  2. 1. Chemical emissions from building structures : emission sources and their impact on indoor air

    Author : Annika Glader; Ingrid Liljelind; Berndt Stenberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; VOC; building structures; emissions; health effects; moisture damage; PCA; OPLS; inomhusluft; VOC; konstruktioner; emissioner; hälsoeffekter; byggnadsmaterial; fuktskada; PCA; OPLS; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. READ MORE

  4. 2. Non-Exhaust PM10 and Road Dust

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road Dust; Abrasion Wear; Road Surface Macro Texture; Mean Profile Depth; Mean Texture Depth; Emissions; Abrasion Wear Model; NORTRIP; PM10; Air Quality; Particles; Vägdamm; Vägslitage; Dubbslitage; Textur; Emissioner; Slitagemodell; NORTRIP; PM10; Partiklar; Luftkvalitet; Byggvetenskap; Civil and Architectural Engineering; 15 Road: Environment;

    Abstract : Non-exhaust PM10 is an issue in the urban environment linked to health issues. Emissions of non-exhaust PM10 is relatable to pavement properties. Also of importance is resuspension of road dust stored from surfaces. This depends on the traffic and metrological conditions. READ MORE

  5. 3. Chemical emissions from concrete

    Author : Kristina Hjellström; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; miljöpåverkan; mätmetoder; emissioner; flyktiga organiska föroreningar; betong; VOC; emissionsmätningar;

    Abstract : The major part of this work deals with a new method for quantification of VOCs in concrete. There is a need for this type of quantification due to the development in cement and concrete production using plasticizing agents and fillers for improved rheological properties, and alternative fuels and waste materials to reduce the environmental impact of cement production.

    Abstract : Luftburna partiklar (PM) är ett problem för människans hälsa, där flertalet samband mellan negativa hälsoeffekter finns mellan luftföroreningar finns, bland annat för respiratoriska sjukdomar, lungcancer och kardiovaskulära sjukdomar med flera. I länder där dubbdäck används, till exempel Sverige, Finland och Norge, och sandning av vägar och gator genomförs vintertid för att säkerställa god friktion kommer en betydande andel av partiklarna från vägslitage och nedkrossning av sand vilket bidrar till PM10.

  7. 5. Combined solar and pellet heating systems for single-family houses : How to achieve decreased electricity usage, increased system efficiency and increased solar gains

    Author : Tomas Persson; Per Lundqvist; Simon Furbo; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin; Thermal energy engineering;

    Abstract : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. READ MORE
