1. The Pollution Status of Surface Sediments along the Turkish Coast of the Black Sea Mürşide Sur, Halil. I. Sur, Reşat Apak, Erol Erçağ 1

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

3. 3 Antropogenic : can be result of (directly & runoff) Mining IndustrialDomestic Agricultural * Metal form (org,inor, dis,part.) *Presence of other substances *Water system (T,S,DO, pH,current,etc) *Biological system (age,size,activity etc) Natural: Weathering of rocks and soil Atm * Dissolution, *Sorption onto org. inorg particles * Precipitation * Transportation * Products of weathering and erosion *Biogenic particles produced *Chemical precipitates Sources of sediment &pollutants River Sea Water Sediment
