Inhalation is an important pathway for human exposure to contaminants that exist as atmospheric gases and inhalation exposure frequently occurs as a result of direct release of such gases from an on-site facility. Formaldehyde is a chemical used widely by industry to manufacture building materials and numerous household products. It is also a by-product of combustion and certain other natural processes. This study addresses the assessment of formaldehyde exposure in a population group living in the surroundings of a wooden products factory using formaldehyde in the technological process. Simultaneous formaldehyde concentrations measurements controlled for weather conditions were performed at the plant level, outdoor and indoor for ten households in the surroundings of the plant. A health questionnaire was filled in by the study participants. Spirometry was also performed to investigate the pulmonary function of the subjects participating in the study.Exposure doses were calculated using the ATSDR (Agency for Toxic Substances and Disease Registry from CDC - Center for Disease Control and Prevention) Dose Calculator.In the worst case scenario, the additional estimated cancer risk, as a result of formaldehide exposure of the investigated population group in the surroundings of the plant, were between 10-6 and 10-3 as orders of magnitude.

Key words: formaldehyde, exposure dose, wooden products factory, respiratory health status.
