   Sammanfattning : AbstractAs air contaminants continue to pose a problem in organizations, more studies are needed to identify and reduce employees’ exposure to air contaminants. Limited research proposes methods for managing air contaminants, especially with focus on reducing exposure by improving safety behavior, safety knowledge, safety attitudes and safety motivation among employees in the workplace, by, for instance, using safety training.

3. 7. Exposure to air pollution during pregnancy and health risks for mother and child

   Författare :Ebba Malmqvist; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; pregnancy; birth outcomes; ozone modeeling; preeclampsia; Type1 Diabetes;

   Sammanfattning : We had in the present thesis the unique possibility to use, in a socio-economically relatively homogenous population, high quality registry information on a population-based birth cohort (84 039 births during the period 1999-2005) in Scania (Skåne), the most Southern county of Sweden. The aim of the thesis was to investigate whether exposure to air pollution, in an area of low-levels exposures, during different periods of the pregnancy was associated with birth outcomes, pregnancy complications and risk of the child to develop type I diabetes (T1D).

4. 8. Remote Sensing of Forest Decline in the Czech Republic

   Författare :Jonas Ardö; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Czech Republic; neural networks; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

   Sammanfattning : This thesis describes the localisation and quantification of deforestation and forest damage in Norway spruce forests in northern Czech Republic using Landsat data. Severe defoliation increases the spectral reflectance in all wavelength bands, especially in the mid infrared region. LÄS MER

5. 9. Energy Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

   Författare :Jürgen Salay; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; implementation; sustainable energy; renewable energy; electricity production; power industry; Baltic states; Poland; transition; sulphur dioxide; air pollution; energy efficiency; Energy; energy use; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Energy research; Energiforskning;

   Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

7. 10. Bark lesions and sensitivity to frost in beech and Norway spruce

   Författare :Anna Maria Jönsson; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Picea abies; Multiple stress; Mineral nutrient balance; Liming; Lichen indices; Fagus sylvatica; Cryptococcus fagisuga; Excess nitrogen; Vitality fertilization; Plant ecology; Växtekologi;

   Sammanfattning : Strong temperature fluctuations and pathogen attacks can cause bark lesions, visible signs of wounds in the phloem and cambium. Pathogenic insects and fungi are able to invade lesions that have not healed, further increasing the damage. LÄS MER
