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 suspended MnO lead formation glyphosate, which remains stable after complete conversion. Glyphosate yields vary conditions reach up 0.42 mol%. The ubiquitous presence natural waters wastewater systems underscores potential importance Mn-driven a previously overlooked source aquatic systems. These findings challenge current paradigm application sole contamination necessitate reevaluation resource protection strategies.

Abstract Organophosphonates (OPs) are widely used as chelating agents in domestic and industrial applications. While regarded hardly biodegradable, OPs can undergo abiotic transformation with phosphate (PO 4 3− ) a main product. As some suspected precursors of glyphosate surface waters, their environmental fate is current interest. Due to analytical challenges posed by quantification individual OPs, monitoring PO formation proxy monitor OP transformations. The molybdenum blue (MB) method, employing UV/Vis spectroscopy, frequently for due its sensitivity operational simplicity. However, while interference certain inorganic ions well-documented, the effects on accuracy MB method remain unexplored.
