SPATIAL DISTRIBITIONS OF ORGANIC AND INORGANIC POLLUTANTS AT AN INDUSTRIAL CITY ON THE NORTHWESTERN TURKEY Mihriban Civan, Semra Tuncel and Gurdal Tuncel April 2007

OUTLINE INTRODUCTION DATA PRODUCTION PRELIMINARY RESULTS

INTRODUCTION to investigate spatial distributions of VOC, and other conventional air pollutants Consist of: Summer season sampling Winter season sampling

Sample Preparation and Handling… con’t Commercially available passive inorganic tubes for SO2, NO2 and O3 Exposure time: 1 weeks or 2 weeks Gradko Ltd.

Sample Preparation and Handling… con’t Passive Tubes

Study area Bursa Bursa Bursa 6

Study area Residential Areas Roads and Junctions Industries Background Sampling Locations include: Residential Areas Roads and Junctions Industries Background

Comparison of 1st and 2nd Sampling Period

Comparison of the Sampling Site  

Benzene Concentration (ppb) Distribution for Winter Sampling Period Pollutant Distribution Map Benzene Concentration (ppb) Distribution for Winter Sampling Period

Benzene Concentration (ppb) Distribution for Summer Sampling Period

Toluene Concentration (ppb) Distribution for Winter Sampling Period

Toluene Concentration (ppb) Distribution for Summer Sampling Period

NO2 Concentration (ug/m3) Distribution for Winter Sampling Period

NO2 Concentration (ug/m3) Distribution for Summer Sampling Period

Future Works…. Sources giving rise to observed distributions will be determined by multivariate statistics and investigation of ratios Distribution health risk associated with VOCs will be determined Complete QA/QC procedure
