The creation of pollution mapping and measurement of ambient concentration of sulfur dioxide and nitrogen dioxide with passive sampler

BACKGROUND: Measurements of nitrogen and sulfur dioxide using passive sampler over 12 months in Samsun, Turkey, are compared with SO(2) and NO(2) 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(2) and SO(2) averages of passive sampler was 29.65 μg/m(3) and 21.01 μg/m(3) for exposures of 2-weeks at an industrial site. The maximum monthly concentration for SO(2) was observed at the 10(th) measurement station with 44.19 μg/m(3) for August. The maximum monthly concentration for NO(2) was observed on the 3(rd) measurement station with 42.83 μg/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.
