  1. ThePollutionStatus of SurfaceSediments alongtheTurkishCoast of the Black Sea Mürşide Sur, Halil. I. Sur, Reşat Apak, Erol Erçağ

  2. Whysedimentsareimportant? • Resources(petroleum and natural gas, minerals, etc.) • Record of past processes andconditions on theearth. • ( Rates of continental erosion and transport by rivers, Biological activity in surface watersetc.) • Aquatic life Sediment Pollution: Contaminants& loose particles from soil, rock,suspended in a body of water settle to the bottom

  3. Sources of sediment &pollutants Atm Natural: Weathering of rocks and soil • Antropogenic: can be result of (directly & runoff) • MiningIndustrialDomesticAgricultural River *Dissolution, *Sorption onto org. inorgparticles * Precipitation * Transportation *Metal form (org,inor, dis,part.) *Presence of othersubstances *Watersystem (T,S,DO, pH,current,etc) *Biologicalsystem (age,size,activityetc) Sea Water *Products of weathering and erosion*Biogenic particles produced *Chemical precipitates Sediment

  5. SamplingStations ContaminationFactor of Aluminum Kaolinite: (Al2Si2O5 (OH)4) Al ; moderately enrichment (Yomra)

  6. Sampling Stations ContaminationFactor of Cadmium Cd; considerable level enrichment (Bartın)

  7. SamplingStations ContaminationFactor of Copper Cu; Very high level enrichment (SK1)

  8. SamplingStations ContaminationFactor of Lead Pb; considerable level enrichment (SK1)

  9. SamplingStations ContaminationFactor of Mercury Hg; Very high level enrichment (Giresun)

  10. SamplingStations ContaminationFactor of Vanadium V; Very high level enrichment (Yeşilırmak R) Essential for some species, accumulate in tunicates, ascidians

  13. Ranking order of sediment contamination

  14. SUMMARY*SK1 Very high contaminated *SK2 Considerably contaminated*Şile Low degree contaminated* EBS considerable degree contaminated* WBS moderately contaminated Hg and V dominant pollutantsAl, Cd, Cu, Pb moderately or low level pollutantsTo prevent; *Erosion control (stream bank fencing , reducing impervious surfaces, creating rain garden, strip cropping etc.)*Waste water treatment – industrial -domestic, untreated Industrial , domestic waste discharges Agricultural runoff
