The originality of this work consisted in assessing both acute exposure during or after using household products, and chronic exposure through exposure situations in various, regularly frequented places. The quantitative risk assessment was conducted on the basis of toxicity reference values (TRVs) for acute and chronic exposure and a range of hazard quotients (HQ) was calculated in both contexts. For almost all of the consumer products, tested in normal conditions of use, acute inhaled formaldehyde concentrations are lower than the TRVs calculated to protect against ocular and nasal irritation. However, for three domestic products, acute TRVs are reached or exceeded, and exposures are thus capable of causing ocular and nasal irritation. Regarding chronic exposure, the time spent in the home leads to inhaled concentrations exceeding the chronic TRVs protecting against long-term ocular and nasal irritation. The dose-effect relationship does not indicate the occurrence of other non-carcinogenic effects, even for the highest inhaled concentrations and for the worst case scenario. It appears that the highest inhaled concentrations are at only one tenth of the levels for which irritations might trigger nasopharyngeal cancer.
