  2. 11. Modelling climate change impacts on pesticide leaching : uncertainty and scenario analysis at field and regional scales

    Author : Karin Anna Steffens; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Climate change projections for Sweden indicate increases in both temperature and precipitation. In a warmer and wetter climate, weed and pest pressures are likely to increase, which might in turn trigger an increased use of pesticides. READ MORE

  4. 12. Baltic Sea sediments : Source and sink for metal contamination

    Author : Sina Shahabi-Ghahfarokhi; João Marcelo Ketzer; Alessandro Amorosi; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Baltic Sea; sediments; acid sulfate soil; metal; remediation; reoxygenation; X-ray absorption spectroscopy; Environmental Chemistry; Miljökemi; Miljövetenskap; Environmental Science;

    Abstract : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. READ MORE

  5. 13. In situ measurements of radionuclide concentration in soil : An investigation into detector properties and methods

    Author : Johan Kastlander; Christoph Bargholtz; Mats Isaksson; Stockholms universitet; []
    Keywords : In situ gamma-ray spectrometry; LaBr3; CdTe; Cs-137; soil samples; fysik; Physics;

    Abstract : In case of a release of radioactive nuclides into the environment it is necessary to  have reliable methods to estimate the potential effect on people and the ecosystem. In this context the total activity deposited, the elemental composition and the depth distribution are of importance. READ MORE

  6. 14. Advances in time-domain induced polarization monitoring with application on chlorinated solvents contamination : Towards scalable real-time geophysical monitoring

    Author : Aristeidis Nivorlis; Teknisk geologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geoelectrical monitoring; Chlorinated solvents; geophysics; Electrical resistivity tomography ERT ; Contaminated soil; contamination remediation geophysics;

    Abstract : Environmental pollution is a significant concern for scientists, practitioners, authorities and the society. Among the various pollutants, chlorinated solvents pose a considerable risk to our groundwater resources. READ MORE

  7. 15. Evaluation of Modern Irrigation Techniques with Brackish Water

    Author : Tarek Selim Aboulila; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soil water; Soil Salinity; Drip irrigation; HYDRUS-2D 3D; El-Salam Canal; Egypt.;

    Abstract : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. READ MORE
