![]() ![]() Diverse applications result in a variety of different sources and entry pathways (Burkhardt et al., 2011 Wieck et al., 2018 Paijens et al., 2021). However, this is not the case for biocides applied in an urban context. Pesticides in agriculture have been intensively characterized regarding their sources (Reichenberger et al., 2007), environmental compartments for transformation (Fenner et al., 2013 Gassmann et al., 2013), and pathways to surface and underground waters (Doppler et al., 2012 Greiwe et al., 2021). Investigated since first usage of, e.g., diuron (Peck et al., 1980 Giacomazzi and Cochet, 2004) and terbutryn (Wu et al., 1974 Donati and Funari, 1993 Musgrave et al., 2011). InĪgriculture, the environmental fate of selected pesticides has been The same active substances used as pesticides in agriculture can act as biocides in urban areas. They are, for example, used in renders and paints to inhibit the growth of microorganisms (e.g., algae and fungi) on facades (Sauer, 2017). ![]() This study contributes to expanding knowledge on their entry and distribution and, thus, eventually towards reducing emissions.īiocides are bioactive substances and are regulated by Regulation (EU) no. 528/2012 (European Parliament and Council, 2012). The applied two-step approach determined sources and pathways of biocide and their TPs. ![]() This suggests a high leaching potential of terbutryn. One of the pipes collecting infiltrated water through soil concentration showed the highest concentrations of terbutryn and two of its TPs (terbutryn-desethyl and terbuthylazine-2-hydroxy). In two other drainage pipes collecting infiltrated water through soil, terbuthylazine-2-hydroxy was additionally detected. In one drainage pipe collecting road runoff, only diuron-desmethyl and terbutryn-desethyl were detected. Diuron and terbutryn were found in three drainage pipes representing different entry pathways of biocides. Sampling of rain downpipes from flat roofs identified additional sources of all biocides and two TPs of terbutryn and one TP of diuron. We confirmed expected sources, i.e., facades. In standing water in a swale, we found high concentrations of diuron (174 ng L −1) and terbutryn (40 ng L −1) above PNEC for surface water. Monitoring focuses on the analysis of selected biocides and TPs by liquid chromatography–mass spectrometry/mass spectrometry (LC-MS/MS) in water samples taken from facades, rainwater pipes, drainage, and storm water infiltration systems. ![]() Sampling utilizes existing urban water infrastructure representative for decentralized storm water management inĬentral and northern Europe and applies a two-step approach to (a) determine the occurrence of biocides above water quality limits (i.e., predicted no-effect concentration, PNEC) and (b) identify source areas and characterize entry pathways into surface and groundwater. We investigate emissions of commonly used biocides (terbutryn, diuron, and octylisothiazolinone – OIT) and some of their transformation products (TPs diuron-desmethyl, terbumeton, terbuthylazine-2-hydroxy, and terbutryn-desethyl) from a 2 ha residential area 13 years after construction has ended. This study identifies individual sources and entry pathways in a small-scale urban area. Also, don't forget to mention Hubbiz to Hess Garage Inc.Biocides used in film protection products leaching from facades are known to be a potential threat to the environment.
