Eutrophication and Contaminants in Aquatic Ecosystems
Eutrophication and persistent pollutants are two of the main environmental problems in European marine and freshwater ecosystems. As they tend to co-occur, interactive processes between eutrophication and contaminants are suggested, that may lead to environmental effects that cannot be predicted from each process alone. In order to predict the consequences of remedial measures (changing the input of organic matter, nutrients and contaminants) it …
PCB and DDT in Laminated Sediments from Offshore and Archipelago Areas of the NW Baltic Sea
Temporal trend studies of PCBs and DDTs in two annually laminated sediment cores from the offshore NW Baltic proper and the Stockholm archipelago demonstrate that studies of laminated sediments are useful tools for detecting time trends of HOCs. The concentration trends of PCBs and DDTs, on a dry weight basis, from the two cores show quite large similarities to trends reported in pelagic biota from the NW Baltic proper, although the reduction in …

PCB Levels in Laminated Coastal Sediments of the Baltic Sea along Gradients of Eutrophication Revealed by Stable Isotopes (δ 15 N, δ 13 C)
A systematic investigation of PCB in coastal sediments of the Baltic Sea was initiated in 1996 by retrieving dated subsurface layers (1992–1994) from 88 sites in 19 sheltered archipelago areas, where laminated sediments were found to be common. PCBs7 (HELCOM's standard sum of 7 congeners, ≈1/6 of total PCB) was quantified, as well as the abundance and isotopic composition of nutrients (N, C), in order to trace effects of eutrophication and potent…
Sediment Burial of PCBs in the Offshore Baltic Sea
In 1993, a large-scale investigation of polychlorinated biphenyls (PCBs) in Baltic Sea sediments was performed in cooperation between the Baltic states. sPCB (IUPAC # 52, 101, 118, 105, 153, 138, 180) in surficial sediments increased from north (mean 213 ng g−1 C) to south (mean 382 ng g−1 C), indicating atmospheric influence. In contrast to decreasing PCB trends in pelagic biota, the sPCB in dated sediment cores from the Baltic proper showed inc…
Storm Influence on the Accumulation and Lamination of Sediments in Deep Areas of the Northwestern Baltic Proper
The expanding occurrence of laminated surficial sediments in the Baltic proper has increased the possibilities to assess inter-annual variation in sediment accumulation over the past four decades. During the same period of time, wind speeds and wind directions in the area have been recorded continuously on Gotska Sandön. When studying the fine structure in three distinctly laminated sediment cores, selected from 55 cores collected within a 39 km2…

Inca Agroforestry
Historical accounts of the Inca indicate that they greatly valued trees and practiced planting to fulfil their needs for fuel and timber. These records are evaluated in the light of palaeoecological and archaeological evidence suggesting a dramatic increase in arboreal taxa from c. AD 1100 during a period of significant global temperature increase. This natural vegetation response to improving environmental conditions may have stimulated manageme…

Comparison of Temporal Trends (1940s–1990s) of DDT and PCB in Baltic Sediment and Biota in Relation to Eutrophication
Comparative temporal trend studies of ΣDDT and PCB on the Baltic pollution, using matrices from Baltic biota and dated lamina from sediment cores in anoxic sediment areas of the Baltic (no bioturbation) have been carried out. Chemical analyses of consecutive laminas of the cores representing individual years were compared to long-term temporal trend monitoring of Baltic biota based on annual sampling and analyses. Earlier studies of sediment core…
