Abstract Diethylenetriamine penta(methylenephosphonate) (DTPMP) and related aminopolyphosphonates (APPs) are widely used as chelating agents in household industrial applications. Recent studies have linked APP emissions to elevated levels of the herbicide glyphosate European surface waters. However, transformation processes products APPs environment largely unknown. We show that is formed from DTPMP by reaction with manganese at near neutral pH pure water wastewater. Dissolved Mn 2+ O 2 or...
<title>Abstract</title> We demonstrate for the first time that broad-spectrum herbicide glyphosate is a stable transformation product during manganese-driven oxidation of diethylenetriamine penta(methylenephosphonate) (DTPMP), complexing agent widely used in household and industry applications. Glyphosate formation was observed at circumneutral pH (i) presence MnO<sub>2</sub> (with without dissolved O<sub>2</sub>) as well (ii) Mn<sup>2+</sup> O<sub>2</sub>. Maximum yields varied with...
<title>Abstract</title> The most widely used herbicide glyphosate contaminates surface waters around the globe. Being toxic to aquatic organisms and a possible carcinogenic, mitigation strategies attempt reduce river contamination, but their impact is not evaluated. Investigating long-term time series, we discovered that – in contrast USA water concentration patterns Europe contradict dominant input from application. Our large meta-analysis clearly shows for decades, main source of has been...

<title>Abstract</title> The most widely used herbicide glyphosate contaminates surface waters around the globe. Both agriculture and urban applications are discussed as sources for glyphosate. To better delineate these sources, we investigated long-term time series of concentrations its main transformation product aminomethylphosphonic acid (AMPA) in a large meta-analysis about 100 sites USA Europe. U.S. data reveal pulses AMPA when discharge river is high, likely indicating mobilization by...
