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 SO2 and NO2 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 NO2 and SO2 averages of passive sampler was 29.65 mu g/m(3) and 21.01 mu g/m(3) for exposures of 2-weeks at an industrial site. The maximum monthly concentration for SO2 was observed at the 10th measurement station with 44.19 mu g/m(3) for August. The maximum monthly concentration for NO2 was observed on the 3rd measurement station with 42.83 mu g/m(3) for November. A negative correlation between nitrogen dioxide concentrations and temperature (R-2 = -0.5489) was estimated. A positive correlation between nitrogen dioxide measurement with passive sampler and continuous measurement (R-2 = 0.6571) was estimated.
