PPCPs that have antibacterial or antibiotic properties can promote the development of multi-resistant germs. Not all, but some of these compounds are known to be toxic to sludge bacteria, explaining the rather similar trend among these two effect clusters. These negative environmental effects are of a less local nature since multi-resistant germs can spread through carrier species and damage to sludge bacteria in WWTPs can affect water quality on a supralocal level. The zeolite frameworks with the strongest affinities towards these species are BEA, IFR, MTW and MEL, which could find application in WWTPs to remove these compounds before wastewater enters the biological wastewater treatment stage.
