Changes in the persistence of two phenylurea herbicides in two Mediterranean soils under irrigation with low- and high-quality water: A laboratory approach

Combining bioadsorption and photoelectrochemical oxidation for the treatment of soil‐washing effluents polluted with herbicide 2,4‐D

“…Concentration of pesticide in the soil washing fluid is not negligible but significant and, as expected, a treatment is required in order to regenerate the washing fluid. This concentration is comparable with the concentration used in most studies reported in the literature on pesticide degradation …”

Previous degradation study of two herbicides to simulate their fate in a sandy loam soil: Effect of the temperature and the organic amendments

“…Herbicide photodegradation was not considered, as soils were kept in the dark during incubation. It is also possible that soil sterilization was incomplete, especially in the amended soils with higher soil microbial biomass and activity, as indicated previously (ElGouzi et al, 2015). These results show that the degradation of chlorotoluron and flufenacet was mainly caused by microorganisms, as reported previously (ElGouzi et al, 2015;EC, 2003).…”

“…Under laboratory conditions, chlorotoluron DT 50 values ranged between 13 and 92 days (EC, 2005). The dissipation of this herbicide is mainly due to microbial transformation (ElGouzi et al, 2015 (EC, 2003). The persistence of flufenacet ESA in soil (DT 50 = 230 days) is higher than that of flufenacet OA (DT 50 = 11 days), posing a serious threat to water quality due to its huge potential for leaching (GUS index = 7.20) (EC, 2003;PPDB, 2018;(Ulrich et al, 2018).…”

A review of the impact of wastewater on the fate of pesticides in soils: Effect of some soil and solution properties

“…Among them, dehydrogenase activity has been widely considered as a good measure of the metabolic state of soil microorganisms (Watts et al, 2010;Järvan et al, 2014). In the study by ElGouzi et al (2015), as expected, the dehydrogenase activity was found to increase with SOM. However, this was not translated into a higher degradation of chlortoluron and isoproturon.…”
