Analysis of environmental health risk due to exposure to sulfur dioxide (SO2) and nitrogen dioxide (NO2) in the industrial area of PT. Tonasa cement

Abstract

Background. The dominant emissions generated from the cement manufacturing process are particulate matter in the form of dust and gases such as SO2 and NO2. Sources of Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2) gas exposure in cement plants can be found in production units, such as reclaimer, raw mill, combustion (pre-heater, rotary kiln, and cooler), finish mill, and packhouse.Objective. The purpose of this study is to determine the public health risks and spatial patterns of Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2) exposure in people living around the industrial area of PT Semen Tonasa. Methods. This research is a descriptive quantitative study that uses the environmental health risk analysis (EHR) study method. The research location and sampling sites were in 8 areas, namely Mangilu Village, Biring Ere Village, Sapanang Village, Samalewa Village, Bulu Cindea Village, Bowong Cindea Village, Bontoa Village, Taraweang Village, Pangkajene Islands Regency (Pangkep). A total of 160 respondents (consisting of 80 children and 80 adults) and 8 ambient air samples were examined at PT Global Quality Analytical. Data analysis was carried out by calculating the intake value, and RQ. If RQ> 1 then risk management is carried out. Results. This study shows that there are no locations that exceed the quality standards for SO2 and NO2 concentrations. With an average exposure frequency of 358 days per year and an exposure duration of 30 years, the children's inhalation rate is 0.5 m3 /h d.
