“…Glyphosate is highly soluble in water, and its half-life can vary from a few days to 60 days, depending on the conditions in the environment (Vereecken, 2005). Mörtl et al (2013) reported that the glyphosate concentrations in the surface and ground water were nearly 1 mg L À1 within some samples from Békés County in Hungary. Moreover, Sobrero et al (2007) found that the concentration of glyphosate in the Argentine water bodies covered a range of 0.1-80 mg L À1 , while Peruzzo et al (2008) reported that the levels of glyphosate were 0.1-0.7 mg L À1 in water bodies located near the agricultural plantations of the Pampa Region (Buenos Aires, Argentina), which are higher than the drinking water limits recommended by the US Environmental Protection Agency (EPA) (0.7 mg L À1 ) or European standard (0.1 lg L À1 ) (WHO, 2005;CCME, 2012).…”

“…Given its widespread application, glyphosate transport and the associated contamination risk are a global issue. Glyphosate residues have been found in waters in Denmark, Hungary and Brazil . In addition, a recent monitoring campaign by the United States Geological Service revealed widespread contamination throughout many Midwestern states, with glyphosate detected in >50% of streams ( n tot = 1508) and ditches/drains ( n tot = 374) sampled .…”

BACKGROUND Biochar, a carbon‐rich product of biomass pyrolysis, could limit glyphosate transport in soil and remediate contaminated water. The present study investigates the sorption/desorption behavior of glyphosate on biochars prepared from different hardwoods at temperatures ranging from 350 to 900 °C to elucidate fundamental mechanisms. RESULTS Glyphosate (1 mg L−1) sorption on biochars increased with pyrolysis temperature and was highest on 900 °C biochars; however, total sorption was low on a mass basis (<0.1 mg g−1). Sorption varied across feedstock materials, and isotherms indicated concentration dependence. Biochars with a greater fraction of micropores exhibited lower sorption capacities, and specific surface groups were also found to be influential. Prepyrolysis treatments with iron and copper, which complex glyphosate in soils, did not alter biochar sorption capacities. Glyphosate did not desorb from biochar with CaCl2 solution; however, up to 86% of the bound glyphosate was released with a K2HPO4 solution. CONCLUSION Results from this study suggest a combined impact of surface chemistry and physical constraints on glyphosate sorption/desorption on biochar. Based on the observed phosphate‐induced desorption of glyphosate, the addition of P‐fertilizer to biochar‐amended soils can remobilize the herbicide and damage non‐target plants; therefore, improved understanding of this risk is necessary. © 2017 Society of Chemical Industry

Pesticides can exert negative effects on aquatic organisms at very low concentrations. While several prey taxa are frequently used as models in ecotoxicology studies, there is little information about the pesticide-sensitivity of predators. We examined the effects of a frequently applied glyphosate-based herbicide on two common aquatic predators: larval Aeshna cyanea dragonflies and adult male Lissotriton vulgaris newts, which are top predators in ephemeral water bodies lacking fishes. We exposed predators to the herbicide for 18 days under laboratory conditions and measured potential effects on survival, activity, body mass and predatory activity. To maximize detectability of effects, we applied the herbicide at a concentration of 6.5 mg a. e. glyphosate/L, corresponding to the highest concentration expected in nature. Our results showed that the tested herbicide formulation did not have severe effects on any of the measured fitness-related traits. Results of the present study support the hypothesis that the tested species are insensitive to the herbicide and are able to fulfil their important ecological role of top-down regulation even in highly contaminated habitats. However, potential long-term or indirect effects of the herbicide on the fitness of aquatic predators remain unknown.
