The widespread use of pesticides in modern agriculture is of increasing concern due to environmental contamination and subsequent biodiversity loss. Chlorpyrifos is a toxic organophosphate pesticide. Repeated applications of chlorpyrifos modify the soil microbial community structure and pose potential health risks to the other nontargets. Chlorpyrifos has been reported as the second most commonly detected pesticide in food and water. Extensive use of chlorpyrifos in agriculture and persistence in the environment have raised public concern and demand for safe technologies to overcome the pollution and toxicity problems. Here, we review pollution and toxicity issues associated with chlorpyrifos use and discuss strategies to solve pesticide contamination. Chlorpyrifos, previously shown to be resistant to enhanced degradation, has now been proved to undergo enhanced microbe-mediated decay. Here, special emphasis is given to degradation methods such as ozonation, Fenton treatment, photodegradation, and advanced oxidation processes along with microbial degradation. Finally, we focus on degradation process at enzyme and molecular levels which will enable us to elucidate the exact degradative pathway involved in biodegradation.

“…Recently, Tortella et al [91] demonstrated the increased degradation of the insecticide chlorpyrifos using Applied and Environmental Soil Science 7 an agricultural biobed system biostimulated with inorganic fertilizer (NPK). In yet another study, McGhee and Burns [92] reported the significant increase in degradation of herbicides 2,4-D and 4-chloro-2-methylphenoxyacetic acid (MCPA) following the addition of a combined NPK fertilizer.…”

Cleanup of herbicide-contaminated soils has been a dire environmental concern since the advent of industrial era. Although microorganisms are excellent degraders of herbicide compounds in the soil, some reparation may need to be brought about, in order to stimulate them to degrade the herbicide at a faster rate in a confined time frame. "Biostimulation" through the appropriate utilization of organic amendments and nutrients can accelerate the degradation of herbicides in the soil. However, effective use of biostimulants requires thorough comprehension of the global redox cycle during the microbial degradation of the herbicide molecules in the soil. In this paper, we present the prospects of using biostimulation as a powerful remediation strategy for the rapid cleanup of herbicide-polluted soils.

“…Finally, the biological activity in the biomixture increased due to the presence of NPK in all the evaluated concentrations. In conclusion, the results demonstrated that the biomix prepared with an Andisol and biostimulated with NPK nutrient can be recommended in biobeds as a viable alternative to chlorpyrifos dissipation, thereby avoiding the likelihood of soil and water contamination (Tortella et al 2010 ). By contrast, and taking into account that biostimulation of organicpollutant-degrading microorganisms by adding volatile organic compounds such as terpenes has been used to increase pollutant biodegradation in contaminated soils (Bento et al 2005 ;Tyagi et al 2011 ;Dudášová et al 2012 ), Tortella et al ( 2013d ) studied the effect of the terpenes α-pinene, eucalyptol, and limonene, individually and as mixtures, on atrazine biodegradation and on biological activity in a biobed biomixture.…”

“…As has been observed, pesticide degradation in biobeds can be limited or improved by several factors. Biostimulation of the indigenous microorganisms through the addition of nutrients is an important aspect to consider because the enrichment of the indigenous microbial populations is the most widely used tool in a bioremediation procedure (Tortella et al 2010 ). In this context and in order to ascertain the effect of biomixture stimulation, Tortella et al ( 2010 ) evaluated the degradation of chlorpyrifos (160 a.i.…”

The widespread use of pesticides for agricultural and for nonagricultural purposes worldwide has resulted in the presence of pesticide residues in various environmental matrices. The occurrence of pesticide residues in surface waters, groundwater, and large volumes of soil is mainly due to the inadequate management of these compounds. In this context, a biobed system was developed in Sweden in response to the need for a simple and effective way to minimize environmental contamination from pesticide manipulation, particularly when fi lling the spraying equipment, a typical point source of contamination. Biobeds are based on the adsorption and degradation potential of organic biomixtures composed of top soil, peat, and straw that fi lls a deep hole in the ground and a grass layer that covers the surface. Recently, the use of biobeds has expanded to other countries in Europe and Latin America. In Chile, four biobeds similar to the European ones have been installed, making this country a pioneer in this type of decontamination system. This chapter gives a general overview of biobeds technology and the advances in research at laboratory scale related to the treatment of pesticide residues in a biobed system in Chile.
