Environmental toxicology

Main content

Illustration of environmental toxicology

Toxicology is the study of toxic compounds and how these compounds can affect living organisms. In environmental toxicology we are especially concerned with how compounds are being distributed in the environment and taken up in the food chain, thereby affecting important components of the ecosystem. At the same time knowledge about how these compounds exert their mechanisms of action in a few species provides a basis for understanding effects in related groups. In this way fish, e.g. zebrafish, can be useful model organisms for understanding mechanisms that cannot be studied in humans or polar bears.

Master thesis on the effects of bisphenol compounds on Atlantic cod estrogen receptor

Catching cod in the Oslo fjord

Several partners of the dCod 1.0 project participated in field studies in the Oslo fjord. The aim of the expedition was to study the pollution levels of cod in this popular area. For two of the four days they were joined by ecology students and teachers from the University of Oslo.

First dCod workshop

The first workshop in the dCod 1.0 project was organized at Voss during a busy December month. 22 participants from all Norwegian partners participated in discussions, cross-disciplinary crash courses, and teambuilding.

How environmental pollutants can threaten our health

Even low doses of environmental pollutants can threaten our health. The current epidemic of obesity and type 2 diabetes in western countries may be directly related to the effects of even small amounts of environmental pollutants on our bodies.
