IMPLICATIONS OF RESEARCH ON THE UPTAKE OF PTEs
FROM SEWAGE SLUDGE BY GRAZING ANIMALS

FR/D0029

Feb 1998

SUMMARY

EXECUTIVE SUMMARY

The present report integrates the results from these research programmes, and discusses their implications for food safety and for animal health and production in relation to current limits on PTE concentrations in sludge-amended soils. Tissue accumulation of cadmium (Cd), lead (Pb) and copper (Cu) is assessed, both in a worst case situation with respect to soil intakes and soil PTE concentrations (soil at statutory limits) and under current operational condition. The main conclusions, taking into account PTE intakes from other sources, particularly herbage, are:
