Assessment of the Contribution of Local and Regional Biomass Burning on PM2.5 in New York/New Jersey Metropolitan Area by Subraham Singh, Glen Johnson, David W. DuBois, Ilias G. Kavouras

“…Abstract The sources of fine particulate matter (PM2.5, particles with diameter < 2.5 µm) in four monitoring sites in the New York/New Jersey metropolitan statistical area from 2007 to 2017 were apportioned by positive matrix factorization (PMF) of chemical speciation data. Biomass burning, secondary inorganic (i.e., ammonium sulfate and nitrate) and primary traffic exhausts were the predominant PM2.5 sources. …”

Transformation and fate of Fe(III) in petroleum-hydrocarbon-contaminated soil and groundwater by Essouassi Elikem, David Bulmer, Kris Bradshaw, Ardalan Hayatifar, Matthew B. J. Lindsay, Steven D. Siciliano, Derek Peak

“…Colloids in the groundwater (solid particles retained on a 0.45 $$\upmu$$ μ m filter) and soil cores were collected from the site. Fe speciation in these samples was characterized using X-ray absorption near edge structure (XANES) and Fourier transform infrared (FTIR) spectroscopy. …”

Assessment of Impact of Meteorology and Precursor in Long-term Trends of PM and Ozone in a Tropical City by Christian Mark G. Salvador, Angeles D. Alindajao, Karen B. Burdeos, Mark Anthony M. Lavapiez, Jhon Robin Yee, Angel T. Bautista, Preciosa Corazon B. Pabroa, Rey Y. Capangpangan

“…The max concentrations of aerosol occurred during the dry season when the loss of particles through wet deposition was limited. Speciation of PM2.5 indicated that fine aerosol was dominated by sea salt and organic matter (OM). …”

Machine Learning Classification Model to Label Sources Derived from Factor Analysis Receptor Models for Source Apportionment by Vikas Kumar, Vasudev Malyan, Manoranjan Sahu, Basudev Biswal

“…In this study, a machine learning (ML) classification algorithm, k-nearest neighbour (kNN), is applied to the source profiles obtained from the United States Environmental Protection Agency’s (U.S. EPA) SPECIATE database to develop a model that can automatically label the factors derived from FA receptor models. …”
