Spontaneous abortions were analyzed in an industrial community in Finland in relation to the occupation of women and their husbands, and to the level of air pollution in the family's residential area. Information on abortions and births was obtained from the hospital discharge register; information on the women and their families was obtained from the files of the population and housing census. Women who were employed in rayon textile jobs and paper products jobs had an increased rate (P less than 0.10) of spontaneous abortions; the wives of men employed in transport and communication, in rayon textile jobs, and in chemical process jobs also had an increased rate of spontaneous abortions. In material stratified for age, parity, and socioeconomic class no evidence was found that the level of sulfur dioxide or carbon disulfide could be associated with a risk of spontaneous abortions. More spontaneous abortions were noted in all socioeconomic classes in areas where the mean annual level of hydrogen sulfide exceeded 4 micrograms m-3. However, the difference (total rates 7.6 and 9.3, respectively) was not significant statistically.
在芬兰的一个工业社区，对自然流产情况进行了分析，涉及女性及其丈夫的职业，以及家庭居住地区的空气污染水平。流产和生育信息来自医院出院登记册；女性及其家庭的信息来自人口与住房普查档案。从事人造丝纺织工作和纸制品工作的女性自然流产率有所上升（P<0.10）；从事运输与通讯、人造丝纺织工作以及化工工艺工作的男性的妻子自然流产率也有所上升。在按年龄、产次和社会经济阶层分层的资料中，未发现二氧化硫或二硫化碳水平与自然流产风险有关联。在硫化氢年均水平超过4微克/立方米的地区，所有社会经济阶层的自然流产情况均更为常见。然而，两者差异（总流产率分别为7.6和9.3）在统计学上并不显著。
