Abstract
The impact of industrial activities on air quality has been assessed by collecting APM samples using a Gent stacked filter unit sampler from 2018-2020. Monitoring was conducted in three locations around industrial sites in East Java Province, Indonesia. Industrial impacts were identified from the PM2.5, BC and elemental concentrations, especially heavy metals such as Pb, Fe, and Zn, which were higher than in other cities in Java. The comparison of PM2.5 and PM10 in the industrial areas of other cities will also be presented. Black carbon concentrations showed that BC in industrial areas was higher than in cities in other parts of Java because of coal use as a major fuel. Characterization results show that the main elements in APM were S, K, crustal elements (Al, Si, and Ca), and heavy metals (such as Fe, Zn and Pb). Comparison of heavy metals in industrial sites and in other cities in Java showing the levels of heavy metal pollution will also be discussed. The results of several APM samples at industrial sites showed high Pb concentrations (exceeding 1 µg/m3), as well as Fe and Zn concentrations that were at a higher level than other cities in Java. These results agree with source apportionment results where the source profiles show the presence of a Cu metal industry, a Pb smelter, a Zn industry, and a steel industry. These results illustrate the contribution of the activities of various types of metal industries around the sampling locations. The results obtained indicate the importance of detecting pollution early so that the results can be used as a reference in formulating appropriate policies and avoid greater impacts later.
