6. Agricultural use of sewage sludge
In order to minimize injestion of lead, cadmium and fluoride by livestock, the addition of these elements through sludge appliion to the surface should not exceed 3 times the 10 year average annual rates specified in Table 29. Sludge to be surface applied to grassland should not contain lead or fluoride individually in excess of 1200 and 1000 mg/kg dry solids, respectively.
