| Abstract |
This study aims to investigate the distribution pattern and the health risk assessment of PM2.5 in the Thailand atmosphere. Data used from initially PM2.5 monitoring station of 5 cities in Thailand that different major source of polluted PM2.5 recorded data during January 2014 to December 2017 were observed. The findings shown that average concentration ranged from 1 μg/m3 to 247 μg/m3, highest in Saraburi. The diurnal patterns shown highest peak concentrations at 08.00 – 09.00 am and lowest at 02.00 - 04.00 pm. Due to weekly pattern the concentrations in weekday were likely more than weekend. The seasonal patterns comparation was highest in winter and lowest in rainy. For the potential health risk analysis the population were divided into four age group (children 1-5 years, children 6–11 years, children 12–19 years and adults 20 and over). The health risk analysis was considered age-specific respiratory rates and body weights for different age group. There were shown that negative health effect for all age group, especially cement plant area (Saraburi), urban (Khon Kaen), coal power plant (Mae-Moh), industrial area (Rayong) and Moon soon area (Hat-Yai) respectively. The children 1-5 years group had the highest health risk, children 6-11 years, children 12-19 years and adults respectively. This study concluded that PM2.5 is still a challenging environmental health problem for Thailand and is a risk to public health. Knowing the distribution patterns helps policymakers to plan solutions. |
