Transfer of Cadmium into Sewage Sludge
Approximately 20% of cadmium present in sewage sludge is derived from domestic sources which have been outlined in this chapter. Concentrated human waste can contain a high intensity of Cadmium. This level is however extremely variable depending on the location, but a mean level of 29 ppm dry matter appears to be a fairly accurate concentration.
The remaining 80% originates from industrial sources.
