2. Mineral element contents in drinking water - aspects on quality and potential links to human health
Sammanfattning : Mineral elements in drinking water have been in focus for more than a decade, especially as the habit of drinking bottled water has increased, not the least among young people. Minerals in drinking water have become more important since minerals in food, especially in vegetables, have decreased substantially the last decades. LÄS MER
3. Polybrominated dibenzo-p-dioxins and furans : from source of emission to human exposure
Sammanfattning : Brominated flame retardants (BFRs), which are ubiquitous in modern life and the environment, are the major source for polybrominated dibenzo-p-dioxins and furans (PBDD/Fs). The knowledge about PBDD/Fs is lim-ited compared to other environmental pollutants, even though PBDD/Fs show similar toxicity as polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) which are considered to be among the most toxic man-made substances.

4. Elevers föreställningar om kroppens organ och kroppens hälsa utifrån ett skolsammanhang
Sammanfattning : Denna avhandling har fokus på 88 elevers föreställningar om vad som händer i kroppen då de äter en smörgås, dricker vatten och sväljer en värktablett. Sedan har jag studerat hur dessa föreställningar påverkar deras kunskaper vad det gäller kroppens fysiologi och deras ställningstagande i hälsofrågor. LÄS MER
5. Fate of riverine iron over estuarine salinity gradients
Sammanfattning : Rivers have traditionally not been considered important sources of bioavailable iron (Fe) to the marine waters, since most Fe is lost by salinity-induced aggregation and sedimentation during estuarine mixing. However, recent studies from boreal rivers found a remarkably high Fe stability, probably due to the interaction with organic matter. LÄS MER
