Resumo: Soil ecosystems are nowadays exposed to several physical, chemical and biological stressors, which are directly or indirectly related to anthropogenic activities. This chapter covers how contaminants affect the soil ecosystem structure, changing soil functions and services. Soil ecosystem structure is constituted by dynamic interactive abiotic and biotic compartments, dependent on major key factors like water and light. By changing this balanced system, soil functions are also impaired as they are strictly dependent on this structure and biodiversity. Soil functions include carbon transformations, nutrient cycling, maintenance of the structure itself, and regulation of biological populations. Activities like mining, agriculture, forestry or waste disposal are often responsible for the unbalance of soil structure and functions, by jeopardizing majorly the functional biodiversity compartment of the ecosystem. Therefore, the provision of goods along with ecosystem services will be also affected. Valuing soil ecosystem services is a difficult task and often lacking at the policymaking level, as the costs of services losses can go unnoticed. Therefore new strategies should be implemented to bring the concepts of structure, functions, services and goods on board at the regulation level.
