| Review: |
These are the results of a coordinated research project organised by the Joint FAO-IAEA Division of Nuclear Techniques in Food and Agriculture. They fulfil the objects of the project: to characterise both radiated and non-irradiated sludge in terms of their physical and chemical properties, contents of pathogenic organisms, and toxic organ compound; to quantify the benefits in terms of increasing crop yields, improving soil physical properties and chemical fertility, including macro- and micro-nutrient availability; and to assess the extent of contamination of soils and crops by sludge-derived heavy metals. |
