Investigation of Organic Compounds in Sludge - Persistent Organic Pollutants; Steroid Oestrogens; and Selected Pharmaceuticals

Price: £100  

This is the fourth UKWIR study on the occurrence of organic chemicals in digested sewage sludge. The study was driven by: An update by the CEC to the Persistent Organic Pollutants (POPs) regulations, which includes limits on sludge concentrations for some compounds; and An increased awareness of the presence of steroid oestrogens and pharmaceuticals in sludge. The project has involved the sampling and analysis of digested sludge and return liquors from 16 sludge treatment centres (STCs).
The POP compounds were not detected in any of the sludge samples. The risk posed by the proposed POP regulations limits is considered low. Steroid oestrogens and pharmaceuticals were detected to varying degrees. A high level risk assessment suggests the risk posed by the compounds to be low, however, as more information on soil effects is developed it is suggested that the risk assessment may need to be revisited in the future.
