Formaldehyde-related health complaints of residents living in mobile and conventional homes

Abstract

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.
