“…The low mobility of tebuconazole observed in the field trial was in accordance with the results of the laboratory sorption experiment indicating high sorption of the fungicide on the unamended and clay-and BCamended soil (Table 1). It also agreed with previous works reporting low leaching of tebuconazole in unamended soils and in soils treated with different organic amendments, in line with the high affinity of this fungicide for endogenous and exogenous soil organic matter (Aldana et al, 2011;Fenoll et al, 2011;Kalbe et al, 2014). Herrero-Hernández et al (2011), however, observed higher mobility of tebuconazole to deeper soil layers in a sandy clay loam soil amended with spent mushroom substrate compared to the unamended soil, and attributed this effect to the presence of dissolved organic matter released by the amendment.…”

“…It is highly polar and mobile in soils and besides organic matter, certain soil clay minerals may play an important role in its sorption (Bermúdez-Couso et al, 2011;Fernandes et al, 2003;Gondar et al, 2013;Sharma and Awasthi, 1997). The addition of organic amendments and modified clay minerals has been shown to enhance the retention of tebuconazole and/or metalaxyl in soils (Fenoll et al, 2011;Fernandes et al, 2006;HerreroHernández et al, 2011;Marín-Benito et al, 2012;Rodríguez-Cruz et al, 2007).…”

A B S T R A C TLaboratory and field experiments were conducted to assess how the addition of oleate-modified hydrotalcite (clay) and biochar (BC) to an agricultural soil affected the sorption, leaching, persistence, and enantiomeric composition of soil residues of two chiral fungicides, tebuconazole and metalaxyl. Laboratory experiments showed that the sorption of both fungicides ranked as follows: unamended soil < BC-amended soil < clay-amended soil. The addition of clay at a rate of 1% increased metalaxyl soil sorption coefficient (K d ) from 0.34 to 3.14 L kg À1 and that of tebuconazole from 2.4 to 47.4 L kg À1 . In our experimental set-up, field plots were either unamended or amended with clay (2 t ha À1 ) or BC (4 t ha À1 ), and subsequently treated with a mixture of tebuconazole and metalaxyl at 3 and 6 kg ha À1 , respectively. The leaching, persistence, and enantiomer composition of fungicides residues were monitored by sampling at different soil depths (0-5, 5-10, 10-20 cm) for 98 days. No significant changes in the scarce mobility and long persistence of tebuconazole upon amending the soil with clay or BC were observed. In contrast, sorption to clay and BC particles reduced the leaching and degradation of metalaxyl and the clay increased its persistence in the topsoil compared to the unamended soil. The enantioselective analysis of tebuconazole and metalaxyl soil residues indicated that tebuconazole remained mostly racemic along the experiment, whereas for metalaxyl the concentration of S-enantiomer was greater than the concentration of R-enantiomer, more so at longer experimental times and deeper horizons. Nevertheless, for the top 0-5 cm soil layer metalaxyl remained more racemic in clay-and BC-amended soil than in unamended soil. Our results show that addition of amendments with high sorptive capacities can be beneficial in reducing leaching and degradation losses of chiral pesticide enantiomers from the topsoil, and that sorption by the amendments can influence the final enantiomeric composition of pesticide residues.

“…In the second situation, besides the advantage of nutrients availability with low costs, organic waste use may be an important strategy to improve soil attributes damaged by degradation. This improvement can be reached not only by nutrient availability, but also by increasing soil organic matter (Piotrowska et al, 2011;Trejo et al, 2012;Fenoll et al, 2011). Among the advantages obtained by soil organic matter increase, the improvement of soil structure, water storage and soil biological parameters have been mentioned.…”

“…The use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. Some of the low-cost alternative adsorbents used include bamboo and coconut shell [40], cactus [41], rice husk [42], bamboo canes, peanut shells, olive stones, avocado stones, date stones, straw, wood sawdust [43], agave bagasse [44], rice bran, rice husk, bagasse fly ash of sugarcane, Moringa oleifera pods [45], sheep manure and spent coffee grounds [46], date and olives stones [47], oil palm shell [48], and coconut [49].…”

The presence of pesticides in the environment is of great concern due to their persistent nature and chronic adverse effect on human health and the environment. Water bodies are subject to pollution by organochlorine pesticides, especially in developing countries, where water pollution is a key sustainability challenge. Hence, activated carbon is considered a universal adsorbent for the removal of organochlorine pollutants from water. Activated carbon from Acatia etbaica was prepared using traditional kilns with low investment costs. Pesticides such as aldrin, dieldrin and DDT were selected for adsorption because of their common usage in agricultural and malaria control activities and may occur in high concentrations in surface waters that are used as drinking water sources. The effect of the adsorbent dose and initial concentration were investigated. To describe the equilibrium isotherms the experimental data were analyzed by the Langmuir and Freundlich isotherm models. The Freundlich model gave the best correlation with the experimental data. Activated carbon prepared from Acacia etbaica was found to be an effective and low-cost alternative for the removal of organochlorine pesticides from aqueous solutions. The preparation method allows the use of this material by local communities for effective remediation of pollution * Corresponding author. A. Gebrekidan et al. 279by pesticides.
