The aim of this study was to investigate the effects of occupational exposure to 1,6-hexamethylene diisocyanate (HDI) on peak flowmetry in automobile body paint shop workers in Iran. We studied a population of 43 car painters exposed to HDI at their workplaces. Peak expiratory flow was tested for one working week, from the start to the end of each shift. Air was sampled and HDI analysed in parallel, according to the OSHA 42 method. Daily and weekly HDI exposure averages were (0.42+/-0.1) mg m(-3) and (0.13+/-0.05) mg m(-3), respectively. On painting days, 72 % of workers showed more than a 10 % variation in peak expiratory flow. Inhalation exposure exceeded the threshold limit value (TLV) ten times over. This strongly suggests that HDI affected the peak flowmetry in the studied workers.
本研究旨在调查伊朗汽车车身喷漆车间工人职业接触1,6 - 己二异氰酸酯（HDI）对呼气峰值流速测定的影响。我们研究了43名在工作场所接触HDI的汽车喷漆工人群体。在每个班次从开始到结束的一个工作周内对呼气峰值流速进行测试。按照美国职业安全与健康管理局（OSHA）42号方法，并行采集空气样本并分析HDI。每日和每周的HDI暴露平均值分别为(0.42±0.1)毫克/立方米和(0.13±0.05)毫克/立方米。在喷漆日，72%的工人呼气峰值流速变化超过10%。吸入暴露超过阈限值（TLV）达十次以上。这有力地表明HDI影响了所研究工人的呼气峰值流速测定。
