“…6B) was the only one in which the glyphosate concentration was higher than the AMPA concentration in this stream. The other samples appear to correspond to baseflow conditions, at which times perhaps discharging groundwater, which is expected to contain older, AMPAdominated residues of glyphosate, may be important (Van Stempvoort et al, 2014). Although 20 Mile Creek does receive treated municipal wastewater discharge (Table 2) at an upstream location it does not appear to be impacted by it to the same degree as other streams in Fig.…”

“…Van Stempvoort et al (2014) reported the presence of glyphosate and AMPA in riparian groundwater sampled from five sites in southern Ontario. Each were found only in about 10% of the samples overall, but each were detected in 50% or more of the groundwater samples obtained from shallow depths along two streams in the City of Burlington.…”

“…Glyphosate and aminomethylphosphonic acid (AMPA) were analyzed using the ion chromatography, electrospray ionization, tandem mass spectrometry (IC/MS/MS) method reported by Van Stempvoort et al (2014). The artificial sweetener acesulfame was included as another analyte in the same method reported by Van Stempvoort et al (2011b).…”

“…Stems, leaves and beans of glyphosate resistant soy are contaminated with glyphosate. Moreover, because of the extensive use of glyphosate, it is frequently detected in water, rain and air [4,5]. Recently, glyphosate residues were tested in urine and different organs of dairy cows as well as in urine of hares, rabbits and humans in different concentrations [6].…”

SummaryGlyphosate residues in different organs and tissues as lungs, liver, kidney, brain, gut wall and heart of malformed euthanized one-day-old Danish piglets (N= 38) were tested using ELISA. All organs or tissues had glyphosate in different concentrations. The highest concentrations were seen in the lungs (Range 0.4-80 µg/ml) and hearts (Range 0.15-80 µg/ml). The lowest concentrations were detected in muscles (4.4-6.4 µg/g). The detection of such glyphosate concentrations in these malformed piglets could be an allusion to the cause of these congenital anomalies. Further investigations are urgently needed to prove or exclude the role of glyphosate in malformations in piglets and other animals.

Abstract:The application of pesticides indoors and on agricultural lands increased dramatically in recent years in the Jazan area (Saudi Arabia) to control termites and the vectors of diseases, such as Rift Valley Fever (RVF) and malaria. This practice increased the potential risk of pesticide contamination of surface water and groundwater. In this study, samples of 44 wells and 3 dams were collected; the samples were analysed for the presence of 15 pesticides used in the Jazan area. The results showed that the most detected compounds in the surface water samples were diazinon, Dichlorodiphenyltrichloroethane (DDT), fenitrothion and cyfluthrin, with average concentrations of 0.098, 0.104, 0.321 and 0.394 µg L −1 , respectively. In the groundwater samples, the most detected insecticides were diazinon, dieldrin and fenthion, with average concentrations of 0.117, 0.005 and 0.472 µg L −1 , respectively. In general, detected concentrations of organophosphorus insecticides slightly exceeded the allowed Maximum Residue Limit (MRL) of the European Union, which is 0.1 µg L −1 , in some samples. However, the findings of this study about the safety of water resources in the Jazan area were not alarming because the detected concentrations were below the MRL and lower than the limit of the sum of all individual compounds detected in the same sample. More extended investigations are highly recommended.
