Adsorption of pesticides by sewage sludge, grape marc, spent mushroom substrate and by amended soils

Dissipation, metabolism and sorption of pesticides used in fruit-packaging plants: Towards an optimized depuration of their pesticide-contaminated agro-industrial effluents

“…This metabolic pattern deviates from the metabolic pattern observed in anaerobically digested sewage sludge. This could be attributed to the different compositions of those materials which are expected to support microbial communities with different metabolic capacities: anaerobically digested sewage sludge is mostly composed of hydrocarbons, amino acids and lipids compared to biobed materials which are mostly composed of cellulose, hemicellulose and lignin (Rodriguez-Cruz et al, 2012) and may favor aerobic oxidation processes. This is the first study providing data for the fate and the transformation of EQ in soil and biobed packing material.…”

Leaching of two fungicides in spent mushroom substrate amended soil: Influence of amendment rate, fungicide ageing and flow condition

“…They are characterized by a high organic carbon (OC) content and they are used simultaneously both as organic soil amendments to increase agricultural productivity (Courtney and Mullen, 2008;Udom et al, 2016) and as adsorbents of organic contaminants in soils, considering that OC is one of the most important soil factors influencing the adsorption process (Tran et al, 2015;Zolgharnein et al, 2011). The use of different organic residues with the potential to increase the adsorption of pesticides by soils has been reported in the literature (Ahmad et al, 2014;Marín-Benito et al, 2012;Rodríguez-Cruz et al, 2012). However, adsorption is not the only process controlling the future behavior of pesticides in soils.…”

Effect of different rates of spent mushroom substrate on the dissipation and bioavailability of cymoxanil and tebuconazole in an agricultural soil

“…Physicochemical methods to immobilize pesticides in vulnerable soils are currently being developed to prevent water contamination. Some of these methods include the use of different organic residues to modify soils, as their high organic matter (OM) content could limit the transport of pesticides from soil to groundwater and/or facilitate their dissipation, avoiding the diffuse or point pollution of waters due to the intensive use of these compounds (Rodríguez-Cruz et al, 2012;Álvarez-Martín et al, 2015).…”
