Concentrations of glyphosate, its degradation product, aminomethylphosphonic acid, and glufosinate in ground- and surface-water, rainfall, and soil samples collected in the United States, 2001-06

Abstract

Map showing location of streamflow-gaging stations where samples were collected for analysis of glyphosate, its degradation product, aminomethylphosphonic acid, and glufosinate as part of the U.

Association between Cancer and Environmental Exposure to Glyphosate

“…Both pretreatment and analysis of pesticides were performed under international regulations using liquid chromatography-mass spectrometry [7] [8]. A dosage of arsenic (As) was conducted in domestic water network using hydride generation atomic absorption spectrometry.…”

Impact of phosphate on glyphosate uptake and toxicity in willow

“…This cultivar's rapid, voluminous biomass production, associated with its high tolerance to stress factors (i.e., soil contamination by metals and organic pollutants) [27], together constitute important features of plant species being considered as candidates for phytoremediation programs [28], particularly in the context of riparian buffer strips. [29]) and Argentina (0.5 -5 mg kg -1 [32]). Phosphate doses were chosen according to common fertilization practices in agricultural fields [12,33,34].…”

Herbicide Contamination of Freshwater Ecosystems: Impact on Microbial Communities

“…This degradation generally occurs more slowly in water, because it contains fewer microorganisms than soil (Ghassemi et al, 1981). Glyphosate and its main degradation product AMPA are among the most common pesticides detected in water-pollution monitoring (Scribner et al, 2007). However, although glyphosate is the main source of AMPA, it is not its only source (Trass & Smit, 2003), since phosphonate compounds can also be degraded to form AMPA (Novack, 1997;Skark et al, 1998;Kolpin et al, 2006;Botta et al, 2009).…”
