Brominated compounds in Arctis
In this project area, I have studied the exchange of brominated compounds
between Sea and air. Particularly the exchange of naturally formed
bromoanisoles have been investigated and compared with antropogenic
halogenated hydrocarbons, e.g., bominated flame retardants and chlorinated
pesticides.

Drug

Assessment of drug exposure among medical staff
during preparation and administration. Last project was a screening
investigation of spill
and leakage of antibiotics during compounding and administration in
hospitals. This project was supported by AFA and was finished in
2011.

Critical work task for drug leakage

Development of measurement
methods for metals and organometals.
Many metals occur in various forms with different
toxicity.
It is therefore essential to be able to selectively determine different
forms of a metal for adequate assessment of its hazardous health effects.
In this Ph D student project, different methods for speciation of metals
were developed, e.g., speciation of hexavalent chromium in concrete and
tanned leather, transferrin bound cobalt in blood, cisplatin in plasma.

Laser
treatment.
This
project, which ended 1999, involved investigation of
aerosol exposure during metal surface treatment with high power lasers.
A possible continuation of this project is the development of methods for
emission and exposure measurements during laser treatment of composite
materials. The work has carried out in collaboration with Laser
group at Luleå Technical University, ArgeLas
in Wienna and Laser Zentrum
Hannover.
