The impact of industrial air pollution in areas not specifically designated for industrial areas:

Concentrated industrial areas have the potential to contribute to ambient air pollution in the surrounding area. This research aims to analyze the impact of industrial activities on total particle concentration and element content with diurnal variations in the measurement time. The study location was conducted in an industrial area in Tempuran District, Magelang Regency, Indonesia. X-ray Fluorescence (XRF) devices were used to analyze element content in collected particulate both in emission and ambient measurements. Based on the emission measurement, for several industries, emission standards were met, but the flow rate of emissions in identified stacks was quite low so there was not enough dilution in the atmosphere. TSP concentrations showed concentrations 2 times higher at site closest to industrial area compared to farther site during the day and at night. However, the percentage of major elements to TSP during the day compared to the night at three sites in general was comparable. Based on the EF analysis, the components classified as slightly enriched are P, Fe, Na, and Cu. The S component is enriched, while the Cl component is very enriched. Based on the results of the dispersion model, the distribution of emissions is more concentrated at nighttime than during the daytime. The number of patients with acute respiratory infection in affected areas is 5–12 times higher than that of unaffected areas. This indicates the accumulative impact of air pollution even though the ambient air quality standards for particulate parameters are met.
