Ambient Air Concentrations of Polychlorinated Dibenzo-P-Dioxins and Dibenzofurans in Ohio: Sources and Health Risk Assessment Ω

Air pollutant gas that has a real impact on the respiratory system is NO2 and SO2. Kalianak Surabaya is one of the areas with high traffic density more than 1.500 vehicles every hour. The most affected communities are the people living along the Kalianak highway. This study aims to analyze the ambient air (NO2 and SO2) in Kalianak and the risk of respiratory distress in the surrounding community. This research is descriptive, with cross sectional approach. The sample of this research is 19 respondents was done by purposive sampling. Spirometers were used to determine the status of lung function. The variables studied were age, length of stay, smoking habit, and Body Mass Index. The collected data were analized with environmental health risk assessment. Environmental Health Risk Assessment showed that the people living in this area unsafe with concentration of NO2 as measured. The results showed that more than 50% of respondents have respiratory problems (68,4%) with the mayority of respondenst aged 46-55 years old (31,6%), leght of stay >20 years (47,4%), non smokers (47,4%), and normal Body Mass Index (36,8%). The conclusion from this research is ambient air quality (NO2 and SO2) in Kalianak Surabaya still meet the quality standard, and the RQ>1 for NO2, it means that the risk level is unsafe. It is recommended that there is an efforts to control air pollution caused by motor vehicle activity by planting planst that can reduce ambient air pollutants.

Chemical Valley

Combined air emissions from multiple petrochemical facilities operating in the area known as Chemical Valley in Sarnia, Ontario, Canada, have led to escalating concerns over health effects to nearby residents. By conducting a quantitative health risk assessment of ambient air data collected from 2008-2014, this thesis investigated whether current emissions are resulting in increased health risk for the population living near Chemical Valley. The results of this analysis are that health risks are slightly higher than levels considered acceptable for large populations, but are within levels often accepted for smaller groups based on the traditional risk assessment - risk management paradigm. Interpreting these results in the context of the literature about the science-policy interface, and environmental dispute resolution, this thesis highlights several problems with using the traditional risk assessment - risk management paradigm as the basis for decision-making in environmental disputes— particularly when the affected population is Indigenous.

Nitrogen dioxide (NO2) is one of the main pollutants that affecting the quality of life and human health. Mostly, the effects of NO2 exposure depending on concentration, duration of exposure and anthropometric variables. This study aimed to analyzing the NO2 concentration of ambient air and to assessing human health risks in real time and lifetime exposure. To achieve that goal, air samples were taken at four strategic locations in Kupang City, in which were represented by industrial, roadside, residential, and office areas. The Griess Saltzman method was used for sampling and analysis of NO2 levels. Totally, there were 48 air samples had been analyzed for NO2 levels. The detected NO2 concentration showed a trend varied between sampling locations. Overall, NO2 levels measured still met ambient air quality standards. Human health risk assessment was carried out by determining the intake (I) and Risk Quotient (RQs) in four groups of individuals exposed to NO2. The results shown that the RQs for real time and lifetime exposures were both less than 1.0, in which implying a non-carcinogenic risk of NO2 exposure in the study area. The results Health risk assessment also indicating that potential non-carcinogenic risks occur when NO2 exposure is more than 39 years.
