Interpretive Summary:

Technical Abstract: Agricultural facilities are the source of many types of particles and gases that can exhibit an influence on air quality. Emissions potentially impacting air quality from agricultural sources have become a concern for various state and federal regulatory agencies. Particle mass concentration influences from agricultural sources can include both primary particles (direct emissions such as dust) and secondary particles (formed from gaseous precursors such as ammonia). In support of other investigations at several producers in California, continuous measurements of particulate size and composition were obtained via an aerosol mass spectrometer. Facilities studied included a several hundred head dairy, a cotton producer, and an almond orchard. A single trailer was equipped with an aerosol mass spectrometer and other supplemental instruments including a PM2.5 carbon analyzer and an eight-stage cascade impactor. This suite of instrumentation allowed characterization of a wide range of particulate properties.
