Submarine Groundwater Discharge as a Source of Mercury in the Bay of Puck, the Southern Baltic Sea
Both groundwater flow and mercury concentrations in pore water and seawater were quantified in the groundwater seeping site of the Bay of Puck, southern Baltic Sea. Total dissolved mercury (HgTD) in pore water ranged from 0.51 to 4.90 ng l-1. Seawater samples were characterized by elevated HgTD concentrations, ranging from 4.41 to 6.37 ng l-1, while HgTD concentrations in groundwater samples ra...
متن کاملReview of Heavy Metal Accumulation in Aquatic Environment of Northern East Mediterrenean Sea Part II: Some Non-Essential Metals
Heavy metals that enter marine environment and remain in the water as well as the sediments are accumulated by aquatic organisms, thus becoming highly good indicators to monitor metal accumulation in the long run. Metals are potentially harmful to humans and most organisms at varied levels of exposure and absorption. Northern East Mediterranean Sea is a crucial region as it is an area, shared b...

متن کاملComposition and Transformation of Dissolved Organic Matter in the Baltic Sea
The processing of terrestrial dissolved organic matter (DOM) in coastal shelf seas is an important part of the global carbon cycle, yet, it is still not well understood. One of the largest brackish shelf seas, the Baltic Sea in northern Europe, is characterized by high freshwater input from sub-arctic rivers and limited water exchange with the Atlantic Ocean via the North Sea. We studied the mo...
متن کاملAssessment of sediment quality in Baltic Sea coastal waters
The investigations on the quality status of the sediments in the German Baltic Sea coastal waters focused on the natural background as assessment basis. On this basis, the chemical sediment quality can be evaluated. Furthermore, the decision about the relocation of dredged material from federal waterways depends on this assessment. The sediment quality of the German Baltic Sea coastal waters be...
