Glyphosate and AMPA concentrations in wind-blown material under field conditions [PDF]

, 2018
Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle-farming country, which has increased its productivity in the last few ...

Glyphosate and aminomethylphosphonic acid are not detectable in human milk [PDF]

The American Journal of Clinical Nutrition, 2016
Although animal studies have shown that exposure to glyphosate (a commonly used herbicide) does not result in glyphosate bioaccumulation in tissues, to our knowledge there are no published data on whether it is detectable in human milk and therefore consumed by breastfed infants.We sought to determine whether glyphosate and its metabolite ...

Human Biomonitoring of Glyphosate Exposures: State-of-the-Art and Future Research Challenges

Toxics, 2020
Glyphosate continues to attract controversial debate following the International Agency for Research on Cancer carcinogenicity classification in 2015. Despite its ubiquitous presence in our environment, there remains a dearth of data on human exposure to

Validation of a Liquid Chromatography Coupled to Mass Spectrometry Method for Glyphosate and Aminomethylphosphonic Acid in Urine for Human Biomonitoring Using Combined Hybrid Anion-Exchange and Hydrophilic Interaction Liquid Chromatography

Separations, 2023
Glyphosate-based herbicides are the most widely used pesticides in the world; however, the toxicity of glyphosate (GlyP) toward humans, especially its carcinogenicity, is controversial.

Turfgrass species response exposed to increasing rates of glyphosate application [PDF]

, 2009
To investigate the response of nine turfgrass species exposed to increasing rates of glyphosate application, the dry matter production, visual leaf injury symptoms (e.g., chlorosis and necrosis) and the concentrations of shikimate and mineral nutrients ...

A Glyphosate Pulse to Brackish Long-Term Microcosms Has a Greater Impact on the Microbial Diversity and Abundance of Planktonic Than of Biofilm Assemblages

Frontiers in Marine Science, 2019
The widespread herbicide glyphosate has been detected in aquatic coastal zones of the southern Baltic Sea. We monitored community dynamics in glyphosate-impacted chemostats for 20 weeks to evaluate the potential impact of the herbicide on free-living and

Determination of glyphosate and aminomethylphosphonic acid in soybean samples by high performance liquid chromatography using a novel fluorescent labeling reagent [PDF]

, 2013
A highly sensitive pre-column derivatization HPLC method for simultaneous determination of glyphosate (GLYP) and its major metabolite aminomethylphosphonic acid (AMPA) in soybean samples was developed.

Sorption and desorption of glyphosate in Mollisols and Ultisols soils of Argentina [PDF]

, 2018
In Argentina, glyphosate use has increased exponentially in the past years due to the widespread adoption of no-till management combined with genetically modified glyphosate-resistant crops.

Barium titanate nanoparticles used as second harmonic radiation imaging probes for cell imaging [PDF]

, 2009
Luminescent markers play a key role in imaging techniques for life science since they provide a contrast mechanism between signal and background. We describe a new type of marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO_3 ...

Estudo do comportamento eletroquímico de substâncias complexantes utilizando eletrodo de cobre Study of electrochemical behavior of complexing compounds using copper electrode

Química Nova, 2009
Copper electrode can be used for determination of complexing compounds through complexation reactions between Cu(II) and the analites. In this work some studies with three compounds were performed: glycine (precursor of glyphosate synthesis), herbicide ...
