6. Diffuse emissions from goods : influences on some societal end products
Sammanfattning : End products of society (e.g. sewage sludge and incineration ashes) can be used as indicators of the use of chemicals in consumer goods. Through upstream work the sources of substances released from goods may be identified before the emissions reach the end products. LÄS MER
7. Climate change and metal mobility in an environmental risk perspective
Sammanfattning : .... LÄS MER
8. Uncertainty, variability and environmental risk analysis
Sammanfattning : The negative effects of hazardous substances and possible measures that can be taken are evaluated in the environmental risk analysis process, consisting of risk assessment, risk communication and risk management. Uncertainty due to lack of knowledge and natural variability are always present in this process. LÄS MER
9. Lake sediment as environmental archive : natural and anthropogenic influence on the chronology of trace elements
Sammanfattning : The focus of this thesis is the historical pollution of some seldom-monitored trace elements (SMTEs; Ag, Be, Ga, In, Sb and Tl) that have been involuntarily released for several thousands of years but whose usage have increased during the industrial era. Sediment cores from four rural lakes in a south to north transect in central Sweden, and two urban lakes have been used as environmental archives for chronological studies. LÄS MER
10. Road traffic metals : sources and emissions
Sammanfattning : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. LÄS MER
