HEALTH AENV SIRS 79 – 89
Section 14.1
ASHRAE 1981; AWMA 2000; Fazzalari 1991; NIH 2004, website; Ruth 1986;
US EPA 1992; van Gemert and Nettenbreijer 1977). For most COPCs, the mean
odour thresholds and range of values reported in the literature are listed. The
lower the odour threshold, the more odorous the chemical. The lower end of the
range represents the “minimum” odour threshold.
Metals were not included in the odour assessment as information regarding odour
character and odour thresholds was not available.
