公众向监管机构提出的大多数空气污染投诉都是由气味排放引起的。需要制定方法来客观地了解气味的影响，以便产生气味的设施有一个主动的手段来减少它们对周围社区的影响。这些方法必须考虑气味在浓度范围内的亚阈值和超阈值效应，当气味扩散到一个社区时，可以体验到这些效应。此外，传统的弥散模式可以适应当地气象和地形条件的影响。然而，需要制定气味影响的度量标准，考虑到气味在受体的浓度和频率，以及这些受体的人口密度。本文提出并演示了六个影响参数的使用，这些参数可以用作衡量固定气味源对社区影响的指标。这些气味影响参数是最大浓度、最大响应概率、足迹面积、浓度加权足迹面积、概率加权足迹面积和人口影响。通过评估这些参数来量化产生气味化学物质的工业设施的影响，证明了这些参数的效用。(c) 2005 Elsevier Ltd版权所有。
Odorous emissions are the cause of most air pollution complaints that are made by the public to regulatory agencies. Methods need to be developed to objectively access the impact of odours so that odour-producing facilities have a proactive means of reducing their impact on surrounding communities. These methods must consider the sub- and suprathreshold effects of odour over the range of concentrations that can be experienced as the odour disperses over a community. In addition, the influence of local meteorological and terrain conditions can be accommodated through conventional dispersion models. However, metrics of odour impact need to be developed which take into account the concentration and frequency of odours at receptors, as well as the population density at those receptors. This paper proposes and demonstrates the use of six impact parameters that may be used as metrics of the impact of a stationary odour source on a community. These odour impact parameters are maximum concentration, maximum probability of response, footprint area, concentration-weighted footprint area, probability-weighted footprint area and population impact. The utility of these parameters were demonstrated by evaluating them to quantify the impact of an industrial facility that produces an odorous chemical. (c) 2005 Elsevier Ltd. All rights reserved.
