Drug residues

The risks of spreading pharmaceuticals in waste water and sludge . Today's treatment plants were not built to break down all drug residues. Tyréns is participating in the Örebro University development project “Biologiska effekter av läkemedelsrester” (Biological effects of pharmaceutical residues) to identify the possible risks to health.

The task of Tyréns in the development project covers the development of a risk analysis model that could be used in social and city planning. This development project is the first of its kind where consequence analyses of human cells are carried out. The principal source of finance for the development project is the KK foundation (Swedish Knowledge Foundation).

The presence of pharmaceutical residues in the environment is a growing problem, and the result of deficient waste management. In connection with the routine sampling of watercourses over many years, local authorities have identified an increasing level of medicaments in the water. Tyréns was asked by Örebro University to participate in a study to examine the biological effects of pharmaceutical residues.

Tyréns is taking part in collecting samples in respect of the distribution in watercourses close to treatment plants, and the sludge in such plants. On the basis of the sampling results, a risk analysis is prepared in respect of society, towns and cities. The analysis leads to a risk assessment model which looks at where risks exist for the intake of media, such as food and water, that can contain pharmaceutical residues. The completed optimised risk analysis model can then be used in future social planning.

The plan is to continue and perform analyses and their equivalent risk analyses for the spread of perfluorinated compounds (such as PFOS, etc.) in water and sludge.
