A Case Study of PM2.5 Characterization in Bangi, Selangor, Malaysia during the Southwest Monsoon Season

“…Since the Recommended Malaysian Ambient Air Quality Standards (RMAAQS) of PM have been established for particulate matter with diameters ≤ 10 µm (PM 10 ), total suspended particles, and lead (Pb), many reports have presented data regarding these forms of PM (Abas and Simoneit, 1996;Fang et al, 1999;Okuda et al, 2002;Abas et al, 2004a, b;Omar et al, 2007;Norela et al, 2013;Wahid et al, 2013;Jamhari et al, 2014). Particulate matter with diameters ≤ 2.5 µm (PM 2.5 ) has a higher health risk than PM 10 due to its ability to penetrate deep into the respiratory tract, longer transport distance and longer residence time in the atmosphere.…”

The state of ambient air quality in Pakistan—a review

“…, Bangladesh (Begum et al 2006), 69 Thailand (Oanh et al 2006;Oanh and Zhang 2004/06), 70 Philippines (Cassidy et al 2007;Oanh et al 2006), Malaysia 71 (Omar et al 2007), Korea (Pandey et al 2008), Vietnam 72 (Oanh et al 2006), Indonesia (Oanh et al 2006), and China (Shaheen et al 2005a).

Occurrence and Distribution of Aliphatic and Polycyclic Aromatic Hydrocarbons in Surface Waters along Coastal Area of Suez Gulf

“…Moreover, Benzo [a] pyrene (BaA), the most carcinogenic pollutant of all PAHs (58) reveals values ranged between 0.378 and 98.763 ng /L, (Table 5). A study supported that the phenomenon of BP emission coming from engines (61) . The study mentioned that the highest abundance of BP was recorded at S.NO.9 which found vicinity to EL-Sukhna of Loloh beach where, the tourism boats and ships activities along the Suez Gulf and that incomplete fuel combustion was its source.…”

“…The high-molecular-weight PAHs of four rings (FIu, Pyr, BaA, and Chr), five rings (BbF, BkF, BaP, and DahA) and six rings (IP, BP) were dominated by HMW-PAHs (4-6 rings), representing the range of 0.085-100%, which are likely derived from anthropogenic activities (61) such as incomplete fuel combustion of the boats, ships, and vehicle engines. However, the lower-molecular-weight PAHs of two rings (Nap) and three rings (Ac, Ace, F, Phe, and Ant) made up zero and 99.917% of the total PAH concentrations, respectively.…”
