Previous research in environmental and occupational health has suggested that fluctuations in the sex ratios of births might provide a useful early warning to the possible health effects of toxins or other stresses in the environment. To examine further this hypothesis, we investigated the sex ratios of births in an area in central Scotland which contained two incineration plants. Analyses of the sex ratios, at various levels of geographical detail and using 3-dimensional mapping techniques, in the residential areas at risk from airborne pollution from these incinerators showed locations with statistically significant excesses of female births.
此前在环境与职业健康领域的研究表明，出生性别比的波动可能为环境中毒素或其他压力源对健康可能产生的影响提供有用的早期预警。为了进一步检验这一假设，我们调查了苏格兰中部一个有两座焚烧厂的地区的出生性别比。利用三维绘图技术，在不同地理细节层面上，对这些焚烧厂空气污染影响范围内的居民区的出生性别比进行分析，结果显示某些地点女婴出生数在统计上显著偏高。
