Abstract

Introduction: Polycyclic Aromatic Hydrocarbons (PAHs) are one class of chemical products found naturally in crude oil, tar and gasoline. They are also created by the burning of coal, oil, gas, wood, waste and tobacco. These PAHs sources could attach to particles in the air and form airborne particles.Particulate matter with aerodynamic diameters of less than 2.5 mm (PM2.5 or fine particulate matter) is of particular concern since they can penetrate the respiratory system easily when inhaled and deposit deeply into the lungs' bronchioles and alveoli. Objectives: This paper presents a review for literatures obtained from Scopus database from year 2011 to 2021 from countries in SEA region and assess their carcinogenic health risk. Methodology: Literatures are search using the Scopus search engine using the main keyword and filtered the results to only researches conducted in SEA countries. The reported concentrations of polycyclic aromatic hydrocarbons (PAHs) from these literatures were used to calculate health risk assessment using incremental lifetime cancer risk (ILCR) equation. Results and Discussion: The concentration of PAHs in PM2.5 ranged from 0.378 ± 0.348 ng m-3 to 224 ng m-3. The lowest concentration of PAHs in PM2.5 sample was reported in Prince of Songkhla University (Phuket Campus) in southern Thailand while the highest concentration was reported in rural area of Lampang Province in northern Thailand located in Thoen District. Conclusion: The concentration of PAHs in PM2.5 in rural area was higher compared to urban area. The carcinogenic health risks due to inhalation of PM2.5 in the studies reported in SEA were in the acceptable risk level (ILCR < 10-4) Keywords: polycyclic aromatic hydrocarbon, PM2.5, South East Asia, urban, rural
