The Study of Air Quality and Risk Assessment at the Location of the Planned Railroad Between Makassar-Parepare, South Sulawesi, Indonesia

The National Railway Master Plan, it is stated that the target of developing the railway network in South Sulawesi Province is to connect areas that have the potential for transporting passengers and goods to support the development of integration between districts. The construction of the railway line has the potential to reduce air quality and health risks to the community around the location. This study aims to assess air quality and its risks during the construction of the railway line from Makassar to Parepare as a reference for environmental management and monitoring plan documents. Air sampling was made using multiple impinger and dust with a hi-volt dust sampler and then analyzed in the laboratory and compared with the Air Pollution Standard Index. Analysis of potential pollutants on health was carried out using the Environmental Health Risk Assessment method. The results showed that the air quality at the time of the study was still below the threshold value, and the environmental health risk assessment was still below the value with RQ > 0.1 except for SO2 in adults. The conclusion of the study shows that the air quality at the time of the construction of the railway line is still relatively good, and environmental management and monitoring have been carried out quite well based on the direction of the environmental management and monitoring plan including implementing a green open space management program.
