Abstract
Introduction
The focus of this study is to evaluate the formation of non-extractable
residues (NER) in soil after application of 14C- test compounds and to
assess whether NER are toxic. Residual activity is found to remain in
the soil after a ‘total’ extraction, which can be present as:
• The chemical itself associated with mineral and/or organic matter
fractions;
• Transformation product;
• Microbial biomass;
• Carbonates.
At the moment NER is considered either as a potential long-term
problem or as a sustainable detoxification.
The goal of this study is:
• Develop an “extraction test” to assess the ecotoxicity of fractions
representing different degrees of bioavailability of the chemical;
• Provide a clear, mechanistically driven, definition of NER and to
confirm a lack of residual toxicity caused by NER.
