Ecotoxicity of S3 before and at the end of the biological treatment. Collembola mortality percentages versus the amount of contaminated soil occurring in the sample when it was assayed S3 before treatment (
) and S3 resulting from the four-months treatment in the slurry-phase reactors with (
) and without (
) Enzyveba and in the parallel solid-phase reactors with (
) and without (
) Enzyveba. Each value is the result of a single measurement on samples obtained by combining equal amounts of soil of the duplicate reactors.
