- Abstract
The article studies the influence of soil properties and aging on the toxicity of copper on compost worm and barley. Ecotoxic effect was assessed by determining growth inhibition of barley and compost worm mortality. Results indicate that copper toxicity was mainly influenced by pH and, to a lesser extent, by organic matter and clay content. Aging in organic soils revealed a slight reduction in ecotoxicity while an increase was observed in soils with low organic matter content. Further investigation using longer aging periods would be necessary to assess the significance of this observation.
