or totally inhibited depending on the concentrations of dissolved or
particulate organic carbon, or of chloride, iron or bromide ions
[GE 10, GIT 11, KNA 05]. On the contrary, quinolones/
fluoroquinolones, sulfonamides and macrolides are stable molecules.
Their properties of adsorption to particles favor their persistence in
sediments, biofilms and periphytons, and in filter feeders [BRO 06,
HIR 99, LIN 04, WAT 09, WUN 11].
