ENVIRONMENTAL HEALTH RISK ANALYSIS STUDY

Air pollution today is believed to have contributed not a little to the increasing incidence of diseases related to breathing, especially big city. The main cause of air pollution is exhaust particulates and dust from the activities of public and private transport. The results of ambient air measurements in the terminal Giwangan city of Yogyakarta in 2007. By the Environment Agency of Yogyakarta for 24 hours showed a concentration parameter of 202.39 ug/m3 dust and SO2, and NO2 ug/m3 at 289.87 for 139.38 ug/m3 (4. This shows that each of these substances contaminants have been close to the quality standard (BM), which required 230 ug/m3 dust, SO2 and NO2 365 ug/m3, 150 ug/m3. Although the concentration of contaminants still meet quality standards, does not mean the risk to health. purpose of this study was to analyze Environmental Health Risk Exposure Dust, SO2, NO2 due to transport in Yogyakarta Giwangan terminal. This study used an observational analytic approach with cross sectional design, as respondents 30 PKL with the main criteria is not in the habit meroko; smoking and no history of lung disease / respiratory tract infections . variable is the concentration of research TSP, SO2, NO2 as an independent variable and the dependent variable lung capacity. Data collected in the test with Product Moment Correlation or Spearman Rank Test and the prediction of the risk exposure of TSP, SO2, NO2. results of this study concluded that nearly half respondents lung capacity (FVC, FEV1/FVC) has declined to the assumptions considered abnormal and largely unknown risks RQ intake TSP, SO2, NO2 is still below the threshold of the estimated daily exposure dose (RFC). Results Rank spearmen analysts note SO2 intake correlated significantly of lung capacity and FVC FEV1/FVC Giwangan terminal vendors, while the intake TSP, NO2tidak relate meaningfully. results of risk analysis for the prediction of life time exposure (30 th). concentration of TSP, SO2, measured in the air terminal NO2yang Giwangan, if assumed to be fixed and exposes PKL continuously based on their exposure to the duration of the next 30 years, has increased the probability of the majority of street vendors to be exposed to respiratory disorders.
