An Assessment of the Relationship between Urban Air Quality and Environmental Urban Factors in Urban Regeneration Areas

Urban air pollution has been increasing due to ever increasing population, rapid urbanization, industrialization, energy usage, traffic density. The purpose of the study is to examine the relation between urban air quality and urban environmental factors in urban regeneration areas. Two common air polluters (SO2 and PM10) are considered in the study. The data are collected for Cigli district, including the level of air pollutants, the local natural gas service lines and planning decisions for the years between 2007 and 2011. According to the examinations, urban environmental factors and planning decisions affect the urban air quality in urban regeneration areas

Examination of the Relationship between Urban Air Pollution and Urban Planning Decisions in Cigli Case, Izmir (Turkey)

The air pollution problem remains, although significant improvements have been seen in urban air quality over the last years. Despite the size and variety of studies on urban air pollution, the usage of spatial statistics has been extremely limited. This study aims to show that the spatial statistic techniques can well be used to examine and explain the air pollution levels in urban areas. The data for the sulphur dioxide (SO2) and nitrogen dioxide (NO2) concentrations are measures using passive diffusion tubes at the 67 monitoring sites in the district of Çiğli (Izmir), which are selected through a spatial systematic sampling process. The tubes were exposed for a 2-week period in August 2015. For the determination of the level of clustering for high values and low values of SO2 and NO2 concentrations, Getis-Ord G* local statistics are calculated. There are five points with high values of SO2 surrounded by low values, three points of NO2, where the results are statistically significant at the 0.10 level. The findings indicate that the presence of the industrial zone, the form of fossil fuels (coal or natural gas) used in heating, and topography are the strong determinants urban air pollution.© 2016.

COPD and urban air pollution GIS based spatial pattern and the geostatistical analysis of Izmir

In Turkey, starting from the 1950's air pollution has been increasing because of rapid population increase, rapid urbanization and industrialization. These cause intense energy usage in settlement areas and this brings some problems in environmental health. The aim of the study is the examination of whether there is any statistical relationship between the level of air pollution with the number of COPD cases and incidence between 2006 and 2010 in Izmir City Center. The study area has six districts of Izmir City Center: Konak, Bornova, Buca, Karsiyaka, Cigli and Balcova. There are in total 89,776 COPD cases between 2006 and 2010. The spatial pattern of these cases is mapped via the GIS environment. Then, multivariate linear regression analysis is performed in the study. Additionally, the questionnaire was realized with 25 COPD inpatients in Dr. S. Seren Chest Diseases Hospital in Izmir in March - April 2014. The results show that there is a significant and positive relationship between the level of air pollution (PM and SO2) and the number of COPD cases and incidence. In general, the increasing of the level of air pollutant and population cause an increase in the number of COPD cases and incidence. It is observed that the level of air quality in Karsiyaka, Bornova and Konak districts is lower than and incidence rates are higher than the other case districts. According to questionnaire results, there is a significant relationship between the inpatients' age and their period of smoking. Also, there are significant relationships among the diagnosis, sex, job, risk factor, genetic predisposition, smoking habits, environment lived in and heating preferences

Evaluation of Air Pollution Effects on Asthma Disease: The case of Izmir

Urban air pollution is undoubtedly a significant risk factor for human health and has been increasing due to increasing population, population density, rapid urbanization, industrialization, traffic density, since the 1950s. The aim of the study is to test the relation between the number of asthma cases and the levels of air pollutants (sulfur dioxide (SO2) and particulate matter (PM10)). The data are collected for six districts in Izmirfor the years between 2007 and 2010. The results from the regression show that there is a statistically significant relation between the number of asthma cases and the level of urban air pollution. (C) 2015 Published by Elsevier Ltd

The Relationship between Respiratory Systems' Cases and Environmental Urban Factors

Air pollution in urban areas which have dense population, industrial facilities and dependence on the private automobiles, adversely affects the number of respiratory system diseases. The aim of the study is to test the relation between the number of respiratory systems cases' and environmental urban factors affecting these cases such as the level of urban air pollution, current land use, total population and the number of vehicles. The data are collected for six districts in Izmir, Turkey for the years between 2007 and 2011. The results show that there's a statistically significant relationship between the number of respiratory systems' cases and environmental urban factors. (C) 2016 The Authors. Published by Elsevier Ltd
