Source apportionment of acid deposition has now become an increasingly important and significant
tool for current perspectives of acid deposition situation since identification of various source characteristics of
acid deposition is important and necessary for policy makers to implement further control strategies
appropriately. This research study aims to compare the aerosol and rain water components monitoring dataset
collected from different 4 monitoring stations in Thailand from 2001 to 2011 (1. urban site (Public Relation
Department station in Bangkok) 2. rural site (Mae Hia station in Chiang Mai province) 3. industrial site
(Chonburi station in Chonburi province) and 4. rural site (Sakaerat station in Nakhon Ratchasima province)).
The statistical instruments which are the Principal Components Analysis (PCA) and the Positive Matrix
Factorization (PMF) were applied for identifying potential source types and generate modeled source profiles of
acid depositions. The findings of this study could help to comprehend the most potential sources of acid
deposition and their characteristics in different monitoring stations and periods.
