2. 1. The accessibility and chemical activity of polycyclic aromatic hydrocarbons in soil

   Author : Fredrik Reichenberg; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Remediation; Bioavailability; Soil and sediment pollution; Environmental chemistry; Miljökemi;

   Abstract : This thesis proposes the use of two concepts: accessibility and chemical activity. Accessibility describes the mass quantity of PAHs that is or can become available within a given time span and under given conditions. READ MORE

4. 2. Legacy and emerging pollutants in pristine and polluted boreal catchments

   Author : Anh Minh Nguyen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Persistent organic pollutants (POPs) are bioaccumulative chemicals that are ubiquitously and globally distributed in the environment. Several species of POPs have been studied extensively and are continuously being monitored in various environmental matrices for decades. READ MORE

5. 3. The soil as a source material in archaeology. : Theoretical considerations and pragmatic applications

   Author : Johan Linderholm; Roger Engelmark; Martin Bell; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Environmental archaeology; Geoarchaeology; Prehistory; Soil phosphate; Magnetic susceptibility; Soil chemistry; Site formation processes; Soil erosion; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

   Abstract : This thesis deals with questions on various applications using soils and sediments as sources of information in archaeological research. Human environmental impact on soils and sediments, in terms of pollution, is a well known phenomenon as the industrialisation intensified during historical times and onwards and has left strong pollutive marks.

6. 4. Dynamics of forest soil chemistry

   Author : Mattias Alveteg; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; critical loads; regional; recovery; acidification; modelling; SAFE; MAKEDEP; Kemiteknik och kemisk teknologi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Abstract : Acidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.

7. 5. Baltic Sea sediments : Source and sink for metal contamination

   Author : Sina Shahabi-Ghahfarokhi; João Marcelo Ketzer; Alessandro Amorosi; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Baltic Sea; sediments; acid sulfate soil; metal; remediation; reoxygenation; X-ray absorption spectroscopy; Environmental Chemistry; Miljökemi; Miljövetenskap; Environmental Science;

   Abstract : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. READ MORE
