“…The peak concentrations were always higher after the application of a saturatedunsaturated flow than after a saturated flow was applied, and the leaching kinetics was more rapid. This behavior is consistent with the evolution of cymoxanil adsorbed in non-extractable form or mineralized when a saturated-unsaturated flow was applied (Álvarez-Martín et al, 2016b), and it is consistent with the amounts leached, retained, and mineralized under these conditions ( Table 5).…”

“…Both fungicides enter the soil after their application to plants, and in areas of intense fungicide use in Spain they have been detected in surface and ground waters in higher concentrations than those permitted by EU legislation (0.1 µg L -1 ) (Herrero-Hernández et al, 2013, as well as in other areas of the world (Battaglin et al, 2011;De Geronimo et al, 2014;Montagner et al, 2014). These results provided support for the studies on the immobilization and dissipation of both fungicides in soil amended with the organic SMS residue considered by Álvarez-Martín et al (2016a and2016b) for proposing a strategy to prevent water contamination by these compounds. A range of SMS doses were used in these studies, and an increase in the adsorption coefficients of up to >20 times (tebuconazole) or >40 times (cymoxanil) was obtained for soils amended with SMS at rates between 2% and 75%.…”

“…However, the adsorbed compound could be bioavailable, as mineralized amounts up to ≈18% (S), ≈12% (S+SMS5) and ≈10% (S+SMS50) were detected under both flows ( Table 5). The dissipation mechanism of cymoxanil in SMS-amended soils studied by Álvarez-Martín et al (2016b) indicated that the mineralization of cymoxanil in unamended and SMSamended soils increased over time, reaching an amount >50% in S and S+SMS5 after one-month incubation, and >25% in S+SMS50. These authors have reported a decrease in the water extractable cymoxanil fraction over time, being lower in S+SMS50 than in S and S+SMS5, while the non-extractable fraction of cymoxanil increased over time.…”

A study has been conducted on the leaching of two fungicides, tebuconazole and cymoxanil, in a soil amended with spent mushroom substrate (SMS), with an evaluation of how different factors influence this process. The objective was based on the potential use of SMS as a biosorbent for immobilizing pesticides in vulnerable soils, and the need to know how it could affect the subsequent transport of these retained compounds. Breakthrough curves (BTCs) for C-fungicides, non-incubated and incubated over 30days, were obtained in columns packed with an unamended soil (S), and this soil amended with SMS at rates of 5% (S+SMS5) and 50% (S+SMS50) under saturated and saturated-unsaturated flows. The highest leaching of tebuconazole (>50% of the total C added) was found in S when a saturated water flow was applied to the column, but the percentage of leached fungicide decreased when a saturated-unsaturated flow was applied in both SMS-amended soils. Also a significant decrease in leaching was observed for tebuconazole after incubation in the column, especially in S+SMS50 when both flows were applied. Furthermore, cymoxanil leaching was complete in S and S+SMS when a saturated flow was applied, and maximum peak concentrations were reached at 1pore volume (PV), although BTCs showed peaks with lower concentrations in S+SMS. The amounts of cymoxanil retained only increased in S+SMS when a saturated-unsaturated flow was applied. A more relevant effect of SMS for reducing the leaching of fungicide was observed when cymoxanil was previously incubated in the column, although mineralization was enhanced in this case. These results are of interest for extending SMS application on the control of the leaching of fungicides with different physicochemical characteristics after different ageing times in the soil and water flow conditions applied.

“…Monitoring studies in agricultural areas where TCZ is used have verified its frequent presence in surface and groundwater systems (Herrero-Hernández et al, 2013;Sancez-Gonzalez et al, 2013). Although its dissipation and transformation in soil has been studied previously (Álvarez-Martín et al, 2016;Herrero-Hernández et al, 2013;Potter et al, 2005;Strickland et al, 2004), little is known regarding the fate of its transformation products in the environment (Storck et al, 2016).…”

Assessment of dissipation constitutes an integral part of pesticides risk assessment since it provides an estimate of the level and the duration of exposure of the terrestrial ecosystem to pesticides. Within the frame of an overall assessment of the soil microbial toxicity of pesticides, we investigated the dissipation of a range of dose rates of three model pesticides, isoproturon (IPU), tebuconazole (TCZ), and chlorpyrifos (CHL), and the formation and dissipation of their main transformation products following a tiered lab-to-field approach. The adsorption of pesticides and their transformation products was also determined. IPU was the least persistent pesticide showing a dose-dependent increase in its persistence in both laboratory and field studies. CHL dissipation showed a dose-dependent increase under laboratory conditions and an exact opposite trend in the field. TCZ was the most persistent pesticide under lab conditions showing a dose-dependent decrease in its dissipation, whereas in the field TCZ exhibited a biphasic dissipation pattern with extrapolated DT90s ranging from 198 to 603.4days in the ×1 and ×2 dose rates, respectively. IPU was demethylated to mono- (MD-IPU) and di-desmethyl-isoproturon (DD-IPU) which dissipated following a similar pattern with the parent compound. CHL was hydrolyzed to 3,5,6-trichloro-2-pyridinol (TCP) which dissipated showing a reverse dose-dependent pattern compared to CHL. Pesticides adsorption affinity increased in the order IPU

“…Most of these organic materials or biomasses can in fact allow the development of fungi producing extracellular ligninolytic enzymes that promote pesticide degradation (Castillo and Torstensson, 2007), preventing their transport to surface and ground waters (De Wilde et al, 2009). However, by decreasing the bioavailability of pesticides owing to their increased sorption capacity, the addition of an organic residue to soil may also decrease pesticide degradation (Briceño et al, 2007;Kravvariti et al, 2010;Álvarez-Martín et al, 2016b). Accordingly, there is increased interest in evaluating the sorption-desorption capacity of pesticides by the biomixtures of soil-organic residue as the principal component in the barrier system, which is the main element controlling immobilization and degradation efficacy, and therefore pesticide dissipation (Karanasios et al, 2012).…”

Lignocellulosic wastes and by-products containing lignin are now available in large amounts from forestry and industrial activities, and could be promising organic materials for the biosorption of pesticides by soils in order to reduce point-source pollution. Adding these materials to soil requires understanding the process of pesticide sorption-desorption by wood-soils, as sorption capacity could increase, with changes in pesticide bioavailability and final fate. The objective of this work was to study the effect that pine and oak wood added to soils had on the sorption/desorption of the pesticides linuron, alachlor, and metalaxyl. Experiments were conducted with two sandy loam and sandy clay soils each amended with two wood doses (5% and 50%) after different incubation times (0, 5 and 12 months). A low wood dose (5%) had no significant impact on the sorption (K) of alachlor, but K increased for linuron (up to 5.4-1.7 times) and metalaxyl (up to 4.4 and 8.6 times) in all wood-soil systems. The results were not significantly different after different incubation times. The desorption results indicated that wood decreases the sorption irreversibility of alachlor, and increases that of linuron and metalaxyl, with a varying effect of the wood-soil incubation time. The addition of a high wood dose to soil (50%) was more significant for increasing the sorption of all the pesticides, and the sorbed amounts remaining after desorption (>49% for linuron, >33% for alachlor and >6% for metalaxyl), although there was no apparent discrimination between the two types of woods. The role of the nature of the organic carbón (K values) for sorption was evidenced for alachlor and metalaxyl, but not for linuron. These outcomes are of interest for extending wood application to soil as a barrier for avoiding environmental risk by point-source pollution due to the use and management of pesticides in farming systems.
