  2. 21. Soil compaction: effects on soil hydraulic properties and preferential water flow

    Author : Mona Mossadeghi Björklund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Soil compaction caused by passage of agricultural machinery over the surface is an issue in many agricultural soils with a high clay content. Compaction is known to modify soil pore structure and soil hydraulic properties, but can also affect the occurrence of preferential flow. READ MORE

  4. 22. Insect pollination of oilseed rape

    Author : Sandra Lindström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. READ MORE

  5. 23. Environmental fate of chemicals released from consumer products : Multimedia modelling strategies

    Author : Anna Palm Cousins; Michael McLachlan; Antonio Di Guardo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multimedia fate model; urban model; PBDEs; phthalate esters; indoor environment; emissions; exposure; BDE 209; DINP; DEHP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The objective of this thesis was to assess the environmental fate and transport of chemicals emitted from consumer products through the development and application of modelling tools. The following hypotheses were tested: i) Multimedia fate models can be applied in a multistage assessment process to emerging chemicals when limited knowledge exists to identify the likely environmental fate and to direct further research; ii) the indoor environment acts as a source of anthropogenic substances in consumer products to the outdoor environment; and iii) chemical removal pathways in the indoor environment are important for the fate of organic chemicals in densely populated areas.

  6. 24. Hazard Identification of Anti-fouling Paints and Contaminated Sediments by the Use of Biological Tests in Brackish Water

    Author : Jenny Karlsson; Britta Eklund; Magnus Breitholtz; Göran Dave; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti-fouling paints; Toxicity tests; Hazard identification; Sediment toxicity; Ceramium tenuicorne; Nitocra spinipes; Environmental engineering; Miljöteknik; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Ecotoxicological test methods are important tools in environmental risk assessment to investigate possible adverse effects that chemical substances may cause to aquatic ecosystems. The main aim of this doctoral thesis was to identify potential toxicity (hazard) of anti-fouling compounds and paints as well as contaminated sediments. READ MORE

  7. 25. Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change

    Author : Juan Camilo Acosta Navarro; Ilona Riipinen; Annica M.L. Ekman; Hans-Christen Hansson; Risto Makkonen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; Air quality; Land use; General circulation; Atmosphere-Ocean interactions; Aerosol climate effects; Earth system modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. READ MORE
