Physico-chemical properties and transboundary transport of PM_2.5 in Bien Hoa City, Dong Nai Province, Southeastern Vietnam.

ABSTRACT: Air pollution is one of the most concerning environmental issues, wherein PM_2.5 concentration plays an important role. This study monitored and evaluated the PM_2.5 concentration trends in Bien Hoa City, Dong Nai Province, Vietnam. Twenty 24-h PM_2.5 samples were continuously collected during the rainy (15 Oct. to 25 Oct. 2021) and dry (19 Mar. to 29 Mar. 2022) seasons. The PM_2.5 samples were analyzed by scanning electron microscopy to determine the surface pattern and size distributions were analyzed using ImageJ software. The water-soluble fractions of 15 trace metal(oid)s concentrations (Al, Cu, Ni, K, Ca, Co, Mn, Cr, As, Zn, Pb, Cd, Na, Fe, and Mg) bound to PM_2.5 were analyzed by inductively coupled plasma-mass spectrometry.
