HIGHLIGHTS

  • Assessment has been made of urban air quality in 16 Indonesian cities.
  • PM2.5 concentrations on Java generally exceeded the air quality standards.
  • Volcanic eruptions and forest fires produced locally high PM2.5 concentrations.
  • Average BC contributions to PM2.5 ranged from 15–26%.
  • Heavy metal concentrations were significantly higher in Surabaya and Tangerang.
 

ABSTRACT


Assessment of Indonesian urban air quality has been performed over a multiyear period (2010–2017) in sixteen large Indonesian cities covering the islands of Java, Sumatra, Kalimantan, Sulawesi, Maluku, and Papua. Samples of airborne particulate matter (PM) were collected once a week for 24 hrs using a Gent stacked filter unit sampler in two size fractions: < 2.5 µm (PM2.5) and 2.5 to 10 µm (PM2.5-10). These samples were analyzed for mass, black carbon (BC), and elemental composition. The results showed that the majority of the annual concentrations of PM2.5 at the Java sites (Bandung, Jakarta, Semarang and Surabaya) exceeded the annual average Indonesian air quality standard (15 µg m-3), while for other sites, the concentrations were lower than the standards except in Pekanbaru and Palangka Raya. During the forest fires episodes in 2015, the daily concentrations of PM2.5 in Pekanbaru and Palangka Raya exceeded the daily average Indonesian standard (65 µg m-3). The average BC fraction of PM2.5 ranged from 15% to 26%, which indicates BC as major component of the PM2.5 associated with traffic emissions and biomass burning. The distributions of concentrations of major elements in PM2.5 including Si, S, K, Fe, Zn, and Pb varied widely from site to site. All sites have enhanced levels of crustal elements Si driven by unpaved roads and volcanic eruptions, and S contributed from vehicle fuel, forest fires and volcanic emission. The heavily industrialized sites have significantly higher levels of heavy metals (Fe, Zn and Pb – in Surabaya) and (Pb – in Tangerang), demonstrating the impact of the local industrial emission on air quality. These findings represent an important survey of Indonesia’s particulate matter concentrations and compositions, and provide a scientific basis for designing and revising various air quality policies in Indonesia, including an early warning system for severe air quality events.
