1. The trace of metals : Use, emissions and sediment load of urban heavy metals
Abstract : Urban areas have been considered potential ecological hot spots for metal pollution. This is the result of three trends. First, the 20th century saw a rapid increase in the use of many materials, including metals, in the industrialized world. Second, urbanization has made towns and cities areas nodes of material flows.

2. Passive sampling for monitoring of inorganic pollutants in water
Abstract : As new environmental management policies for watersheds are implemented, there has been a growing interest for new monitoring alternatives. Traditionally grab sampling has been the method of choice for monitoring purposes, but may not be adequate or economically viable, to meet the requirements of the new policies. READ MORE

3. Transcriptional biomarkers of toxicity – powerful tools or random noise? : An applied perspective from studies on bivalves
Abstract : 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. READ MORE

4. A Passive Sampling System for Monitoring Metals in the Aquatic Environment
Abstract : Water monitoring is undertaken routinely as a requirement of water quality legislation. It is usual that water monitoring is undertaken through spot sampling. A passive sampling system has been developed for the aquatic environment that provides time-averaged (integrated) concentrations for metals. READ MORE

5. Fluid-rock interaction in two seismically active areas : The Tjörnes Fracture Zone, northern Iceland and the Shillong Plateau, northeastern India
Abstract : Hydrogeochemical monitoring can improve our understanding of fluid-rock interaction, and may detect anomalies that are precursory to- or caused by- earthquakes. In this study, hydrogeochemical monitoring was carried out in two distinct tectonic settings, to study coupling between hydrogeochemical changes and seismic activity. READ MORE
