Airborne particulate matter (PM) pollution is a global concern, in which partitioned heavy metals (HMs) could impose great risks to residents living metropolitan areas. In this study, PM10 samples were collected Ho Chi Minh City (HCMC) – megacity southern Vietnam and analyzed for 11 HMs investigate their concentration profiles, perform source apportionment estimate risk factors. Results showed that atmospheric decreased following the order of Al > Fe Sr Mn> Pb Cu Cr V Ni Sb As. Traffic...
Particulate matter (PM) emitted from incense burning is a serious problem because of its effects on human health and the environment, especially air quality Southeast Asia. This study investigated PM1 PM2.5 concentrations in two temples Vietnam Taiwan, focusing events (i.e., new moon full day) non-event days using PM sensors. Moreover, samples were collected to determine organic carbon (OC) elemental (EC) concentrations. The (22.7 ± 18.7 36.5 33.9 µg m-3, respectively) lower than those at...
The application of machine learning and deep in air pollution management is becoming increasingly crucial, as these technologies enhance the accuracy prediction models, facilitating timely interventions policy adjustments. They also facilitate analysis large datasets to identify sources trends, ultimately contributing more effective targeted environmental protection strategies. Ho Chi Minh City (HCMC), a major metropolitan area southern Vietnam, has experienced significant rise levels,...
Concentrations of gaseous elemental mercury (GEM) have been monitored at the Lulin Atmospheric Background Station (LABS; 120.87ºE, 23.47ºN, 2862 m a.s.l.), a high mountain forest site in central Taiwan, since April 2006. A significant decreasing trend GEM rate -1.1% yr-1 (-0.018 ng m-3 yr-1) was found between 2007 and 2022, comparable to trends observed other regions. Multiscale temporal variations concentrations were studied distinguished by application Hilbert-Huang...
Unmanned aerial vehicles (UAVs) have emerged as effective tools for monitoring air pollution across varying altitudes, including assessing atmospheric mercury (Hg) levels. However, studies on the vertical distribution of Hg (i.e., total gaseous mercury–TGM) concentrations remain limited, particularly in Southeast Asia. This study utilized a UAV equipped with TGM sampling device to measure at different altitudes Ben Cat City, an industrial area Southern Vietnam. The purpose this is examine...
Atmospheric mercury (Hg) cycling is sensitive to climate-driven changes, but links with various teleconnections remain unestablished. Here, we revealed the El Niño–Southern Oscillation (ENSO) influence on gaseous elemental (GEM) concentrations recorded at a background station in East Asia using Hilbert–Huang transform (HHT). The timing and magnitude of GEM intrinsic variations were clearly distinguished by ensemble empirical mode decomposition (EEMD), revealing amplitude concentration...
The present study focused on investigating the contamination and risk assessment for 16 metals in street dust from Ha Noi highway, Ho Chi Minh City. results indicated that concentrations of (mg/kg) were found, decreasing order, to be Ti (676.3 ± 155.4) > Zn (519.2 318.9) Mn (426.6 ±113.1) Cu (144.7 61.5) Cr (81.4 22.6) Pb (52.2 22.9) V (35.5 5.6) Ni (30.9 9.5) Co (8.3 1.2) As 2.5) Sn (7.0 3.6) B (5.7 0.9) Mo (4.1 1.7) Sb (0.8 0.3) Cd (0.6 0.2) Se (0.4 0.1). geo-accumulation index (Igeo)...
Since 2013, the Ministry of Natural Resources and Environment published revision “National Technical Regulation on Ambient Air Quality” (QCVN 05:2013/BTNMT), in which fine particulate matter (PM2.5) was added to QCVN. However, status temporal variation PM2.5 Ho Chi Minh City (HCMC) have not been reported so far, especially based continuous high time resolution measurements. The aim this study analyze collected at center HCMC. Based composited data from air monitoring station located...
