“…Recent studies showed the presence of emerging contaminants such as cyanoguanidine (CG), n-(3-(dimethylamino)-propyl)methacrylamide (MAPMA), 2-methyl-2-propene-1-sulfonic acid (MPSA), benzyldimethylamine (BDMA), benzyltrimethylammonium (BETMAC), adamantan-1-amine (ATA), 1,3-di- o -tolylguanidine (DIOTOG), 1,3-diphenylguanidine (DPG), 4-hydroxy-1-(2-hydroxyethyl)-2,2,6,6,-tetramethylpiperidine (HHTMP), melamine (MEL), 2-acrylamido-2-methylpropane sulfonate (AAMPS), dimethylbenzenesulfonic acid (DMBSA), p -toluenesulfonic acid (PTSS) and trifluoromethanesulfonic acid (TFMSA) in surface and groundwater with concentrations in the ranges of ng/L and μg/L [ [4] , [5] , [6] , [7] , [8] , [9] , [10] ]. In addition, 53% of the detected emerging PM substances were above 0.1 μg/L [ 4 , 8 , 11 ]. In Europe, there is an ongoing discussion to register PM substances under REACH legislation (registration, evaluation, authorization and restriction of chemicals (EC 1907/2006) regulation Annex XIII), similar to the previously regularized PBT (persistence, bioaccumulative and toxic) substances.…”
