Occurrence and fate of TMDD in wastewater treatment plants in Germany

The occurrence and fate of 2,4,7,9-tetramethyl-5-decyne-4,7-diol (TMDD) was investigated in four wastewater treatment plants (WWTPs) in Germany. The concentration of TMDD in influents and effluents in the WWTPs ranged from 134 ng/L to 5846 ng/L and from

► We examine the concentrations and loads of TMDD in 4 wastewater treatment plants.
► TMDD is introduced to the sewage through households and industrial dischargers.
► TMDD is partially removed from the wastewater.
► The elimination rates varied between 33% and 68%.
