Assessment of concentrations and emissions of airbourne pollutants at various poultry operations

农业部门是颗粒物、氨和温室气体(如甲烷和一氧化二氮)的来源，这些气体被排放到大气中，导致空气质量下降和气候变化。家禽部门正在对其环境管理采取积极主动的方法，并已将了解其大气排放作为高度研究优先事项。这项建议旨在通过测量过程中的排放量和细小颗粒物、氨、温室气体以及来自各种家禽舍作业、粪便储存设施和土地应用活动的其他气态污染物来解决这一研究优先事项。将采用系统方法，跟踪谷仓产生的粪便的生命周期，直至其储存和最终的土地应用，以便为整个农场作业生成大气排放的综合视图。这种完整的农场方法将允许探索和制定最佳管理做法，以平衡农业企业排放的一系列空气污染物的短期收益和长期收益。

The agriculture sector is a source of particulate matter, ammonia and greenhouse gases, such as methane and nitrous oxide, that get emitted into the atmosphere and contribute to poor air quality and climate change. The poultry sector is taking a proactive approach to their environmental stewardship and has made understanding their atmospheric emissions a high research priority. This proposal aims at addressing this research priority by measuring emissions of the course and fine fractions of particulate matter, ammonia, greenhouse gases as well as other gaseous contaminants from various poultry housing operations, manure storage facilities and land application events. A systems approach will be employed by following the life cycle of the manure generated in a barn through to its storage and eventual land application such that an integrated view of the atmosphere emissions can be generated for the whole farm operation. This whole farm approach will allow best management practices to be explored and developed that balance short term gains against longer term benefits for a suite of air contaminants emitted by the farming enterprise.
