Abstract:
Sewage sludge (biosolids) management represents a worldwide issue. Due to its valuable prop-
erties, approximately one half of the EU production is recovered in agriculture. Nevertheless,
growing attention is given to potential negative effects deriving from the presence of harmful
pollutants. It is recognized that a (even very detailed) chemical characterization is not able to
predict ecotoxicity of a mixture. However, this can be directly measured by bioassays. Actu-
ally, the choice of the most suitable tests is still under debate. This paper presents a multilevel
characterization protocol of sewage sludge and other organic residues, based on bioassays and
chemical-physical-microbiological analyses. The detailed description of the experimental proce-
dure includes all the involved steps: the criteria for selecting the organic matrices to be tested
and compared; the sample pre-treatment required before the analyses execution; the chemical,
physical and microbiological characterisation; the bioassays, grouped in three classes (baseline
toxicity; specific mode of action; reactive mode of action); data processing. The novelty of this
paper lies in the integrated use of advanced tools, and is based on three pillars:
• the direct ecosafety assessment of the matrices to be reused.
• the adoption of innovative bioassays and analytical procedures.
• the original criteria for data normalization and processing.
