Abstract: | Background, aim, and scope In this work, an environmental risk assessment of reusing organic waste of differing origins and raw materials as agricultural
fertilizers was carried out. An inventory of the heavy metal content in different organic wastes (i.e., compost, sludge, or
manure) from more than 80 studies at different locations worldwide is presented. |
