1. 1. Improved environmental monitoring and assessment : Establishing links between effects of chemical pollution at different levels of biological organization in a Baltic Sea bioindicator species (Monoporeia affinis)

   Författare :Martin Reutgard; Magnus Breitholtz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental health assessment; environmental monitoring; chemical pollution; hypoxia; bioindicators; biomarkers; teratogenicity; embryo toxicity; oxidative stress; acetylcholine esterase. Monoporeia affinis; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : A large number of chemicals enters the marine environment via atmospheric deposition, run-off, rivers and streams, industrial effluents and municipal wastewater. To understand how chemicals affect environmental health, monitoring and assessment approaches need to combine physical, chemical and biological effect parameters from different levels of biological organization.

3. 2. Nonpoint source water pollution management : Monitoring, assessment and wetland treatment

   Författare :Lorin Reinelt; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : The management of nonpoint (diffuse) sources of-water pollution has received increased attention during the past decade. New techniques that aid in the identification and assessment of these diffuse sources can increase the chances for success of nonpoint source control efforts. LÄS MER

4. 3. Source-Receptor Modeling of Air Pollution : Assessment of Source Contributions: Source Characterization and Chemometric Applications

   Författare :Emma Hedberg Larsson; Christer Johansson; H.-C. Hansson; Ralf Torgrip; Paulo Artaxo; Stockholms universitet; []
   Nyckelord :Particles; Source-receptor modeling; PMF; Elemental source profiles; Levoglucosan; Wood combustion; Air pollution; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Particles released to the atmosphere from anthropogenic sources affect the Earth’s climate as well as the health of the population. Anthropogenic sources of atmospheric particles are e.g. the combustion of biomass and fossil fuels, road, brake and tire wear and various industrial activities. LÄS MER

5. 4. Air Pollution from Ships - Emission Measurements and Impact Assessments

   Författare :Hulda Winnes; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

   Sammanfattning : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. LÄS MER

7. 5. Isocyanates - assessment of human exposure

   Författare :Håkan Tinnerberg; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Miljöteknik; kontroll av utsläpp; Analytical chemistry; Analytisk kemi; exposure; biomonitoring; occupational; isophorone diisocyanate; hexamethylene diisocyanate; methylenediphenyl diisocyanate; toluene diisocyanate; amines; aminoisocyanates; polyurethane; isocyanates; Liquid chromatography; Environmental technology; mass spectrometry;

   Sammanfattning : Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. LÄS MER
