1. Environmental and health hazards of chemicals in plastic polymers and products
Sammanfattning : 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. LÄS MER
2. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics
Sammanfattning : 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. LÄS MER
3. When the Rubber Meets the Road -Ecotoxicological Hazard and Risk Assessment of Tire Wear Particles
Sammanfattning : 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.. LÄS MER
4. Leaching of Hazardous Substances from Concrete Constituents and Painted Wood Panels
Sammanfattning : 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. LÄS MER
5. Recycling Inorganic Residues from Wood-based Industries to the Forest- study of Treatment Techniques and Leaching Characteristics
Sammanfattning : 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. LÄS MER
