1. 1. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

   Författare :Benoit Guieysse; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

   Sammanfattning : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. LÄS MER

3. 2. Ionization and Fragmentation of Complex Molecules and Clusters : Biomolecules and Polycyclic Aromatic Hydrocarbons

   Författare :Henrik A. B. Johansson; Henning Schmidt; Henrik Cederquist; Henning Zettergren; Thomas Schlathölter; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

   Sammanfattning : This work deals with ionization and fragmentation of biomolecules and polycyclic aromatic hydrocarbon (PAH) molecules. They are studied in the gas phase both as isolated molecules and as weakly bound clusters. LÄS MER

5. 4. Biodegradation of hydrocarbons in soil and water

   Författare :Mikael Eriksson; KTH; []
   Nyckelord :Solid Phase Microextraction; SPME; biodegradation; bioremediation; bioavailability; monitoring; Volatile Organic Compounds VOC ; Screening; headspace sampling; polycyclic aromatic hydrocarbons; PAHs; aliphatic hydrocarbons; total petroleum hydrocarb;

   Sammanfattning : Biodegradation of aliphatic and polycyclic aromatichydrocarbons was studied in soil and liquid cultures attemperatures ranging from -5 º C to 20 º C undervarious aerobic or anaerobic, nitrate reducing, conditions. Twocontaminated soils were used in the studies. LÄS MER

7. 5. Determination of Volatile Hydrocarbons in Urban Air

   Författare :Lars Löfgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; arenes; hydrocarbons; environment; alkenes; motor traffic; photochemical oxidant formation;

   Sammanfattning : In the complex hydrocarbon mixture in urban air, the alkenes and arenes are of particular interest with respect to impact on health and environment. Knowledge of hydrocarbon concentrations in urban air is essential for the assessment and prevention of health hazards and photochemical oxidant formation. LÄS MER
