  1. 1. Environmental and health hazards of chemicals in plastic polymers and products

    Author : Delilah Lithner; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : plastics; plastic products; plastic polymers; consumer products; environmental hazards; environment; health hazards; human health; hazard ranking; hazard assessment; chemical ranking; hazard identification; hazard classifications; hazardous chemicals; hazardous substances; toxic substances; monomers; polymers; toxicity; acute toxicity; toxicity tests; Daphnia magna; Toxicity Identification Evaluation; TIE; leaching; leachates; product leachates; leaching tests; plastic materials; plastic;

    Abstract : Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has doubled, reaching 245 million tons in 2008. READ MORE

  2. 2. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics

    Author : Peter Mellbo; Tommy Claesson; Sirkku Sarenbo; Hans Samuelsson; Högskolan i Kalmar; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ash products; Wood ash; Leaching; Drying; Nutrient; ; Sustainable forestry; Forestry; Skogsskötsel; Miljövetenskap; Environmental Science;

    Abstract : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. READ MORE

  3. 3. When the Rubber Meets the Road -Ecotoxicological Hazard and Risk Assessment of Tire Wear Particles

    Author : Anna Wik; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : tire wear; tire particles; rubber; leaching tests; ecotoxicity tests; Daphnia magna; Ceriodaphnia dubia; Pseudokirchneriella subcapitata; Danio rerio; toxicity identification evaluation; detention ponds; hazard assessment; risk assessment;

    Abstract : Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this th.. READ MORE

  4. 4. Leaching of Hazardous Substances from Concrete Constituents and Painted Wood Panels

    Author : Åse Togerö; Chalmers University of Technology; []
    Keywords : thiocyanate; biocides; leaching; runoff; admixture; coatings; resin acids; blast furnace slag; toxic; fly ash; cement; tall oil; diffusion paints; concrete;

    Abstract : At a time of increased concern about environmental issues in the building sector, it is essential to know the environmental performance of different building materials. Knowledge of the possible release of hazardous substances in building materials is scarce, and these aspects have often been neglected in environmental assessment methods. READ MORE

  5. 5. Recycling Inorganic Residues from Wood-based Industries to the Forest- study of Treatment Techniques and Leaching Characteristics

    Author : Maryam Mahmoudkhani; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Treatment techniques; Alkaline solid residues; Heterogeneous reactions; Modified column-pHstat test; Recycling; Leaching; Characterization; Field test;

    Abstract : Abstract. In order to minimize the negative impact of loss of nutrients in the forest soil (when harvesting the wood), inorganic solid residues, from wood-based industries, have to be recycled back to the forest soil. READ MORE
