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

   Author : Delilah Lithner; Göteborgs universitet; []
   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

4. 2. Environmental Assessment Tools for Neighbourhoods and Buildings in relation to Environment, Architecture, and Architects

   Author : Marita Wallhagen; Göran Finnveden; Tove Malmqvist; Ola Eriksson; Josefin Wangel; Koen Steemers; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architects; architecture; buildings; environment; environmental assessment tools; environmental sustainability; neighbourhoods; Planering och beslutsanalys; Planning and Decision Analysis;

   Abstract : This thesis explores Neighbourhood and Building Environmental Assessment Tools’ (NBEATs’) function as assessment tools and decision support, and their relation to environment, architecture and architects. This is done by analysing, testing, and discussing a number of NBEATs (LEED-NC, Code for Sustainable Homes, EcoEffect, LEED-ND, BREEAM-C, and ENSLIC-tool), their manuals and use. READ MORE

5. 3. From source to the environment : Strategies for identification and determination of hydroxylated polycyclic aromatic hydrocarbons in complex particulate matrices

   Author : Rozanna Avagyan; Roger Westerholm; Conny Östman; Marja-Liisa Riekkola; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; OH-PAHs; hydroxy-PAHs; particulate matter; PM; airborne particles; combustion particles; wood combustion; suspect screening; non-target screening; high resolution mass spectrometry; HRMS; atmospheric pressure photoionization; APPI; Analytical Chemistry; analytisk kemi;

   Abstract : Adverse health effects have been linked to exposure to particulate matter, and wood combustion is considered as an important source of harmful particulate matter in the urban air and environment. Hydroxylated polycyclic aromatic hydrocarbons are a group of compounds with toxic, endocrine disrupting and carcinogenic properties. READ MORE

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

   Author : Åse Togerö; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

7. 5. Life Cycle Assessment of Paper Based Printed Circuits

   Author : Qiansu Wan; Li-Rong Zheng; Changqing Liu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Printed Electronics; Environment; PCB; Life Cycle assessment; Emissions; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability.
