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 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 toseptember 2010 are analyzed.results: the highest value for annual no2 and so2 averages of passive sampler was 29.65 ?g/m3 and 21.01 ?g/m3for exposures of 2-weeks at an industrial site. the maximum monthly concentration for so2 was observed atthe 10th measurement station with 44.19 ?g/m3 for august. the maximum monthly concentration for no2 wasobserved on the 3rd measurement station with 42.83 ?g/m3 for november. a negative correlation between nitrogendioxide concentrations and temperature (r2 = ?0.5489) was estimated. a positive correlation between nitrogendioxide measurement with passive sampler and continuous measurement (r2 = 0.6571) was estimated.
