“…The MLOQs of the developed analytical method are between one and two orders of magnitude more sensitive in comparison to other methods dealing with the analysis of pesticides in soil (e.g., MLOQ (number of pesticides included in the respective study) in Geissen et al [ 15 ], 1–20 ng/g (36–75); Silva et al [ 8 ], 10 ng/g (76); Łozowicka et al [ 16 ], 5–10 ng/g (216); Kosubová et al [ 9 ], 3–10 ng/g (64); Hvězdová et al [ 10 ], 3–10 ng/g (68); Colazzo et al [ 53 ], 1–10 ng/g (30)). Only few studies reported MLOQs below 0.5 ng/g (Riedo et al [ 6 ], 0.04–36 ng/g (46); Lafay et al [ 11 ], 0.01–5.5 ng/g (31); Acosta-Dacal et al [ 13 ], 0.5–20 ng/g (218); Homazava et al [ 42 ], 0.1–2.9 ng/g (25); Pose-Juan et al [ 12 ], 0.2–0.7 ng/g (17); Pelosi et al [ 18 ], 0.01–5.5 ng/g (31)), at which most of the studies with MLOQs below 0.5 ng/g analyzed only between 17 and 46 pesticides.…”

A multi-residue trace analytical method is presented to accurately quantify 146 currently used pesticides in (agricultural) soils with varying soil properties. Pesticides were extracted using an optimized quick, easy, cheap, effective, rugged, and safe (QuEChERS) approach and chemical analysis was carried out by liquid chromatography coupled to tandem mass spectrometry (triple quadrupole). Quantification was based on matrix-matched internal standards calibration, using 95 isotopically labeled analyte analogues. In contrast to the common approach of method validation using soils freshly spiked with analytes shortly before the extraction, our method is additionally validated via an in-house prepared partly aged soil, which contains all target pesticides and via agricultural field soils with native pesticide residues. The developed method is highly sensitive (median method limit of quantification: 0.2 ng/g), precise (e.g., median intra-day and inter-day method precision both ~ 4% based on field soils), and true ((i) quantified pesticide concentrations of the partly aged soil remained stable during 6 months, were close to the initially spiked nominal concentration of 10 ng/g, and thus can be used to review trueness in the future; (ii) median freshly spiked relative recovery: 103%; and (iii) participation in a ring trial: median z-scores close to one (good to satisfactory result)). Its application to selected Swiss (agricultural) soils revealed the presence of in total 77 different pesticides with sum concentrations up to 500 ng/g. The method is now in use for routine soil monitoring as part of the Swiss Action Plan for Risk Reduction and Sustainable Use of Plant Protection Products. Graphical abstract

“…In Uruguay, the presence of pesticide residues has been reported in watercourses and drinking water (37)(38) , in soil (39)(40) , in the air (41) , in beehives and in component parts of beehives (42)(43)(44)(45) , and in agrifoods (46)(47)(48) . Furthermore, there are several studies on the effect of the use of pesticide products at the biota level in environmental compartments (49)(50)(51)(52)(53)(54)(55)(56)(57) .…”

Pesticides have become an essential input for agriculture in the last decades. However, the growing concern about the potential impact produced by such dependency on human health and the environmental level has led to strong questionings about the use of pesticides worldwide. This paper aims to analyze the use of pesticides in Uruguay's agriculture and their potential risks with an emphasis on ecotoxicological risks. For such purposes, data on imports and use of pesticides in Uruguay and some other agricultural regions corresponding to the last two decades (2000-2020) were collected. In addition, information on the risks associated with the use of different pesticides compiled in the Pesticide Properties Database of the University of Hertfordshire was reviewed, as well as information generated by related national and international research. The information collected indicates high intensity usage of pesticides in Uruguayan agriculture and uncertainties in relation to environmental risks that may arise from the current forms of use.
