alpha-HCH contamination of roe deer from the Nationalpark Harz
Decreasing contamination since the early 1990s
alpha-HCH is environmentally persistent and enriches in organisms and the food web. It is the main constituent of technical HCH which has been banned in Europe in 1991.
The effectiveness of the ban is reflected in decreasing alpha-HCH contamination of roe deer from the NP Harz.
The roe deer is the most common of the larger herbivores (first order-consumer) to be found in the wild in Europe.
