世纪70年代中期,密歇根州的食品供应受到多溴联苯(PBBs)污染,这似乎对胎儿死亡率几乎没有影响。对下半岛县有高比例隔离农场的居民和上半岛县没有隔离农场的居民的胎儿死亡率进行比较,结果显示污染后在比率或趋势上没有显著差异。由于缺乏早期自然流产的统计数据,因此无法对其对生殖结果的可能影响进行全面评估。
