Air Pollution and Lung Capacity of People Living around the Cement Industry

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.

Risk Factors of Death Due to Corona Virus Disease 19 in Kendari City

“…The high death rate from coronavirus disease-19 is caused by several factors such as individual factors. Individual factors include age, biologically the elderly population will experience the aging process which is characterized by decreased body resistance, congenital or comorbid diseases (7). This can make the body more susceptible to disease.…”

Decreasing Level of Plumbum (Pb) Chromium (CR) In Sea Water With Soil Layer Media (Montmorillonite)

“…Human activities, such as industrial production, mining, agriculture and transportation, release large amounts of heavy metals to the surface and ground water, soil and finally to the biosphere. Pollution occurs almost in all over the world and all elements, both air pollution that endangers health [3] and water pollution that has implications for public health [4]. The high level of pollution that occurs, especially in sea water is the implication of the consequences of human activity on land, specifically due to contamination of heavy metals [5] in developing countries [6].…”

“…Pollution almost happens in all over the world and elements, such as air pollution that harms people's health [1] and water polution that implicates public health [2]. The contamination of heavy metals through aquatic ecosystem has become a problem in environmental health for several decades [3], [4].…”
