  1. 1. Road traffic metals sources and emissions

    University dissertation from Kalmar

    Author : David Hjortenkrans; Högskolan i Kalmar.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission patterns; Heavy metals; Roadside soil; Sweden; Traffic; Sequential extractions; SFA; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Miljökemi; Environmental Chemistry;

    Abstract : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. READ MORE

  2. 2. The trace of metals : Use, emissions and sediment load of urban heavy metals

    University dissertation from Linköping : Linköpings universitet

    Author : Arne Jonsson; Linköpings universitet.; Linköpings universitet.; [2000]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Urban areas have been considered potential ecological hot spots for metal pollution. This is the result of three trends. First, the 20th century saw a rapid increase in the use of many materials, including metals, in the industrialized world. Second, urbanization has made towns and cities areas nodes of material flows.

  3. 3. Alkali Metal Adsorption on Metals Studied by Hiqh Resolution Core Level Spectroscopy and Low Energy Electron Diffraction

    University dissertation from Synchrotron Radiation Research

    Author : Edvin Lundgren; Lund University.; Lunds universitet.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low Energy Electron Diffraction; Physics; Core Level Spectroscopy; Surface Structures Photoelectron Emission; Single Crystal Surfaces; Alkali Adsorption; Aluminium; Metals; Alkali Metals; Fysik; LEED.; Fysicumarkivet A:1996:Lundgren;

    Abstract : Alkali metal adsorption on metals is studied by High Resolution Core Level Spectroscopy (HRCLS) and Low Energy Electron Diffraction (LEED). The studies can be divided into two parts: adsorption of alkali multilayers and alkali adsorption in the submonolayer regime. READ MORE

  4. 4. Urban heavy metals : Stocks and flows

    University dissertation from Linköping : Linköping University

    Author : Louise Sörme; Linköpings universitet.; Linköpings universitet.; [2003]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Heavy metais; urban areas; Substance flow analysis; inflow; stock; outflow; diffuse emisson; waste; wastewater treatment plant; legislation; Tungmetaller; miljöaspekter; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Levels of heavy metals in different media are high today, both in Stockholm and other urban areas. Where do the metals come from? Production emissions and point sources are not the answer, since earlier research has shown that production emissions are lower than emission from goods during use (the diffuse emission). READ MORE

  5. 5. Antibiotic Resistance Selection in the Presence of Metals and Antimicrobials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa M. Albrecht; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; Metals; Antimicrobials; Bacterial evolution; Bacterial genetics; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : The external environment is complex: Antibiotics, metals and antimicrobials do not exist in isolation but in mixtures. Human activities such as animal husbandry, fertilization of agricultural fields and human medicine release high amounts these compounds into the environment. READ MORE
