Assessment of Exposures and Health Risks Related to Formaldehyde Emissions from Furniture: a Case Study

摘要: According to the Californian Safe Drinking Water and Toxic Enforcement Act, Proposition 65 (State of California, 1986) manufacturers retailers products (such as furniture fittings) which emit formaldehyde are obliged either mark their with a warning label or provide evidence that do not pose significant cancer risk consumer. The is defined 1 case in population 100,000 persons within period exposure 70 years 1992). In this study, large-scale climate chamber test full set fitments was made. concentration peaked at about 112 μg/m3 day after had been installed. After 8 weeks leveled out 50 μg/m3. Various models were used predict occupant exposures homes containing same fitments; multi-compartment identified short-term compartment half-life between 5.2 6.0 h relative source strength 75% 30% total strength; medium-term 14 81 days; long-term for best estimate 384 days. The accumulated dose absorbed by an during hypothetical home estimated extrapolation using models. found be range 0.13 g 0.16 g. The showing maximum value may cause discomfort among hypersensitive first couple days. estimates based on indicate risks associated caused 6.9 8.9 × 10−8, monkey data, 5.8 7.4 10−7, rat data. In conclusion, successful draft protocol established tests relation and, limitations exploratory actual equipment considered no consumer according Proposition.
