HEALTH AENV SIRS 79 – 89 minimum odour threshold of the individual constituent is likely to be a conservative estimate for the chemical group. Section 14.1 The possibility that some individuals might detect nuisance odours from a few of the COPCs cannot be entirely dismissed. The following factors need to be considered: • A large majority of the COPCs that exceeded their respective minimum odour thresholds have very low odour thresholds and distinctive odours, making them very recognizable. • The presence of individuals possessing a “keen” sense of smell is possible. Women and children often have a remarkable sense of smell and can detect and distinguish odours at low levels. • Individual variables, such as breathing patterns, state of physical health, past experiences and state of awareness, can have a considerable bearing on the detection of odours. Despite this, the exceedances of the minimum and mean odour thresholds (in the case of the aliphatic aldehyde group at Cabin K) must be viewed in light of the conservative assumptions incorporated in the assessment and with full consideration of the complexity of the sense of smell which is influenced by individual, environmental, and substance-based factors. In addition, potential odours associated with these COPCs are likely to be sporadic, rather than continuous. April 2010 Shell Canada Limited 14-11 CR029
