From a cohort of 1,768 Boston fire fighters studied initially in 1970, pulmonary function measurements were repeated on 1, 146 active subjects in 1974. The mean time between examinations was 3.4 years. The data on 1,430 subjects after one year of follow-up had indicated excessive decrements in levels of forced vital capacity and one-second forced expiratory bolume which were related to the frequency of fire exposure. The annual decline over three years was less than that observed over one year and could not be related to the number of fires fought or to other indices of acute fire exposure. Selection factors within the fire department appear to be important in protecting fire fighter from continued loss ventilatory capacity.
在1970年最初研究的1768名波士顿消防员队列中，1974年对1146名在职受试者重复进行了肺功能测量。两次检查之间的平均时间为3.4年。对1430名受试者进行一年随访后的数据表明，用力肺活量和一秒用力呼气量水平过度下降，这与接触火灾的频率有关。三年期间的年度下降幅度小于一年内观察到的下降幅度，且与扑救火灾的次数或其他急性火灾暴露指标无关。消防部门内部的选择因素似乎对保护消防员避免持续的通气能力丧失很重要。
