Any other information on results incl. tables
TSP amendment (5000 mg P/kg soil) resulted in a significant reduction of bioaccumulation of Pb and Zn. Rock phosphate (5000 mg P/kg soil)
reduced significantly the uptake of Zn in earthworms:Bioaccumulation factors in steady state (after 96h) (Cearthworm/Csoil) for 1 soil type (similar results for second soil):

Applicant's summary and conclusion
- Conclusions:
- Amendment of contaminated soils with TSP reduced availability of Pb and Zn to earthworms. Increased mortality of earthworms was observed after 96h at concentrations >5000 mg P/kg soil. Similar results were obtained with rock phosphates, although rock phosphate only reduced availability of Pb and not that of Zn.
- Executive summary:
Amendment of contaminated soils with TSP reduced availability of Pb and Zn to earthworms. Increased mortality of earthworms was observed after 96h at concentrations >5000 mg P/kg soil. Similar results were obtained with rock phosphates, although rock phosphate only reduced availability of Pb and not that of Zn.
