soluble fraction
Parameter corresponding to the quantity of total dissolved matter in a sample resulting from the leaching of a solid sample under well-defined operating conditions (e.g. leaching according to standard NF EN 12457-2).
leaching
Treatment of a substance or waste with a liquid to extract its soluble constituents in accordance with current standards.
percolation
Leaching of waste in a column by a counter-current fluid. The upward percolation test consists of a percolation cell, an injection pump, a circulation cell, a conductivity probe, a collection jar and a bubbler.
ecotoxicity
Identifies the toxicity of a substance to the living environment. Toxicity may be local or limited to an ecosystem. In ecotoxicology, the ecotoxicity potential is calculated at the level of ecosystem quality, then transposed and reported per kg of equivalent substance.
