“…Our results agree with Rojas et al (2013Rojas et al ( , 2014 who investigated the adsorption potential of several pesticides including alachlor on different soils with different organic matter and revealed that adsorption coefficient values increased with an increase in organic matter (OM) content of soil. Moreover, Dal Bosco et al (2012) emphasized the influence of total and dissolved organic matter from a biodigester and a treatment lagoon of swine wastewater in the adsorption and desorption of alachlor. In the same context, Wang et al (2015) revealed that the sorption behavior of diuron on Biochar (Enhanced Biochar, Hog Waste, Turkey Litter, Walnut Shell and Wood Feedstock) and an agricultural soil was well described by the Freundlich model (R(2) = 0.93-0.97) and the adsorbed amount was lower in soil than in the Biochar as in our case.…”

“…This situation was associated with health disabilities (Abu Mourad, 2000) and chronic diseases (Safi, 2002). In addition applied herbicides in soil were adsorbed on clay minerals (Franco et al, 1997), organoclay complexes (Nir et al, 2000), soil organic matter (Sa´nchez-Camazano et al, 2000;Rojas et al, 2013Rojas et al, , 2014, and dissolved organic matter from a biodigester (Dal Bosco et al, 2012).…”

The study investigated adsorption, leaching potential, and phytotoxicity of alachlor, bromacil, and diuron on melon, Molokhia, and wheat in Gaza strip. Plant height was used to estimate growth inhibition (phytotoxicity). Growth inhibition data were regressed versus concentrations of corresponding herbicide to estimate EC 50 value. The lowest EC 50 value indicates the highest phytotoxicity. Adsorption results indicated that alachlor, bromacil and diuron have different shapes. Leaching potentials indicated that alachlor totally disappeared from the top 5 cm and accumulated at a deeper depth whereas bromacil and diuron accumulated in the top 8 cm of soil layer with a decreasing intensity at deeper depth. Phytotoxicity tests showed that diuron has the lowest EC 50 values on melon (1.64) and Molokhia (0.15) whereas bromacil has the lowest one on wheat (0.08), values are in (mg/kg soil). Results of binary mixtures showed that the mixture contained alachlor and diuron was the most toxic to melon, whereas mixture contained alachlor and bromacil was the most toxic to Molokhia and wheat. Tertiary mixture (alachlor + bromacil + diuron) was more toxic on Molokhia than melon and wheat, EC 50 values were 3.02, 32.174, and 633.9 TU/kg soil on Molokhia, melon, and wheat respectively. An interesting outcome of the study is that Molokhia was the most sensitive plant and binary mixtures showed synergistic phytotoxicity.

“…The results indicate that the application of wood to soil at the low dose (5%) did not report an increase in alachlor sorption, although considerable sorption of alachlor by pine and oak woods (without soil) has been observed (Rodríguez-Cruz et al, 2007b). Some studies have reported that alachlor K d values increase in soils amended with other organic materials, such as lignocellulosic residue and cattle waste (Dorado et al, 2005) or swine wastewater (Dal Bosco et al, 2012). The behaviour of alachlor observed here could occur if wood had contributed to masking of sorption sites.…”

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.

“…Dal Bosco et al (2012) explored the effect of DOM extracted from two swine WW (either treated in a biodigester or in a treatment lagoon) on the adsorption/desorption behavior of the herbicide alachlor in a forest soil (Table 1). Four treatments, with rather high OC content (255-967 mg L -1 TOC), were evaluated.…”
