Abstract

The overuse of soil, for example by intensive agricultural practices, causes soil erosion, desertification and deterioration, and makes the soil inaccessible to future generations as a resource. One possible way to reverse these negative effects is by increasing the organic carbon and nitrogen stocks of the soil with organic amendments such as sewage sludge; this has been recommended as one possible method of sludge utilization by the EU Sewage Sludge Directive 86/278/EEC (SSD). However, as the end-product of wastewater purification processes, sewage sludge contains large amounts of toxic substances, including those that are not subjected to any regulation such as antibiotics. Hence in recent years, the use of sewage sludge has become a major safety concern for its potential risk to the environment and human health.
