(2023-01-11)The need for higher rated emission factors due to increasing regulation of particulate matter by the EPA led to a previously conducted study that developed new emission factors for all point sources at cotton gins. However, ...

Engineering approaches to address erros in measured and predicted particulate matter concentrations (Texas A&M University, 2006-08-16)Some of the air pollution regulations in the United States are based on an application of the National Ambient Air Quality Standards at the property line. Agricultural operations such as cotton gins, feed mills, and cattle ...
-
(Texas A&M University, 2004-09-30)Agricultural operations across the United States are encountering difficulties complying with current air pollution regulations for particulate matter (PM). PM is currently regulated in terms of particle diameters less ...
-
(2016-08-10)Traffic-related air pollution (TRAP) contributes significantly to overall ambient air pollution, and exposure to TRAP has been implicated in the development of an array of disease states, including asthma, chronic obstructive ...
-
(2017-02-21)Air pollution, especially particulate matter (PM), is of growing concern in the United States and around the world. PM with aerodynamic diameter (AED) less than 2.5μm is currently one of the two indicators for PM pollutions. ...
-
(2022-12-05)PM2.5 concentrations are monitored at ground stations and are often geographically sparse. Machine learning (ML) methods, and more conventional statistical models, have been used to estimate PM2.5 from aerosol optical depth ...
-
(2015-05-05)Quantitative information on sources and source region contributions to particulate matter (PM) concentration in China is currently poorly understood but is urgently needed to make emission control strategies. In this study, ...
-
(2009-05-15)Poor regional air quality in some states across the US cotton belt has resulted in increased pressure on agricultural sources of particulate matter (PM) from air pollution regulators. Moreover, inaccurate emission factors ...
