Source Apportionment of Particulate Matter by Application of Machine Learning Clustering Algorithms

نویسندگان

چکیده

A source apportionment (SA) study was conducted on two PM2.5 data sets, carbon fractions and eight temperature-resolved collected during Cincinnati Childhood Allergy Air Pollution Study (CCAAPS). This aimed to evaluate clustering algorithms: k-means (kMC) spectral (SC) as potential receptor models for apportionment. The application of kMC produced unsatisfactory results, but the results obtained from SC demonstrated a significant correlation with using positive matrix factorization (PMF). were associated practical evidence available in literature. identified six factors analyzing set seven set. sources (source contribution parentheses) are: combustion (45.9 ± 3.66%) secondary sulfate (11.4 1.09%), vegetative/wood burning (17.5 1.46%), diesel (10.6 0.92%) gasoline (3.6 0.33%) vehicles, soil/crustal (2.07 0.2%), traffic (9.3 0.81%), metal processing (8.8 0.72%). profiles also show similarity derived PMF. In summary, this presented basic framework applying Machine Learning algorithms SA analysis. Also, it presents model technique SA.

Development and application of a robotic chemical mass balance model for source apportionment of atmospheric particulate matter

An advanced computational procedure is presented for the source apportionment (SA) of airborne particulate matter (PM) using chemical mass balance (CMB) receptor modeling. The so-called “Robotic Chemical Mass Balance” model (RCMB) minimizes personal judgment, by leading straight-forwardly to the bestefit combination of the source profiles that are included in a set of input data. RCMB involves ...

Workgroup Report: Workshop on Source Apportionment of Particulate Matter Health Effects—Intercomparison of Results and Implications

Although the association between exposure to ambient fine particulate matter with aerodynamic diameter < 2.5 microm (PM2.5) and human mortality is well established, the most responsible particle types/sources are not yet certain. In May 2003, the U.S. Environmental Protection Agency's Particulate Matter Centers Program sponsored the Workshop on the Source Apportionment of PM Health Effects. The...
