Based on the evaluation of more than 5000 X-rays pictures of the left hand and wrist of children living in areas with a different degree of atmospheric contamination in the CSSR, GDR and GFR evidence was provided that children living in areas with a high concentration of industrial exhalations are, as compared with reletively clean areas, significantly retarded in their skeletal maturation. This retardation was in the great majority greater in boys than girls which indicates a different reactivity of the two sexes to noxious agents of the external environment.
根据对捷克斯洛伐克社会主义共和国、德意志民主共和国和德意志联邦共和国不同程度大气污染地区5000多张儿童左手和手腕X光片的评估，有证据表明，与相对清洁的地区相比，生活在工业废气浓度高的地区的儿童骨骼成熟明显迟缓。这种迟缓在大多数情况下男孩比女孩更严重，这表明两性对外界环境有害因素的反应不同。
