The Creation of Pollution Mapping and Measurement of Ambient Concentration of Sulfur Dioxide and Nitrogen Dioxide with Passive Sampler

Abstract

Background: Measurements of nitrogen and sulfur dioxide using passive sampler over 12 months in Samsun, Turkey, are compared with SO<inf>2</inf> and NO<inf>2</inf> concentrations obtained from a co-located chemiluminescence analyzer. The concentrations of Sulfur and nitrogen dioxide in the ambient air during the period from November 2009 to September 2010 are analyzed. Results: The highest value for annual NO<inf>2</inf> and SO<inf>2</inf> averages of passive sampler was 29.65 μg/m3 and 21.01 μg/m3 for exposures of 2-weeks at an industrial site. The maximum monthly concentration for SO<inf>2</inf> was observed at the 10th measurement station with 44.19 μg/m3 for August. The maximum monthly concentration for NO<inf>2</inf> was observed on the 3rd measurement station with 42.83 μg/m3 for November. A negative correlation between nitrogen dioxide concentrations and temperature (R2 = -0.5489) was estimated. A positive correlation between nitrogen dioxide measurement with passive sampler and continuous measurement (R2 = 0.6571) was estimated. © 2014 Akdemir; licensee BioMed Central Ltd.
