“…However, organoclays also act as a mixed hydrophobic-hydrophilic sorbent attracting polar organic chemicals by both hydrophilic and polar bonds Hermosin et al, 1995;Stapleton et al, 1994;Vimond-Laboudigue et al, 1996;Zhao et al, 1996). The research of herbicide-clay interactions a field of maximum interest, as helping to develop and maximise remediation techniques for herbicide polluted areas (Hermosin and Cornejo, 1992;Hermosin et al, ,1995Dentel et al 1995;Xu et al, 1997;Bottero et al 1994;Weissmahr et al, 1997;Gonzales-Pradas et al, 1997;Lerch et al, 1997;Carrizosa et al 1999). Synthetic organic clays can also be used to have a better insight of the sorption mechanisms involved with natural organic clay associations existing in soil (Hermosin and Cornejo, 1992;Stapleton et al, 1994;Vimond-Laboudigue et al, 1996).…”

“…The adsorption of pesticides to different filter materials and soils is a part of the standard formulation of the compounds in order to get formal approval for commercial use, and has been investigated by several authors, mainly to describe the risk for leaching. There are several reports on the removal of pesticides from water, but only a few authors have focused on the use of filter materials as sorbents for pesticides in greenhouse productions (Bottero et al 1994;Torstensson et al 1994;Torrents & Jayasundera 1997;Konstantinou et al 2000;Kennedy et al 2001;Runes et al 2001;Kohler et al 2004;Haarstad & Braskerud 2005;Miller & Chin 2005;Blankenberg et al 2007;Cheng et al 2007;Dordio et al 2007; Rose et al 2007;Cejudo-Espinosa et al 2009), describing removal rates, half-lives and removal processes.…”

A research has been undertaken studying pesticide residues in water from greenhouses and the use of soils and filter materials to reduce such losses. The pesticides detected in water samples collected downstream greenhouses include 9 fungicides, 5 herbicides and 4 insecticides. 10 compounds from flower and vegetable productions were frequently found to exceed environmental risk levels, and with a few exceptions the compounds were found in higher concentrations than those typically found in agricultural runoff. Some compounds were found in high concentrations (>1 microg/l) in undiluted runoff from greenhouses producing vegetables. Nutrient concentrations in the runoff were also sporadically very high, with phosphorous values varying between 0.85 and 7.4 mg P/l, and nitrogen values between 7.5 and 41.4 mg N/l. Undiluted runoff from the productions showed values of 60 mg P/l and 300 mg N/l. High values of pesticides correlated with high values of nutrients, especially P. Column experiments using a sandy agricultural soil and stock solutions of non-polar and slightly polar pesticides mixed with a complex binder and nutrients showed a significant reduction for nearly all of the compounds used, indicating that transport through soil will reduce the concentrations of the studied pesticides. The pesticide adsorption capacity of the filter materials pine bark, peat, Sphagnum moss, compost, oat straw, ferrous sand and clay soil were tested in batch and column experiments. Adsorption were studied contacting the filter materials with aqueous solutions containing greenhouse production pesticides. The batch experiments showed that pine bark and peat, both combining a high content of organic matter with a low ph, provided the highest adsorption for most of the tested pesticides. Sphagnum moss, compost and oat straw also showed high adsorption for most of the pesticides, while the mineral filters provided the lowest adsorption (30-55%). Further column experiments confirmed these results, displaying the best removal efficiency in the organic materials, varying from 200 microg/g in compost, to 500 microg/g in moss, straw and pine bark.
