11. Modelling as a Tool to Evaluate Continuously Measured Concentration Value of Gaseous Indoor Air Pollutants
Sammanfattning : Results from studies of air quality in buildings are often difficult to interpret and evaluate and, in order to avoid erroneous conclusions, special evaluating tools may be needed. Modelling in various forms can be used as a method of evaluating measured values from such investigations. LÄS MER
12. Assessing environmental exposures. Air pollution in Scania, southern Sweden
Sammanfattning : Background: The environment where we humans live provides the fundamental requirements we need to survive – food to eat, water to drink, and air to breathe. The quality of these elements has a major impact on human health, as they can contain substances that are detrimental to health. These we call environmental pollutants. LÄS MER
13. Polychlorinated biphenyls (PCB) in a river ecosystem
Sammanfattning : Atmospheric deposition is one source of persistent pollutants such as polychlorinated biphenyls (PCB) in aquatic environments. Other point sources can also contribute to the PCB loadings in the water. LÄS MER
14. De-icing salt and the roadside environment : Air-borne exposure, damage to Norway spruce and system monitoring
Sammanfattning : After decades of investigation, we still have to deal withthe problem of environmental effects of the use of de-icingsalt on roads. Lacking useful indicators of the system, westill do not know the environmental utility of ameliorativemeasures taken. LÄS MER
15. Levels of brominated flame retardants in humans and their environment : occupational and home exposure
Sammanfattning : Plasma from workers at an electronic dismantling plant were analysed for tri- to heptaBDEs (brominated diphenyl ethers), during 18 months. The different exposed groups showed concentrations ranging from 0.06to 2.8 ng g-1 (l. LÄS MER
