This paper explores the dose-response relation between formaldehyde (HCHO) concentration and reported health complaints (eye irritation, nose/throat irritation, headaches and skin rash) of nearly 2,000 residents living in 397 mobile and 494 conventional homes. The study analyzes the effects of HCHO concentration, age and sex of respondent, and smoking behavior on each of the four health effects. The results demonstrate a positive dose-response relation between HCHO concentration and reported health complaints, with reported health complaints demonstrated at HCHO concentrations of 0.1 ppm and above. Concentrations of 0.4 ppm in manufactured homes as targeted by the Department of Housing and Urban Development (HUD), may not be adequate to protect occupants from discomfort and from acute effects of HCHO exposure.
本文探讨了甲醛(HCHO)浓度与居住在397个移动房屋和494个传统房屋中的近2000名居民报告的健康问题(眼睛刺激、鼻子/喉咙刺激、头痛和皮疹)之间的剂量反应关系。该研究分析了HCHO浓度、受访者的年龄和性别以及吸烟行为对这四种健康影响的作用。结果表明,HCHO浓度与报告的健康问题之间存在正剂量反应关系,在HCHO浓度达到0.1 ppm及以上时就有报告的健康问题。住房和城市发展部(HUD)设定的预制房屋中0.4 ppm的浓度,可能不足以保护居住者免受不适以及HCHO暴露的急性影响。
