Risk Model of Exposure to Air Pollution (No2, So2, TSP and Dust) on Pulmon Function in Traffic Police in Palembang City

Abstract

Increasing volume in the vehicle lane it will increase the concentration of SO2, NO2, TSP, and Dust on the roadside both outdoor and indoor. The Police Officer of the Street Officers has a high level of exposure to motor vehicle gas emissions because they are people who throughout their work are always on the highway, so they will often be exposed and can interfere with health, especially the health of the respiratory system. The research aims to model air pollution exposure to lung function in traffic police. This study uses a cross sectional risk analysis design to estimate non cancer hazard index (HI) health risk by dividing the intake (I) value with References Concentration (RfC) and making a risk management model. Broadly speaking, the research was carried out in 4 important stages, namely, the first stage of the initial survey and field observations on 100 traffic police in Palembang City selected proportionally random sampling for the initial risk assessment data collection, the second stage Spirometry measurements and selected air sample data collection (NO2, SO2, TSP, Dust), and the third stage of laboratory analysis and spirogram reading, and the fourth stage Modeling of risk factors Exposure to air pollution to lung function capacity in Traffic Police. The average concentration of pollutants in the air = NO2: 0.478 mg / m3; SO2: 0.856 mg / m3; TSP: 7.810 mg / m3; PM10: 3,591 mg / m3. Lung capacity of traffic police, average FEV1: 2.81 L and FVC: 3.63 L. Realtime exposure assessment NO2: 0.055; SO2: 0.923; TSP: 2,943 and PM10: 4,8. The model of exposure to air pollution is needed to control the health effects of NO2, SO2, TSP and PM10. Control modifies the standard or quality standard, where the HI value or Hazard Index that exceeds 1 can be controlled by controlling the intake value (I) inhalation of NO2, SO2, TSP and PM10
