Effects of the fungicide tebuconazole on microbial capacities for litter breakdown in streams.

Streams draining agricultural basins are subjected to the input of fungicides which can affect aquatic microbial communities. We analyzed the effect of the fungicide tebuconazole (TBZ) on Alnus glutinosa and Populus nigra litter breakdown by aquatic microorganisms. For six weeks, fungal and bacterial responses were analyzed in indoor stream channels subjected to TBZ-contaminated (33.
