Mechanisms and reversibility of glyphosate and phosphorus ligands sorption on Al2O3: Experimental evidence and computational modeling Open
The environmental fate and risk of glyphosate (Gly) are critically influenced by its retention at soil-water interfaces. While aluminum (oxyhydr)oxides (Al2O3, Al(OH)3, AlOOH) are abundant in soils, their adsorption mechanisms for Gly have…

Facies and depositional environments of a Holocene floodplain: Implications for modeling biogeochemical reactions in aquifers Open
Aquifer sediments, which are formed under varying depositional conditions, exhibit significant heterogeneity in their sedimentary architecture, causing variability in their hydraulic and biogeochemical properties. The spatial arrangement o…

Holocene Floodplain Sediments: From depositional processes to biogeochemical pollutant turnover Open
Aquifer sediments, formed under varying depositional conditions, exhibit significant heterogeneity in their sedimentary architecture causing variability in their hydraulic and biogeochemical properties. The spatial arrangement of these pro…

 Unravelling the Spatial Variability and Complexity of Denitrification in Heterogeneous Aquifer Sediments   Open
Nitrate pollution of groundwater represents a critical environmental concern, with many aquifers exceeding ecological and health-related concentration limits. Microbial driven denitrification represents the primary mechanism for nitrate at…

Glyphosate is a transformation product of a widely used aminopolyphosphonate complexing agent Open
Diethylenetriamine penta(methylenephosphonate) (DTPMP) and related aminopolyphosphonates (APPs) are widely used as chelating agents in household and industrial applications. Recent studies have linked APP emissions to elevated levels of th…

In-situ formation of glyphosate and AMPA in activated sludge from phosphonates used as antiscalants and bleach stabilizers in households and industry Open
The herbicide glyphosate and aminomethyl phosphonic acid (AMPA), a transformation product of glyphosate and other aminopolyphosphonates are widespread pollutants in European rivers. We recently showed that besides rain-driven input after a…

Influence of organophosphonates as alternative P-sources on bacterial transformation of glyphosate Open
Glyphosate biotransformation under phosphorus (P)-limiting conditions has been demonstrated for numerous bacterial strains. However, besides glyphosate bacteria can utilize a broad spectrum of other biogenic and synthetic organophosphorus …

Glyphosate is a transformation product of a widely used aminopolyphosphonate complexing agent Open
We demonstrate for the first time that the broad-spectrum herbicide glyphosate is a stable transformation product during manganese-driven oxidation of diethylenetriamine penta(methylenephosphonate) (DTPMP), a complexing agent widely used i…

Intrinsic potential and activity of nitrate turnover examined for different hydrogeological aquifer settings Open
Nitrate (NO3-) is one of the most serious contaminants in groundwater, frequently deteriorating water quality and groundwater use as drinking water. Nitrate can, at specific environmental conditions, be removed within the subsurface enviro…

Does the number of cells of individual strains correlate with their contribution to the total substrate turnover within a microbial community? Open
In a synthetic binary culture, cell numbers derived by qPCR did not reflect the contribution of individual strains to the total substrate turnover.

Application of carbon compound-specific isotope analysis (carbon-CSIA) to investigate microbial transformation of glyphosate Open
Glyphosate (N-(phosphonomethyl)glycine) is the most applied herbicide in the world with an estimated annual application of 740 to 920 kt by 2025 extrapolating the current weed management strategy. Overuse of glyphosate in agriculture has l…

Expanding the calibration range of compound‐specific chlorine isotope analysis by the preparation of a <sup>37</sup> Cl‐enriched tetrachloroethylene Open
Rationale The recent development of reliable GC/qMS methods for δ 37 Cl compound‐specific stable isotope analysis (CSIA) paves the way for dual carbon–chlorine isotope analysis of chlorinated ethenes and thus allows deeper insights into un…

Isotopic Labeling Reveals Microbial Methane Oxidation Coupled to Fe(III) Mineral Reduction in Sediments from an As-Contaminated Aquifer Open
Although arsenic (As) groundwater contamination in South and Southeast Asia is a threat to human health, mechanisms of its release from sediment to groundwater are still not fully understood. In many aquifers, Fe(III) minerals are often th…
