1. Metals take flight : Transport and effects across ecosystems
Sammanfattning : Metal contamination can have severe toxic effects in the ecosystems, resulting in loss of biodiversity, reduced abundance of organisms, and loss of ecosystem services. Traditionally, aquatic ecosystems have been regarded as a sink of metal contamination. LÄS MER
2. Toxic metals in pregnancy : distribution and effects on placental function in mice, and toxicity to embryonic cells in vitro : arsenic, cadmium, chromium, lead, and mercury
Sammanfattning : .... LÄS MER
3. Metals in MSWI fly ash - problems or opportunities?
Sammanfattning : Incineration of municipal solid waste is a commonly used management method to take care of our waste. However, the residues produced are a problem. They often contain large amounts of potentially toxic metal compounds and soluble salts, which can cause harm to the environment and human health if released from the ash. LÄS MER
4. Trace metals in the atmosphere : the wet deposition of trace metals : the selenium cycle
Sammanfattning : Cd, Cu, Fe, Mn, Pb and Zn concentrations in wet deposition have been monitored in Sweden since the autumn of 1983. Concentrations of these elements are highest in southern Sweden and decrease northward. Examination of enrichment factors, relative to crustal material, indicate that the major source of Cd, Cu, Pb and Zn is anthropogenic emissions. LÄS MER
5. Transcriptional biomarkers of toxicity – powerful tools or random noise? : An applied perspective from studies on bivalves
Sammanfattning : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. LÄS MER
