Effects of sewage sludge from Prague wastewater treatment plant on soil organisms
Original language description
Sewage sludge is very rich in nutrients and organic matter. This makes the spreading of this kind of waste on land as a fertilizer or an organic soil improver very suitable. Unfortunately, the sludge tends to concentrate heavy metals and organic compounds present in waste waters. This hampers its reuse in agriculture and then landfilling as well as incineration is used despite their environmental drawbacks. The Sewage Sludge Directive (86/278/EEC) regulates sludge use in such way to prevent harmful effects on soil, vegetation, animals and man. Limit values for heavy metals are defined in sewage sludge for agricultural use. The directive is now under revision and limits for more chemicals (AOX, POPs, detergents) will be added. However, only chemical measures are not sufficient for proper risk assessment and toxicity testing should be added to sludge use regulation. In our study, we evaluated the possibility of routine testing of sludge ecotoxicity.
