Small Plants and Their Medical Problems - The Furniture Industry. The Environmental Problems of Urea-Formaldehyde Structures - Formaldehyde Exposure in Mobile Homes.
NIOSH 1980 Jun:56-64
The effect of formaldehyde (50000) (HCHO) on health of inhabitants of mobile homes was studied. The initial analysis of mobile homes showed the presence of HCHO in concentrations of 0.64 to 1.3 parts per million (ppm). A survey of 334 mobile homes, in which one or more persons experienced health problems revealed HCHO concentrations 0.03 to 1.77ppm. Of 608 samples collected, 66 percent were between 0.1 and 0.49ppm, 21 percent were 0.5ppm or greater. The affected individuals were 240 adult females, 184 adult males, and 99 children. The most prevailing symptoms were eye and throat irritation. Thirty three percent of children experienced cough or cold symptoms. Chronic headache, memory lapse, and drowsiness was reported by a large number of persons. Chronic nausea was less frequently encountered. A smaller number of elderly experienced chest pains and heart attacks after moving into mobile homes. Long time sufferers developed acute mental depression. The only way to minimize indoor atmospheric HCHO concentration was flow through ventilation without recirculation. The author concludes that industrial workplace standards can not be used for the home environment. Complexity of the home environment makes attempts to set up exposure standards extremely complicated.
