A new and easy fast-screening test (the Ad-DR bioassay) for dioxins in biological samples from highly dioxin-contaminated areas was developed. The aryl-hydrocarbon-receptor (AhR) reporter system was utilized to transport dioxin-responsive-element (DRE) via an adenovirus vector into a rat ...

In the Noorderkempen (NW Belgium), a large area (about 280 km²)is contaminated with cadmium (Cd) and zinc (Zn) due to a historical pollution by the Zn smelters. Direct aquatic emissions of metals have strongly reduced from historic ones, however surface water metal concentration largely ...
