description | 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. The results showed that the 24-h fine fraction PM(2.5) concentrations were 24.1 ± 12.2 μg/m(3) and 63.0 ± 18.7 μg/m(3) in the rainy and dry seasons, respectively. The results indicate that the size distributions of the particles of 2.0–2.5 μm are minor, and the majority are ultrafine particles with aerodynamic diameter ≤ 1.0 μm. Overall, the mass concentration level of the water-soluble fraction of trace metal(oid)s in PM(2.5) in the rainy season was higher than that in the dry season. Among these, Ca, K, and Na were the most abundant earth crustal elements in PM(2.5) in the rainy and dry seasons, accounting for 85% and 41.2% of the total trace element concentrations, respectively. The major sources of PM(2.5) are local and regional sources of thermal power plants, industrial parks, and waterborne transportation (domestic rivers and marine). The activities undertaken to remove Agent Orange (e.g., soil excavation, transportation, and rotary kiln incinerators) at the Bien Hoa airbase area also cause increases in the PM(2.5) level in the atmosphere of Bien Hoa City.
