6. Lake sediments around the Antarctic Peninsula : archives of climatic and environmental changes
Sammanfattning : Lakes and lake sediments from four areas around the Antarctic Peninsula are described.The concentrations of trace metals in sediment are found to be a useful tool in distinguishing between the different sedimentary phases during a transition from marine to limnic environment.

7. Local and global contaminants in Swedish waters : studies on PCBs, DDTs, 4,5,6-trichloroguaiacol and their transformation products in fish and sediments
Sammanfattning : This thesis is focused on studies on the environmental fate and methodological improvements for determination of the global contaminants, PCBs and DDTs, and locally discharged phenolics, e.g. 4,5,6-trichloroguaiacol (4,5,6-TCG), and their transformation products. LÄS MER
8. A Deep Dive into Sediments : Exploring approaches to assess environmental risks and achieving environmental goals in management of contaminated sediments in Sweden
Sammanfattning : Contaminated sediments are common, especially near urban and industrialized areas, and they can have negative ecological effects. In three studies, I explore the challenges for environmental management of contaminated sediments, focusing on environmental risk assessment (ERA) in Sweden. LÄS MER
9. Spatial modeling in sediments
Sammanfattning : In a marine environment the sediments play an important role. They act as sinks, where the concentrations often are higher than in the water mass above, but also as sources for numerous pollutants. LÄS MER
10. Microcystis in lake sediments : its potential role in phosphorus exchange between sediment and lake water
