“…However, unlike for boscalid and penconazole, transformation processes predominated for metazachlor, as demonstrated by the measurement of its TPs. The low recoveries obtained for boscalid and penconazole after the flushings may be explained by their low leaching 35 potential (USEPA, 2003;European Food Safety Authority (EFSA), 2008;Marín-Benito et al, 2015). As for the tracers, Br recovery was the highest, as expected given its most conservative character.…”

Abstract. Hydrological tracers have been recently used as a low-cost approach to study the fate and transport of pesticides in constructed wetlands. Yet, internal temporal and spatial mechanisms that dominate their transport and dissipation in such environments are still not fully understood. We have applied three tracers with different sorptive and reactive properties: bromide (Br), uranine (UR) and sulforhodamine B (SRB) to investigate dominant temporal and spatial transport and dissipation processes of three selected pesticides: boscalid, penconazole and metazachlor in a model constructed wetland system designed to perform high vertical-resolution sampling and monitoring on a long-term basis. The experimental observations revealed that two different preferential flow paths developed, one due to the constructional design of the inflow and the other one due to the influence of the free water at the surface along with the plants. Transport of solutes was driven by the injections and dominated for Br, UR and metazachlor. The final mass balance highlighted that the main dissipation pathways were sorption, transformation and plant uptake. Sorption was detected immediately after the injection of solutes, while transformation was enhanced by the presence of plants and the promotion of aerobic conditions. The detection of metazachlor transformation products confirmed the contribution of transformation to metazachlor dissipation, whereas boscalid and penconazole mainly experienced sorption processes. The use of hydrological tracers together with selected pesticides and coupled with high vertical-resolution sampling and monitoring proved to provide valuable information about transport vectors and dissipation processes of pesticides in a vegetated redox-dynamic environment on a long-term basis and detailed spatial scale.

“…Thus, its extrapolation to modeling studies with amended soils could under-or overestimate the effect of temperature on pesticide degradation rates and not properly reproduce their environmental fate (Marín-Benito et al, 2015) in a model of sustainable agriculture.…”

“…These studies have been reported for compounds with different properties, and they have generally been conducted under laboratory conditions. These laboratory assays are usually based on two types of soil columns: undisturbed soil cores taken directly in the field to preserve the soil macrostructure within the soil profile [120,121], or packed soil columns [78,96]. The effect of organic amendments on the leaching of pesticides is assessed in both types of columns after washing with a continuous flow of water or aqueous solution of CaCl 2 (saturated flow) or a discontinuous flow (saturated/non-saturated flow).…”

The management of large volumes of organic residues generated in different livestock, urban, agricultural and industrial activities is a topic of environmental and social interest. The high organic matter content of these residues means that their application as soil organic amendments in agriculture is considered one of the more sustainable options, as it could solve the problem of the accumulation of uncontrolled wastes while improving soil quality and avoiding its irreversible degradation. However, the behavior of pesticides applied to increase crop yields could be modified in the presence of these amendments in the soil. This review article addresses how the adsorption–desorption, dissipation and leaching of pesticides in soils is affected by different organic residues usually applied as organic amendments. Based on the results reported from laboratory studies, the influence on these processes has been evaluated of multiple factors related to organic residues (e.g., origin, nature, composition, rates, and incubation time of the amended soils), pesticides (e.g., with different use, structure, characteristics, and application method), and soils with different physicochemical properties. Future perspectives on this topic are also included for highlighting the need to extend these laboratory studies to field and modelling scale to better assess and predict pesticide fate in amended soil scenarios.
