Health Risk Assessment of Particulate matter associated with Polychlorinated biphenyls and Polycyclic aromatic hydrocarbons in Bangkok and Chiang mai, Thailand
การประเมินความเสี่ยงทางสุขภาพจากพอลิคลอริเนตเทตไบฟีนิลและพอลิไซคลิกแอโรแมติกไฮโดรคาร์บอนของฝุ่นละอองใน กรุงเทพมหานครและเชียงใหม่ ประเทศไทย

Abstract:
Atmospheric pollutants have become a severe problem in creating health issues in Thailand. Due to the increase in fine particles in the air environment, the city population is facing acute respiratory problems. For understanding the concentration of polycyclic aromatic hydrocarbon (PAHs) and Polychlorinated biphenyls (PCBs), 24 samplings were done in Chiangmai and Bangkok of Thailand using Polyurethane (PUF) disk passive samplers. There were five sampling sites in Bangkok, and three in Chiang Mai. Data were collected in the dry season from December 2018- June 2019. A total of 24 samples were extracted and further quantitatively analyzed by the standard method using GC-MS. Both PAHs and PCBs concentrations increased during the dry season. In Chiang Mai, the maximum total PAH concentration was found to be 848 ng/m3, which was higher than that of Bangkok, max. concentration was found to be 455 ng/m3. On the other hand, the max of the total PCBs found in Bangkok was 15 pg/m3 were higher than that in Chiang Mai which is max. value 2.63 pg/m3. However, Bangkok sites had more dominant species PAHs than in Chiang Mai. Particularly, during haze episodes of Bangkok and Chiang Mai from December 2018 to April 2019. The potential sources of PAHs were found as the combined emission of diesel and gasoline vehicles and biomass combustion. The carcinogenic risk associated with inhalation exposure to PAHs and PCBs was estimated to be between 10-4-10-6 at some sampling point. It may cause a health effect for people who live in this area for a long term of exposure. The analyzed PAHs and PCBs species indicated their potential sources that related to both biomass burning and traffic in Bangkok and Chiangmai. However, the pollutants' level also had seasonal variations. therefore, air quality management is an essential issue that needs to be monitored in these provinces (cities) of Thailand
