Abstract

Background: The cement industry is one of the main contributors of pollutant gasses in the environment through stack emissions.Aim: This study aims to model the dispersion of SO2 and NO2 gasses and to determine the area of the dispersion by American Meteorological Society – Environmental Protection Agency Regulation Model or AERMOD has been utilized by PT. Semen Tonasa (Tonasa Cement, Ltd.).Methods: Meteorological data from AERMENT was collected from reanalysis of MM5 data. While topographical data was extracted from SRTM30 satellite data. The model was carried out for a year, to cover both the dry and rainy season.Results: The result of the modeling showed that the peak value of the concentration of SO2 and NO2 pollutants for one hour are 135 μg/m3 and 160 μg/m3 respectively (quality standards of SO2 and NO2 are 900 μg/Nm3 and 400 μg/Nm3). The area of dispersion tends to be in the eastern area, such as District Minasatene (Sub-district Bontoa, Kalabbirang, Minasatene dan Biraeng), District Bungoro (Sub-district Biringere, Sapanang, Mangilu, Bulu Tellue) and District Labakkang (Sub-district Taraweang). Key words: Spatial analysis, AERMOD, AERMOD, cement factory, exposed area, SO2 and NO2

Abstract

Background: Some internal factors have both positive and negative effects to people's health, especially those who live in a polluted area. The area around the cement industry is an example of polluted area in which the lung capacity will be harmed.Aim: This research aimed at finding out internal factors affecting lung capacity of people living in the area around the cement industry.Methods: This research used a cross sectional study plan by measuring lung capacity (FEV1 and FVC) of people living in four different locations. The locations were based on wind directions and within 3 km from the cement industry. The study plan was also done by connecting the measurement with other factors, such as age, physical activities, nutrition status and passive smoking or environmental tobacco smoke (ETS).Results: Based on the calculation of lung capacity 241 respondents obtained 123 respondents (51%) had a normal lung capacity, 105 respondents (43.6%) had a restricted lung capacity, 4 respondents (1.7%) had an obstructed lung capacity and 9 respondents (3.7%) had a combination of a restricted and obstructed lung capacity. The age (p=0.977) and physical activities (p=0.087) of respondents had no effect on the lung capacity. However, nutrition status (p=0.011) and passive smoking or ETS (p=0.003) do.Conclusion: The nutrition status and the presence of a passive smoker were the internal factors affecting people's lung capacity, especially for those who live around the cement industry. Thus, in order to avoid the impairment of lung capacity, people need to improve their nutrition and to avoid people smoking around them.

Abstract

Backgrounds: A cement industry is one of anthropogenic sources of air pollution. In polluting the air, the industry creates some dust particles, nitrogen oxide (NO2), sulfur oxide (SO2), and carbon monoxide (CO).Research Purpose: The research aims at finding out the ambient air quality around a cement industry and relating it with the lung capacity of people living around the area.Methodology: This research uses cross sectional studies by measuring the ambient air quality in the morning, noon, and evening in four different settlements within 3 km from the cement industry. The measurement is then correlated with the FEV1 and FVC of lung capacity of people living around the area.Result: Of all four locations, three have ambient air quality (PM2.5 = 109.47 µg/Nm3, TSP = 454.7 µg/Nm3) that surpass the quality standard (PM2.5 = 65 µg/Nm3, TSP = 230 µg/Nm3). Of 241 respondents, the average level of FVC and FEV1 is respectively 1.9352 liter (SD: 0.45578) and 1.7486 liter (SD: 0.43874). Furthermore, the level of PM2.5 in the morning and at noon is respectively p=0.009 and p=0.003; the level of TSP in the morning and at noon is respectively p=0.003 and p=0.01; the level of NO2 in the morning is p=0.006; the level of SO2 in the morning, at noon and in the evening is respectively p=0.000, p=0.022, and p=0.000; and the level of CO in the morning, at noon and in the evening is respectively p=0.003, p=0.015, and p=0.024. Those levels are associated with the level of respondents' FEV1. Moreover, the level of TSP in the morning is p=0.024; the level of SO2 in the morning and in the evening is p=0.007. These levels relate to the level of respondents' FVC.Keywords: FVC, FEV1, CO, NO2, SO2, TSP, PM2.5, cement industry.
