1. Transport and fate of hydrophobic organic compounds in the Baltic aquatic environment : polycyclic aromatic hydrocarbons, polychlorinated dibenzodioxins and dibenzofurans
Sammanfattning : .... LÄS MER
2. Characterization of PAH-contaminated soils focusing on availability, chemical composition and biological effects
Sammanfattning : The risks associated with a soil contaminated by polycyclic aromatic hydrocarbons (PAHs) are generally assessed by measuring individual PAHs in the soil and correlating the obtained amounts to known adverse biological effects of the PAHs. The validity of such a risk estimation is dependent on the presence of additional compounds, the availability of the compounds (including the PAHs), and the methods used to correlate the measured chemical data and biological effects.

3. Methodologies to assess the fate of polar organic compounds in aquatic environments
Sammanfattning : Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements.

4. Models of the Distribution of Persistent Organic Pollutants in the Marine Environment
Sammanfattning : Persistent organic pollutants (POPs) is a group of chemicals that are toxic, undergo long-range transport and accumulate in biota. Due to their persistency the distribution and recirculation in the environment often continues for a long period of time. LÄS MER
5. Toxicological and Chemical Characterization of Organic Pollutants with Potential to Adversely Affect Fish
Sammanfattning : Several investigations have described adverse effects in fish inhabiting polluted areas, though the causative, or aetiologic compounds have not been substantiated. Since environmental pollutants exist as complex mixtures, reliable risk estimations are difficult to obtain. LÄS MER
