Crustal fraction of cattle feedlot particulate matter emissions using neutron activation analysis: method development Academic Article uri icon


  • Neutron activation analysis (NAA), along with multivariate statistical methods, were employed as a proposed method to measure concentrations of some 30 elements in filtered air particulates and to estimate the fraction of particulate matter originating from crustal sources. The new method may provide a means for certain agricultural industries, in particular cattle feedlots, to take advantage of the proposed crustal credit in emission regulations, if such a credit is implemented by the US Environment Protection Agency (EPA). Chemical composition of particulate source materials as well as environmental air particulate samples were determined and results compared using computer modelling techniques to determine contribution from each potential source. 2009 Akadmiai Kiad, Budapest, Hungary.
