Pollutant concentrations in ambient air are fluctuating and influenced by the environment self-purification capability, such as by rainfall occasions. This research was done to evaluate ambient air particulate matter 10 (PM 10 ) concentrations in West Sumatra Province during rainy season. Data from four sampling locations were collected, in which two of them were collected by automatic data collection in air quality monitoring station (AQMS) located at a roadside in the front yard of West Sumatra Governor Office, and Global Atmosphere Watch (GAW) located at a background concentration area in Bukit Koto Tabang. Meanwhile, data in two other locations were collected by using a low volume air sampler. These two locations represent industrial area that is adjacent to a cement factory, and a campus area that is located nearby an agricultural area. The measurement results show that the highest PM 10 of 68.71±10.99 µg/Nm 3 was measured nearby the cement production plant, which exceeded World Health Organization (WHO) threshold for 24-hour measurement. However, it is still below the Indonesian National Ambient Air Quality Standard (NAAQS). On the other hand, the rest locations still met both standards, i.e. 13.20±3.11, 28.60±13.97, and 33.85±8.41 µg/Nm 3 , at the background concentration area, Governor Office, and the campus area, respectively.
