1. Exposure and body burden of environmental pollution and risk of cancer in a historically contaminated areas
Sammanfattning : There are many villages where environmental contamination is substantial due to historical industrial activities. According to the European Environment Agency, there are about 2.5 million potentially contaminated sites in the European member states. In Sweden, there are about 80 000 more or less contaminated areas. LÄS MER
2. Landslide of contaminated soil into rivers: Environmental impacts and risks
Sammanfattning : Landslide risk assessments and environmental risk assessments are routinely carried out in many countries exposed to landslide hazards and/or contaminated soil hazards, but separately from each other. By combining results from different types of risk assessments and superimposing the results, possible multi-hazards may be revealed, which is not the case when the results are only displayed independently.

3. Fate and transport of POPs in the aquatic environment : with focus on contaminated sediments
Sammanfattning : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bioavailability and environmental transport of the POPs. LÄS MER
4. In situ remediation of contaminated sediments using thin-layer capping : efficiency in contaminant retention and ecological implications
Sammanfattning : Hydrophobic organic contaminants (HOCs) often reside in sediments sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

5. A geophysical study of an arsenic contaminated area in the Ron Phibun District, Southern Thailand
Sammanfattning : Geophysical surveys has been carried out in an arsenic contaminated area, the Ron Phibun District, southern Thailand, where tin and associated minerals, like arsenopyrite and pyrite, have been extracted from granites. The geophysical methods used are resistivity measurements, seismic refraction, GPR, self-potential, and magnetic susceptibility. LÄS MER
