1. 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
2. Towards Dense Air Quality Monitoring : Time-Dependent Statistical Gas Distribution Modelling and Sensor Planning
Sammanfattning : This thesis addresses the problem of gas distribution modelling for gas monitoring and gas detection. The presented research is particularly focused on the methods that are suitable for uncontrolled environments. LÄS MER
3. Some Factors Influencing Thermal Comfort and Air Quality in Residential Buildings. Field Measurements and Laboratory Tests
Sammanfattning : The main prerequisite for applying a specific ventilation system in residential buildings is that the demands set upon the indoor air quality and thermal climate can be satisfied. If this cannot be guaranteed using a simple exhaust system, a system with treated supply air, i.e. balanced ventilation, should be considered. LÄS MER
4. Semipermeable membrane devices as integrative tools for monitoring nonpolar aromatic compounds in air
Sammanfattning : Air pollutants pose a high risk for humans, and the environment, and this pollution is one of the major environmental problems facing modern society. Active air sampling is the technique that has been traditionally used to monitor nonpolar aromatic air pollutants. LÄS MER
5. Biological and air monitoring of exposure to isocyanates
Sammanfattning : Exposure to isocyanates may induce disorders in the airways of workers. Therefore, application, development and validation of methods for exposure assessment is of great importance. LÄS MER
