  2. 1. Toxicity of Inorganic Aluminium in Humic Streams

    Author : Cecilia M. Andrén; Emil Rydin; Hans Borg; Ann-Kristin Eriksson Wiklund; Björn-Olav Rosseland; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic Al; toxicity; acidification; humic streams; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Aluminium (Al) has been recognised as a main toxic factor alongside pH in acidified water ecosystems. The toxic effect of Al has been attributed to inorganic Al (Ali), though there are few in situ studies in ambient humic waters which are the focus of this thesis. READ MORE

  4. 2. Occupational hexachloroethane exposure and toxicity : With special reference to the formation of Hexachlorobenzeneiin aluminium degrassing

    Author : Anders Seldén; Sverre Langård; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : For about half a century, hexachloroethane (HCE) has been used as an essential component of military white smoke munition and as a degassing agent in almninium foundries and secondary aluminium smelters. However, the acute or chronic health risks associated with occupational exposure to HCE have not been investigated in humans. READ MORE

  5. 3. Removal of metals from contaminated waters : Evaluating the use of synthetic adsorbents and green algae biomass

    Author : Roxana Quiroga Flores; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metals; toxicity; Adsorption; uptake; arsenic; cadmium; lead; methylmercury;

    Abstract : Metal contamination of water bodies has attracted global attention owing to its environmental toxicity, abundance and persistence. Metals such as arsenic, cadmium and mercury are of greater concern since they are toxic even at low concentrations. READ MORE

  6. 4. Wild plants can improve their rhizosphere chemistry in acid soils

    Author : Marion Schöttelndreier; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; wild plants.; time pattern; soil heterogeneity; rhizotrons; rhizosphere; pH; oxalic acid; nutrient availability; malic acid; hydroponics; citric acid; 14C; biodegradation; acid soils; aluminium toxicity; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära; Plant biochemistry; Växtbiokemi;

    Abstract : Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. READ MORE

  7. 5. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation

    Author : Sulena Pradhan; Inger Odnevall Wallinder; Jonas Hedberg; Eva Blomberg; Emma Strömberg; Kerstin Forsberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; freshwater; di-hydroxybenzoic acid; humic acid; copper; aluminium; manganese; dissolution; agglomeration; stability; complexation; Kemi; Chemistry;

    Abstract : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.
