“…It is evident that the removal of PAHs has the "drag tail" phenomenon during three-time Fenton oxidation. In classical Fenton reaction, when H 2 O 2 is present in excess, more ·OH radical is available to react with the contaminants (Venny et al, 2012). In this study, 2 mL FeSO 4 ·7H 2 O (446 mmol L −1 ) and 3.33 mL H 2 O 2 (30%, w/w) were added to each flask in each oxidation process, the mass ratio of hydrogen peroxide and total PAHs in soil is greater than seventy.…”

“…A major challenge in Fenton treatment of PAHs-contaminated soils is the limited mass transfer of PAHs from the sorbed phase into the aqueous phase due to their strong sorption and low aqueous solubility (Yap et al, 2011). Limited mass transfer results in limited PAH available for the hydroxyl radical (·OH) which was generated in the aqueous phase (Venny et al, 2012). Therefore, integrating solubulizing agents (such as, co-solvent, surfactant, cyclodextrin and vegetable oil) with Fenton treatment is a possible alternative (Gan et al, 2009;Martens & Frankenberger, 1995; …”

“…Over the last two decades, Fenton treatment has emerged as a promising remediation technology for PAHs-polluted soils (Gan, Lau, & Ng, 2009;Gan et al, 2013;Martens & Frankenberger, 1995;Rosas, Vicente, Santos, & Romero, 2013;Saxe, Allen, & Nicol, 2000;Venny, Gan, & Ng, 2012;Yap, Gan, & Ng, 2011). Fenton oxidation processes are environmentally clean technologies which depend on the formation of reactive and non-selective hydroxyl (·OH) radicals for oxidation (Diyáuddeen, Aziz, & Daud, 2012).…”

Successive Fenton oxidation (up to three times) was conducted to enhance the removal efficiency of nine USEPA priority PAHs in aged soil highly contaminated with PAHs. Results showed that PAHs concentrations decreased rapidly and the removal efficiency was relatively high during one-time Fenton oxidation. However, PAHs in soil exhibited a slow removal trend and decreased at an extremely slow rate during two-and three-times Fenton oxidation. Surfactant Tween 80 was used to increase the amount of PAHs available for hydroxyl radical (·OH) and enhance Fenton oxidation efficiency of PAHs in aged soil pre-treated with Fenton reagents in this study.

“…Considerable efforts have been made to remediate contaminated soils (Zhang et al, 2013). Soil pollution is an increasing concern in many countries worldwide due to the detrimental short-term and long-term effects on humans, other life-forms and the environment (Venny et al, 2012). Soil metal-pollution as consequence of mining activities and/or other industrial activities represent a potential hazard for living organism due to high bioavailability of metals (Tordoff et al, 2000).…”

In case of significant technogenic geochemical loads on agricultural landscapes, the issue of ecological forecasting of environmental management is particularly important. Scientific studies of this issue are aimed at establishing the critical values for the components of the ecosystem, the classification of technogenic sources of hazardous substances, levels of soil contamination. This study presents a research to determine the content of heavy metals in the soils of the Ryazan region (Russia) and analyzed the level of their pollution. In the experiments organic, organomineral and mineral fertilizers systems were studied. From 2002 to 2008 were conducted lysimetric experiments on detoxification of elevated pollution of sod-podzol sandy loam soil, and from 2006 to 2008 of podzolized black soil. The participation of the non-ferrous metals plant emissions was detected in the pollution of sod-podzol light in granulometric composition soils with copper of up to 80 mg·kg-1, when the average concentration of Cu in the soil was 38.8 ±6 mg·kg-1. Humification plays a significant role in the formation of soil, its most important properties and characteristics. The saturation of 1 hectare of sown area with organic was slightly different in the experiments, but the intensity of accumulation of humus from the various agrochemical means did not almost differ. The problem of adaptation of plants in the conditions of technogenic environment is of primary importance. Plants have three biobarera against the admission of toxicants, these are the soil – the root – the stem – the reproductive organs. Grain in contaminated soil is environmentally hazardous as the content of Pb is indicated at the level of 0.68, 1.17 mg·kg-1 (MPC 0.5), Cd – 0.27, 0.11 mg·kg-1 (MPC 0.1), Zn – 76 mg·kg-1 (50 MPC). Use of fertilizing systems had a mostly positive effect, but products do not always become environmentally friendly.
