The panellists had their average individual n-butanol thresholds in the acceptable range of 20
to 80 ppb/v. One of the panellists conducted the on-site assessment each day alternatively at
a time randomly scheduled between 9:00 - 17:00 for a month. During each odour assessment,
weather conditions were also recorded as relevant information. The odour patrol monitoring
results are expressed in Tables 2 and 3. The results indicate that odour intensity at all the
monitoring locations were not higher than Level 2, unless only once the odour intensity at
Location 3 was between 2 and 3 with a low percentile of 3.3.
