This paper describes part of a comprehensive National Air Emissions Monitoring Study (NAEMS) conducted at a swine finishing farm located in the state of Indiana, in the United States. The NAEMS was a 2-year study of emissions from animal feeding operations that produce pork, chicken meat, eggs, and milk. It provided emission data for the US. Environmental Protection Agency (EPA) to develop tools for estimating emissions from livestock farms. The study in Indiana focused on quantifying and characterizing emissions of gases, particulate matter (PM), and volatile organic compounds (VOCs) from a swine finishing quad (four 1000-head rooms under one roof). Long-term continuous and quasi-continuous measurements were conducted with 157 on-line measurement variables using an array of instruments and sensors for gas and PM concentrations, fan operation, room static pressures, indoor temperature and humidity, animal activity and feeding times, and weather conditions. Pig inventory and weight, feed type and quantity, and manure accumulation and composition were also documented. Systematic tests of the measurement system were conducted. Monitoring methodologies, instrumentation applications, equipment maintenance, quality controls, and system performances are presented and can be used as a reference in assessing research quality and improving future environmental studies on livestock facilities.
本文介绍了在美国印第安纳州进行的一项全面的国家空气排放监测研究（NAEMS）的一部分。NAEMS 是一项为期两年的研究，研究对象是生产猪肉、鸡肉、鸡蛋和牛奶的动物饲养场的排放。它为美国环境保护署（EPA）提供了牲畜养殖场排放估算工具的开发数据。印第安纳州的研究重点是量化和描述来自一个猪育肥四联体（一个屋顶下的四个 1000 头猪舍）的气体、颗粒物（PM）和挥发性有机化合物（VOCs）的排放。使用一系列仪器和传感器，对 157 个在线测量变量进行了长期连续和准连续测量，用于测量气体和 PM 浓度、风扇运行情况、房间静压、室内温度和湿度、动物活动和喂食时间以及天气条件。猪的存栏量和体重、饲料类型和数量以及粪便积累和组成也有记录。还对测量系统进行了系统测试。本文介绍了监测方法、仪器应用、设备维护、质量控制和系统性能，可作为评估研究质量和改进未来关于牲畜设施的环境研究的参考。
