Four main scenarios of the frequency of the odour pollution were assessed. These were once
a day, once a week, once a month and the whole day. The survey found that the smell would
eventually disappear but the rate of disappearance was uncertain and perceived by 41.0% of the
respondents as dependent on the general weather situation. In this vein, 9.5% thought the
direction of the wind was the main determinant while 3.7% attributed it to the heat. In responding
to the foul smell eventual disappearance, 15.3% said it happened after more than six hours
followed by one to two hours (17.4%) and three to four hours (11.1%).
