Chromium in spruce shoots from the Saarland conurbation

Significant decrease in chromium contamination since the mid 1980s

Plants are capable of chromium uptake and accumulation. Chromium contents of one-year-old shoots of spruce therefore reflect the respective environmental contamination.

Since 1985 chromium levels in spruce from the Saarland conurbation (Saarländischer Verdichtungsraum) sampling site Warndt have decreased significantly. This is probably related to modernisations in the steel industry and the close-down of the old coke oven in the near-by Völklingen industrial region.
