“…The obtained results were consistent with the hypothesis that the soil desorption process could lead to a balanced redistribution of contaminants between the solid and liquid phases, and the distribution of contaminants achieved a steady state in each desorption cycle (Ehsan, Prasher, & Marshall, 2007). Mao et al (2013) also found that the soil desorption efficiency of organochlorine pesticides by hydroxypropyl-β-cyclodextrin was improved after consecutive desorption.…”

In this work, the use of a coupled process, alkyl glycoside (APG) enhanced soil desorption followed by the zero‐valent iron–ethylenediaminetetraacetic acid (EDTA)–air (ZEA) Fenton‐like system, was investigated for the remediation of a simulated hexachlorobenzene (HCB)‐contaminated diatomite soil and a real HCB‐contaminated soil. Three surfactants with different concentrations were studied to obtain the suitable soil desorption agent. Compared with APG0810 and Triton x‐100, APG0814 showed a better solubilization effect due to its lower critical micelle concentration. With addition of 3000 mg L−1 APG0814, 35% of HCB was removed from contaminated diatomite soil, and a small amount of residual APG in diatomite soil was found to be beneficial for the soil dispersion. After treatment with the ZEA system, the removal efficiency of HCB in the diatomite soil desorption solution reached 76% in 2 h; we observed that a small amount of APG retained in the desorption solution accelerated the HCB removal. A real HCB‐contaminated soil was used to verify the remediation effects. This study demonstrates that our approach is a feasible alternative for remediating soil contaminated with hydrophobic organic compounds.

P esticides are the chemical substances which are used to kill harmful or which can damage the living organisms (Mathews, 2006). Pesticides have been put in to diferent classes based on their uses and handling e.g. bactericides, algicides, herbicides, fungicides, nematicides, insecticides, and rodenticides, while those having carbon rings are organophosphorus, carbamates, organochlorine, acetamides, Triazines and triazoles, pyrethroids and neonicotinoids (Tarla et al., 2020). During the period of green revolution in Pakistan, major focus was also to produce the harmless pesticides in order to control the widespread variety Abstract | Pesticides are the chemicals substances which are used for prevention of plant diseases, weeds and being used widely for increasing the quantity as well as quality of food products. Naturally, these pesticides interact with environment by altering the properties of host substances by producing the adverse impacts because most of the famers have no idea of using these chemicals substances. Pesticides are absorbed by soil particles which are transported to plants as well as animals through food chain and severely affect the ecosystem by causing acute or chronic disorders in the people of all ages. Similarly these pesticides cause serious threats to the aquatic ecosystem after their release by comprising different toxic substances, heavy metals and contaminants. This review paper has focused on the toxic nature of different pesticides, impacts and their possible refinement strategies from the environment as well as ways to minimize their impacts on plants and animals as adverse impacts of pesticides have also been observed on the human health, plants and other animals which need to control by reducing the use, release and synthesis on large scale.

“…Many of these studies have only determined the increasing solubility and complexation constants between specific pesticides with a variety of CDs (Orgoványi et al, 2009;Yáñez et al, 2012), but increasingly more studies can be found indicating the capacity of CDs for soil remediation based on their extractant ability and subsequent soil washing of a wide variety of pesticides, such as the herbicide norflurazon (Villaverde et al, 2005(Villaverde et al, , 2006, hexachlorobenzenes (Wan et al, 2009), other organochlorine pesticides (Wong and Bidleman, 2010;Mao et al, 2013;Ye et al, 2014a), 2,4-D, alachlor, metolachlor, acetochlor, dimethenamid, dicamba, and propanil (Flaherty et al, 2013). The enhanced extraction from soils facilitates subsequent phytoremediation (Ye et al, 2014b), oxidation (Villaverde et al, 2007) or biodegradation (Villaverde et al, 2012;Gao et al, 2015;Zhao et al, 2015).…”

The occurrence of pesticides in soil has become a highly significant environmental problem, which has been increased by the vast use of pesticides worldwide and the absence of remediation technologies that have been tested at full-scale. The aim of this review is to give an overview on technologies really studied and/or developed during the last years for remediation of soils contaminated by pesticides. Depending on the nature of the decontamination process, these techniques have been included into three categories: containment-immobilization, separation or destruction. The review includes some considerations about the status of emerging technologies as well as their advantages, limitations, and pesticides treated. In most cases, emerging technologies, such as those based on oxidation-reduction or bioremediation, may be incorporated into existing technologies to improve their performance or overcome limitations. Research and development actions are still needed for emerging technologies to bring them for full-scale implementation.
