The perception of odour may result in some individuals reporting subjective sensory irritation, and individuals may perceive formaldehyde at concentrations below mg/m3 . However, this is not considered to be an adverse health effect. The NOAEL of mg/m3 for the eye blink response is adjusted using an assess- ment factor of 5 derived from the standard deviation of nasal pungency (sensory irritation) thresholds, leading to a value of mg/m3 , which has been rounded down to mg/m3 . Neither increased sensitivity nor sensitization is considered plausible at such indoor concentrations in adults and children. This value is thus considered valid. | EAST-WEST CENTER WORKING PAPERS EAST-WEST CENTER The East-West Center is an education and research organization established by the .
