STUDY OF AIR ALLERGY FROM PARTICULATE MATTER 10 MICROMETERS (PM10): A CASE STUDY OF EASTERN ECONOMIC CORRIDOR (EEC)

Abstract

The purpose of this research was to study the distribution of PM10, to investigate the areas at risk of air allergy from PM10 and to examine the trends of air allergy caused by PM10 a case study of Eastern Economic Corridor (EEC). By using statistical data of the past 5 years (2014-2018) and Geographic Information System (GIS) for Interpolation with Inverse Distance Weighted (IDW) method from the 3 provinces of air measurement stations, the areas of study included Chachoengsao Province, Chon Buri Province and Rayong Province for PM10 dispersion. It was to analyze the risk areas of PM10 allergy by studying dust sources and dust distribution as well as Time series analysis for graphs showing trends in air allergy in 2019.

The results of the study showed that PM10 dispersion was more dispersed in Chon Buri and Rayong province than Chachoengsao province. As for the study of PM10 risk areas, it was found that there was a total of 31 dust sources, 28 industrial plants, 3 stone mills, and the main roads used for transportation consisting of Chachoengsao province of 15 lines, Chon Buri province of 14 lines and Rayong province of 7 lines. In addition, as the trend of air allergy from PM10 using a 5- year monthly retrospective statistic for the model Winters' multiplicative analysis, it was found that the MAPE value was 0.829, which was less than 30%. It was as significant as 0.719, which was greater than 0.05, occurring unnaturally. The trend rate of air allergy patients from PM10 on 2019 had decreased to 5,071 cases.
