Fate of pharmaceutical residues - in sewage treatment and on farmland fertilized with sludge

Overall aim: if sludge amended on farmland could be a significant source for emission of pharmaceuticals to the environment

Detected levels of pharmaceuticals residues in the samplesSludge – 15 of 24 pharmaceuticals (1.9 – 1000 ng/g dw)Soil – 4 of 24 pharmaceuticals (0.4-4.9 ng/g dw)Soil water (Lysimeter) – only Caffeine in one sample (69 ng/L)
ConclusionsSludge amended on farmland is a insignificant source for emissions
Study implies that the investigated pharmaceuticals are retained and eventually degraded at the surface of the soil.
