During the past two decades, odour emission from intensive animal production farms has topped the list of public concerns due to their environmental impact and potential health impact on neighbouring residents. Maintaining appropriate separation (setback) distances is an economic and effective way of mitigating odours. So far there is no setback model that can give convincing result. The top two reasons are a) the livestock odour properties have not been well understood and the relationships of the odour concentration and intensity were not obtained with reliable approaches thus the odour dispersion models that predict odour concentrations cannot be validated against field receptor measured odour intensities, and b) there are not science-based community odour impact criteria so the setback cannot be determined.

在过去的二十年里，集约化动物生产农场的气味排放由于其对环境的影响和对邻近居民的潜在健康影响而成为公众关注的首要问题。保持适当的间隔（后退）距离是一种经济有效的减轻气味的方法。到目前为止，还没有一个挫折模型能给出令人信服的结果。最主要的两个原因是：a）尚未很好地了解牲畜气味特性，并且未使用可靠的方法获得气味浓度和强度的关系，因此预测气味浓度的气味扩散模型无法根据现场受体测量的气味强度进行验证，以及B）没有基于科学的社区气味影响标准，因此无法确定挫折。
