    Sammanfattning : Anaemia is a serious public health problem in nearly all developing countries. It has negative consequences on cognitive and physical development of children, reduces work capacity in adults, and increases the risk of maternal and child mortality. LÄS MER

  3. 22. Formation, uptake and bioaccumulation of methylmercury in coastal seas : a baltic sea case study

    Författare :Aleksandra Skrobonja; Erik Björn; Agneta Andersson; Anne L. Soerensen; Marc Amyot; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mercury; methylmercury; bioaccumulation; mesososm; isotope tracers; methylation; demethylation; stability constant; kinetic model; coastal sea; ICPMS; LC-MS MS;

    Sammanfattning : Methylmercury (MeHg) is a potent neurotoxin which can bioaccumulate to harmful levels in aquatic food webs. Methylmercury formation is a predominantly biotic process which involves phylogenically diverse microorganisms (e.g. iron- or sulfate-reducing bacteria). LÄS MER

  4. 23. Understanding the causes of spatial variation in pesticide sorption and degradation at the catchment scale

    Författare :Abdul Ghafoor; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Intensive agricultural practices and use of pesticides, essential to achieve high crop yields, present particular risks to soil and water resources which sustain life. Degradation and sorption of pesticides in soils are both spatially variable and also among the most sensitive factors determining losses to surface water and groundwater. LÄS MER

  5. 24. Properties of humic substances from groundwater and surface waters

    Författare :Catharina Pettersson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Humic substances play an important role in the environment. The aim of this thesis is to enhance the understanding of the behaviour of humic substances in natural waters and their importance for mobilizatiou/immobilization, redistribution, bioavailability and removal of metals and organic pollutants from aqueous systems.

  7. 25. Nutrient dynamics in the North Pacific subtropical gyre : phosphorus fluxes in the upper oligotrophic ocean

    Författare :Karin Björkman; Tom Berman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology;

    Sammanfattning : In the contemporary North Pacific subtropical gyre (NPSG) the extant microbial community is based on prokaryotic cells with the cyanobacterium Prochlorococcus dominating the phototrophic component. The prevalence of dinitrogen (N2) fixing organisms, such as Trichodesmium spp. LÄS MER
