Introduction to Ecological Risk Assessment

摘要: The topsoil is the most biologically diverse part of earth, harbouring more than one billion organisms per square meter. These soil live in extremely complex mutual interaction and, additionally, similarly interactions with their physical and chemical environment. Although not always acknowledged by general public, ecosystems perform so-called Ecosystem Services which are very important for society. Some these Services, described detail this chapter, structuring, humus formation, nutrient supply, cleaning function, disease control, – only recently recognised energy-related processes. conclusion to be drawn that intensive communication about Ecological Risk Assessment a necessity, both guarantee appropriate ecological protection on political agenda justify ecosystem costs involved tax payer. Soil contamination has big impact ecosystem. an useful process supporting decisions taken concerning contaminated sites. target Health (the preferred state) rather Integrity unimpaired condition), ideally at level whole factors relate effects will introduced such as bioavailability, food sealing, resilience recovery, adaptation, land use, secondary poisoning, web approach, wildlife protection, scale contaminant pattern, spatial planning. Finally, insight provided how actually works practice.
