Emerging contaminants in the environment

Start date 01/01/2003
End date The project is closed: 30/08/2018

​New or emerging metallic contaminants are emitted into the environment as a result of rapid technological development and the introduction of new consumer and industrial products. Examples of new metallic contaminants include antimony (batteries, automobile brakes, tire rubber and flame retardants), silver nanoparticles (detergents) and platinum group elements (catalysts and electronics).

Our work aims at studying the emission and fate of new metallic contaminants. This work has included a number of projects with two areas of leading expertise:

  • platinum group elements (PGE) in the environment
    PGE are among the least abundant elements in the Earth’s continental crust. We have reported elevated concentrations in urban and mining environments, as well as dispersion at regional and local scales. Emitted PGE can be taken up and bioaccumulated by organisms, posing therefore a possible risk for man and the environment.
  • trace element analysis by inductively coupled plasma-mass spectrometry (ICP-MS)
    Studies on emerging contaminants rely on the availability of sensitive analytical techniques. Our work focuses on the application of ICP-MS to trace element determination. In environment matrices.

 

The project is carried out at the Division of Water Environment Technology.
