4-2_2. distribution of pa hs in the environment, marija okuka

  1. 1. Distribution of PAHs in the environmentDepartment of Environmental Engineering and Occupational Safety Faculty of Technical Sciences University of Novi Sad M. S. Okuka, N. V. Šenk May 2012. Sofia
  2. 2. PAHs-Polycyclic Aromatic Hydrocarbons• Organic pollutants• Origin• Toxicity
  3. 3. PAHs-Polycyclic Aromatic Hydrocarbons• Sorption processes• Dry and wet deposition• Air/ Soil /Water
  4. 4. Structure
  5. 5. SPARC (Sparc Performs Automated Reasoning in Chemistry)Using the molecular structure model gas/particle partitioningcoefficient (Kp) is calculated using the formula: Kp f wiom K wiom K wiom - sorption coefficient calculated with SPARC softvare (ciWIOM/ciair) f wiom - mass fraction of water insoluble organic matter (wiom) in aerosol (recomended value 40%)
  6. 6. SPARC (Sparc Performs Automated Reasoning in Chemistry)The model was validated for three types of WIOM polymers Secondary organic aerosol polymers used in calculations as organic matter surrogate
  7. 7. Locations in Novi SadN1-NIS refinery,N2-Sangaj kindergarden,N3-Citys Assembly
  8. 8. Comparison of log Kp values-measured and modelled 6 5.5 B(a)P B(b)F B(k)F B(b)F 5 B(k)F B(ghi)P B(b)F B(a)P B(k)F N1 N2 4.5 N3 Line 1:1 4 B(a)A B(a)A Chr B(a)A 3.5 Chr 3 3 3.5 4 4.5 5 5.5 6
  9. 9. ConclusionPredictions for PAHs with carcinogenic, mutagenic andteratogenic properties are close to linear relationship, whichmeans that SPARC model can be used for prediction ofpartitioning and distribution processes.
  10. 10. The study of partition processesheterogenic system • air/water • air/soil • water/soilare in progress.
