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.

在过去的二十年中，由于环境的影响和对邻近居民的潜在健康影响，密集动物生产农场的气味排放占公众关注的榜首。保持适当的分离（挫折）距离是减轻气味的经济有效方法。到目前为止，还没有挫折模型可以带来令人信服的结果。最高的两个原因是a）牲畜气味的特性尚未得到充分了解，气味浓度和强度的关系未通过可靠的方法获得，因此无法验证异味分散模型无法验证异味浓度，无法针对现场受体测量的气味强度验证，b）不能确定基于科学的基于科学的社区异味标准。
