Firefighters exposed to burning polyvinyl chloride (PVC) were studied to assess respiratory effects at 5-6 wk post-incident and again 22 mo following the fire. Exposed subjects reported significantly more frequent and severe respiratory symptoms at both time points than did firefighter controls. In longitudinal analyses, a number of symptoms persisted over time, and acute symptom scores were significantly correlated with chronic scores. At Time 2, approximately 18% of exposed firefighters, compared with none of the controls, reported that since the time of the PVC exposure, a physician had told them that they had either asthma and/or bronchitis.
对接触燃烧聚氯乙烯（PVC）的消防员进行了研究，以评估事故发生后5至6周以及火灾发生22个月后的呼吸影响。在两个时间点，接触组受试者报告的呼吸道症状比消防员对照组更频繁、更严重。在纵向分析中，许多症状随时间持续存在，急性症状评分与慢性症状评分显著相关。在时间2时，约18%的接触PVC的消防员报告称，自接触PVC以来，医生告知他们患有哮喘和/或支气管炎，而对照组无人报告此类情况。
