Odour and toxic gas (H2S and NH3) emissions from the intensive livestock operations have become a public concern due to their environmental impact and potential health impact on neighbouring residents. Determining science-based setback distance has become an urgent need. Using odour dispersion model to predict odour plume downwind and then determine reasonable setbacks based on acceptable odour criteria is a scientific approach. Source odour emission rates, which are changing constantly with animal and climatic conations, are the basic data needed for odour dispersion modeling. The diurnal and seasonal odour emission profiles need to be revealed and considered in odour dispersion modeling. Identifying major odour sources will help development and applying odour control technologies targeting major sources. Acceptable odour criteria (such as odour impact index) considering odour intensity, offensiveness, persistence, frequency, etc., need to be established. H2S and NH3 are toxic gases and the major odorants of livestock odour and need to be quantified.

由于环境的影响和对邻近居民的潜在健康影响，强化牲畜行动的气味和有毒气体（H2S和NH3）的排放已成为公众关注的问题。确定基于科学的挫折距离已成为迫切需要。使用气味分散模型来预测气味羽流下风，然后根据可接受的气味标准确定合理的挫折是一种科学方法。源气味发射速率是随着动物和气候锥的不断变化的，是气味分散建模所需的基本数据。需要在气味分散建模中揭示和考虑昼夜和季节气味发射曲线。识别主要的气味来源将有助于开发和应用针对主要来源的气味控制技术。需要确定可接受的气味标准（例如气味冲击指数），需要确定气味强度，进攻性，持久性，频率等。 H2S和NH3是有毒气体，是牲畜气味的主要气味，需要量化。
