DOI: 10.1007/s13762-017-1265-7

Abstract: Fine particulate matter (PM2.5) and volatile organic compounds (VOCs) coexist in ambient air and contribute to adverse health effects in human populations. Thus, it is helpful to identify the contributions of air pollutants from different… read more here.

DOI: 10.1016/j.atmosenv.2018.10.037

Abstract: Abstract This study developed a receptor model, comprising four non-negative matrix factorization algorithms: the multiplicative update method; the optimal gradient method; the highly efficient, monotonic, fixed-point method; and the conjugate gradient method. The feasibility and… read more here.

DOI: 10.1016/j.atmosres.2017.02.008

Abstract: Abstract Several source apportionment studies considering multiple sites showed spatial variability of source contributions. However, setting up multiple fixed sites to collect comprehensive chemical speciation data is resource demanding. In this study, field campaigns were… read more here.
