11. Structural and physicochemical studies on metal and porphyrin binding by the Bacillus subtilis ferrochelatase
Sammanfattning : The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. LÄS MER
12. Modification of microcapsules for controlled release
Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER
13. Bioaccessibility, corrosion and surface properties of metals, alloys and metallic powder in biological fluids of relevance for occupational and consumer health hazard assessment
Sammanfattning : When assessing hazards of metals, alloys, and metal-containing items, the metal release (bioaccessibility) is of high importance. Triggered by increasingly stricter hazard classifications for metals, especially cobalt (Co), and limited knowledge, the aim of this doctoral thesis is to assess correlations between the metal/alloy surface characteristics, corrosion and metal release pattern in different simulated biological fluids relevant to human exposure scenarios (dermal, ingestion and inhalation, Papers I-V).

14. Metal accumulation by plants : evaluation of the use of plants in stormwater treatment
Sammanfattning : Metal contaminated stormwater, i.e. surface runoff in urban areas, can be treated in percolation systems, ponds, or wetlands to prevent the release of metals into receiving waters. Plants in such systems can, for example, attenuate water flow, bind sediment, and directly accumulate metals. LÄS MER
